# WireMock.Net WebSocket Analysis - Executive Summary
|
||||
|
||||
## Overview
|
||||
|
||||
This analysis examines the WireMock.Net architecture and proposes a comprehensive WebSocket implementation strategy that maintains consistency with the existing fluent interface design patterns.
|
||||
|
||||
---
|
||||
|
||||
## Key Findings
|
||||
|
||||
### 1. Architecture Foundation
|
||||
|
||||
**WireMock.Net is built on three architectural layers:**
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────┐
|
||||
│ Abstractions Layer │
|
||||
│ (Interfaces & Models) │
|
||||
│ WireMock.Net.Abstractions │
|
||||
└──────────────────┬──────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌─────────────────────────────────────────┐
|
||||
│ Core Implementation Layer │
|
||||
│ (Full fluent interface) │
|
||||
│ WireMock.Net.Minimal │
|
||||
└──────────────────┬──────────────────────┘
|
||||
│
|
||||
↓
|
||||
┌─────────────────────────────────────────┐
|
||||
│ Integration Layers │
|
||||
│ (OWIN, StandAlone, Full) │
|
||||
│ WireMock.Net, WireMock.Net.StandAlone │
|
||||
└─────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
### 2. Fluent Interface Pattern
|
||||
|
||||
The fluent API is built on **four interconnected patterns:**
|
||||
|
||||
| Pattern | Purpose | Location | Key Files |
|
||||
|---------|---------|----------|-----------|
|
||||
| **Request Builder** | HTTP/WebSocket matching | RequestBuilders/ | `Request.cs` + `Request.With*.cs` |
|
||||
| **Response Builder** | HTTP/WebSocket responses | ResponseBuilders/ | `Response.cs` + `Response.With*.cs` |
|
||||
| **Mapping Builder** | Scenario orchestration | Server/ | `MappingBuilder.cs` + `RespondWithAProvider.cs` |
|
||||
| **Specialized Builders** | Domain-specific logic | ResponseBuilders/ | `WebSocketResponseBuilder.cs` (new) |
|
||||
|
||||
### 3. Design Principles
|
||||
|
||||
1. **Composition over Inheritance**: Partial classes separate concerns while maintaining fluent chains
|
||||
2. **Interface Segregation**: Consumers depend on small, focused interfaces
|
||||
3. **Method Chaining**: All builder methods return the builder type for fluency
|
||||
4. **Async-First**: Callbacks and transformers support both sync and async operations
|
||||
5. **Extensibility**: New features don't require changes to core classes
|
||||

## WebSocket Implementation Strategy
|
||||
|
||||
### Phase 1: Abstractions (WireMock.Net.Abstractions)
|
||||
|
||||
**Create new abstractions:**
|
||||
|
||||
```csharp
|
||||
IWebSocketMessage // Single message in stream
|
||||
IWebSocketResponse // Collection of messages + metadata
|
||||
IWebSocketResponseBuilder // Fluent builder for WebSocket config
|
||||
```
|
||||
|
||||
**Extend existing abstractions:**
|
||||
|
||||
```csharp
|
||||
// Update ResponseModel to include WebSocket config
|
||||
public class WebSocketResponseModel { ... }
|
||||
|
||||
// Update IResponseBuilder to support WebSocket
|
||||
public interface IResponseBuilder
|
||||
{
|
||||
IResponseBuilder WithWebSocket(Action<IWebSocketResponseBuilder> configure);
|
||||
// ... other WebSocket methods
|
||||
}
|
||||
|
||||
// Update IRequestBuilder for WebSocket matching
|
||||
public interface IRequestBuilder
|
||||
{
|
||||
IRequestBuilder WithWebSocketPath(string path);
|
||||
IRequestBuilder WithWebSocketSubprotocol(string subprotocol);
|
||||
// ... other WebSocket matching methods
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 2: Models (WireMock.Net.Minimal)
|
||||
|
||||
**Create new domain models:**
|
||||
|
||||
```
|
||||
Models/
|
||||
├── WebSocketMessage.cs // Individual message
|
||||
├── WebSocketResponse.cs // Response configuration
|
||||
```
|
||||
|
||||
### Phase 3: Request Builder Extension
|
||||
|
||||
**Create partial class:**
|
||||
|
||||
```
|
||||
RequestBuilders/
|
||||
└── Request.WithWebSocket.cs
|
||||
├── WithWebSocketUpgrade() // Match upgrade headers
|
||||
├── WithWebSocketPath() // Match path + upgrade
|
||||
├── WithWebSocketSubprotocol() // Match subprotocol
|
||||
├── WithWebSocketVersion() // Match WS version
|
||||
└── WithWebSocketOrigin() // Match origin (CORS)
|
||||
```
|
||||
|
||||
### Phase 4: Response Builder Extension
|
||||
|
||||
**Create new components:**
|
||||
|
||||
```
|
||||
ResponseBuilders/
|
||||
├── Response.WithWebSocket.cs // Add WebSocket methods to Response
|
||||
├── WebSocketResponseBuilder.cs // Fluent builder for messages
|
||||
└── WebSocketResponseBuilder.cs // IWebSocketResponseBuilder impl
|
||||
```
|
||||
|
||||
**Key methods:**
|
||||
|
||||
```csharp
|
||||
// Static messages
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("text message", delayMs: 0)
|
||||
.WithJsonMessage(obj, delayMs: 500)
|
||||
.WithBinaryMessage(bytes, delayMs: 1000)
|
||||
)
|
||||
|
||||
// Dynamic messages
|
||||
.WithWebSocketCallback(async request =>
|
||||
new[] { ... messages based on request ... }
|
||||
)
|
||||
|
||||
// Configuration
|
||||
.WithWebSocketTransformer()
|
||||
.WithWebSocketSubprotocol("protocol-name")
|
||||
.WithWebSocketClose(1000, "reason")
|
||||
.WithWebSocketAutoClose(delayMs)
|
||||
```
|
||||
|
||||
### Phase 5: Server Integration
|
||||
|
||||
**Update server components:**
|
||||
|
||||
```
|
||||
Server/
|
||||
├── WireMockServer.cs // Handle WebSocket upgrade
|
||||
├── WireMockMiddleware.cs // WebSocket middleware
|
||||
└── MappingMatcher.cs // Route WebSocket connections
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Usage Patterns
|
||||
|
||||
### Pattern 1: Simple Echo
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/echo"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketCallback(async req =>
|
||||
new[] { new WebSocketMessage { BodyAsString = req.Body } }
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 2: Sequence of Messages
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/stream"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("Starting", delayMs: 0)
|
||||
.WithMessage("Processing", delayMs: 1000)
|
||||
.WithMessage("Done", delayMs: 2000)
|
||||
.WithClose(1000)
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 3: Dynamic Content with Transformer
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/api"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new { user = "{{request.headers.X-User}}" })
|
||||
.WithTransformer()
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 4: State-Based Behavior
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/chat"))
|
||||
.InScenario("ChatRoom")
|
||||
.WhenStateIs("Authenticated")
|
||||
.WillSetStateTo("ChatActive")
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new { status = "authenticated" })
|
||||
)
|
||||
);
|
||||
```

|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|

|
||||
## Conclusion
|
||||
|
||||
The proposed WebSocket implementation maintains WireMock.Net's design philosophy of providing an intuitive, composable fluent API. By extending rather than replacing existing patterns, developers can leverage their knowledge of HTTP mocking to easily mock complex WebSocket scenarios.
|
||||
|
||||
The phased approach minimizes risk, the design supports both simple and complex use cases, and the fluent API ensures consistency across the entire platform.
|
||||
|
||||
**Recommendation**: Proceed with Phase 1 (Abstractions) to validate the design approach, then continue with subsequent phases based on community feedback.

# WebSocket Support in WireMock.Net - Fluent Interface Design Proposal
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document analyzes the WireMock.Net architecture and proposes a fluent interface design for WebSocket support in the `WireMock.Net.Minimal` project, following the established patterns in the codebase.
|
||||
|
||||
---
|
||||
|
||||
## Part 1: Current Architecture Analysis
|
||||
|
||||
### 1.1 Project Structure
|
||||
|
||||
**Core Projects:**
|
||||
- **WireMock.Net.Abstractions**: Defines interfaces and abstract models (no implementation)
|
||||
- **WireMock.Net.Minimal**: Core implementation with full fluent interface support
|
||||
- **WireMock.Net.StandAlone**: OWIN self-hosting wrapper
|
||||
- **WireMock.Net**: Full-featured version (extends Minimal)
|
||||
|
||||
### 1.2 Fluent Interface Pattern Overview
|
||||
|
||||
The fluent interface is built on three primary components working together:
|
||||
|
||||
#### **A. Request Builder Pattern** (`RequestBuilders/Request*.cs` files)
|
||||
|
||||
```csharp
|
||||
// Entry point
|
||||
var requestBuilder = Request.Create()
|
||||
.WithPath("/api/users")
|
||||
.UsingGet()
|
||||
.WithHeader("Authorization", "Bearer token");
|
||||
```
|
||||
|
||||
**Key Characteristics:**
|
||||
- Partial class `Request` with multiple `Request.WithXxx.cs` files
|
||||
- Each file focuses on a specific concern (Path, Headers, Params, etc.)
|
||||
- Implements `IRequestBuilder` interface
|
||||
- Returns `this` (IRequestBuilder) for chaining
|
||||
- Uses composition: `Request : RequestMessageCompositeMatcher, IRequestBuilder`
|
||||
|
||||
#### **B. Response Builder Pattern** (`ResponseBuilders/Response*.cs` files)
|
||||
|
||||
```csharp
|
||||
// Fluent response building
|
||||
Response.Create()
|
||||
.WithStatusCode(200)
|
||||
.WithHeader("Content-Type", "application/json")
|
||||
.WithBodyAsJson(new { id = 1, name = "John" })
|
||||
.WithDelay(TimeSpan.FromSeconds(1))
|
||||
.WithTransformer()
|
||||
```
|
||||
|
||||
**Key Characteristics:**
|
||||
- Partial class `Response` with separate files for features
|
||||
- Methods return `IResponseBuilder` (returns `this`)
|
||||
- Supports both sync and async callbacks via `WithCallback()`
|
||||
- Pluggable transformers (Handlebars, Scriban)
|
||||
- Examples:
|
||||
- `Response.WithCallback.cs`: Sync/async request handlers
|
||||
- `Response.WithTransformer.cs`: Template transformation
|
||||
- `Response.WithProxy.cs`: HTTP proxying
|
||||
- `Response.WithFault.cs`: Simulated faults
|
||||
|
||||
#### **C. Mapping Builder Pattern** (`MappingBuilder.cs` + `RespondWithAProvider.cs`)
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithPath("/endpoint"))
|
||||
.AtPriority(1)
|
||||
.WithTitle("My Endpoint")
|
||||
.InScenario("User Workflow")
|
||||
.WhenStateIs("LoggedIn")
|
||||
.WillSetStateTo("DataFetched")
|
||||
.WithWebhook(new Webhook { ... })
|
||||
.RespondWith(Response.Create().WithBody("response"))
|
||||
```
|
||||
|
||||
**Key Characteristics:**
|
||||
- `MappingBuilder.Given()` returns `IRespondWithAProvider`
|
||||
- `RespondWithAProvider` chains metadata (priority, scenario, webhooks)
|
||||
- Terminal method: `RespondWith(IResponseProvider)` or `ThenRespondWith()`
|
||||
- Fluent methods return `IRespondWithAProvider` for chaining
|
||||
- Example webhook support shows the pattern for extensions
|
||||
|
||||
### 1.3 Key Design Patterns Used
|
||||
|
||||
| Pattern | Location | Purpose |
|
||||
|---------|----------|---------|
|
||||
| **Partial Classes** | `Response.cs`, `Request.cs` | Separation of concerns while maintaining fluent interface |
|
||||
| **Builder Pattern** | `RequestBuilders/`, `ResponseBuilders/` | Incremental construction |
|
||||
| **Composite Pattern** | `RequestMessageCompositeMatcher` | Composable matchers |
|
||||
| **Interface Segregation** | `IResponseBuilder`, `IRequestBuilder` | Contract definition |
|
||||
| **Fluent API** | All builders | Method chaining |
|
||||
| **Extension Methods** | Various `*.cs` partial files | Feature addition without breaking changes |
|
||||
|
||||

|
||||
|
||||
## Part 2: WebSocket Support Design
|
||||
|
||||
### 2.1 Architecture for WebSocket Support
|
||||
|
||||
WebSocket support should follow a similar pattern to existing features. The key difference is that WebSockets are **bidirectional** and **stateful**, requiring:
|
||||
|
||||
1. **Request matching** (connection phase)
|
||||
2. **Message routing** (message handling)
|
||||
3. **State management** (connection state)
|
||||
4. **Simulated server messages** (push messages)
|
||||
|
||||
### 2.2 Proposed Model Classes (WireMock.Net.Abstractions)
|
||||
|
||||
Create new interfaces in `WireMock.Net.Abstractions`:
|
||||
|
||||
```csharp
|
||||
// File: Admin/Mappings/WebSocketModel.cs
|
||||
namespace WireMock.Admin.Mappings;
|
||||
|
||||
public class WebSocketMessageModel
|
||||
{
|
||||
public int? DelayMs { get; set; }
|
||||
public string? BodyAsString { get; set; }
|
||||
public byte[]? BodyAsBytes { get; set; }
|
||||
public bool IsText { get; set; } = true;
|
||||
}
|
||||
|
||||
public class WebSocketResponseModel
|
||||
{
|
||||
public List<WebSocketMessageModel> Messages { get; set; } = new();
|
||||
public bool UseTransformer { get; set; }
|
||||
public TransformerType TransformerType { get; set; } = TransformerType.Handlebars;
|
||||
public string? CloseMessage { get; set; }
|
||||
public int? CloseCode { get; set; }
|
||||
}
|
||||
```
|
||||
|
||||
### 2.3 Domain Models (WireMock.Net.Minimal)
|
||||
|
||||
Create new model in `Models/`:
|
||||
|
||||
```csharp
|
||||
// File: src/WireMock.Net.Minimal/Models/WebSocketMessage.cs
|
||||
namespace WireMock.Models;
|
||||
|
||||
public class WebSocketMessage : IWebSocketMessage
|
||||
{
|
||||
public int DelayMs { get; set; }
|
||||
public string? BodyAsString { get; set; }
|
||||
public byte[]? BodyAsBytes { get; set; }
|
||||
public bool IsText { get; set; } = true;
|
||||
}
|
||||
|
||||
// File: src/WireMock.Net.Minimal/Models/WebSocketResponse.cs
|
||||
namespace WireMock.Models;
|
||||
|
||||
public class WebSocketResponse : IWebSocketResponse
|
||||
{
|
||||
public List<IWebSocketMessage> Messages { get; set; } = new();
|
||||
public bool UseTransformer { get; set; }
|
||||
public TransformerType TransformerType { get; set; } = TransformerType.Handlebars;
|
||||
public string? CloseMessage { get; set; }
|
||||
public int? CloseCode { get; set; }
|
||||
}
|
||||
```
|
||||
|
||||
### 2.4 Request Builder Extension (WireMock.Net.Minimal)
|
||||
|
||||
Create partial class to extend request matching for WebSockets:
|
||||
|
||||
```csharp
|
||||
// File: src/WireMock.Net.Minimal/RequestBuilders/Request.WithWebSocket.cs
|
||||
namespace WireMock.RequestBuilders;
|
||||
|
||||
public partial class Request
|
||||
{
|
||||
/// <summary>
|
||||
/// Match WebSocket connection upgrade requests.
|
||||
/// </summary>
|
||||
public IRequestBuilder WithWebSocketUpgrade()
|
||||
{
|
||||
Add(new RequestMessageHeaderMatcher("Upgrade", new ExactMatcher("websocket")));
|
||||
Add(new RequestMessageHeaderMatcher("Connection", new WildcardMatcher("*Upgrade*")));
|
||||
return this;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Match specific WebSocket subprotocol.
|
||||
/// </summary>
|
||||
public IRequestBuilder WithWebSocketSubprotocol(string subprotocol)
|
||||
{
|
||||
Guard.NotNullOrWhiteSpace(subprotocol);
|
||||
Add(new RequestMessageHeaderMatcher("Sec-WebSocket-Protocol", new ExactMatcher(subprotocol)));
|
||||
return this;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Match WebSocket connection by path (typical pattern).
|
||||
/// </summary>
|
||||
public IRequestBuilder WithWebSocketPath(string path)
|
||||
{
|
||||
Guard.NotNullOrWhiteSpace(path);
|
||||
return WithPath(path).WithWebSocketUpgrade();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2.5 Response Builder Extension (WireMock.Net.Minimal)
|
||||
|
||||
Create partial class for WebSocket response handling:
|
||||
|
||||
```csharp
|
||||
// File: src/WireMock.Net.Minimal/ResponseBuilders/Response.WithWebSocket.cs
|
||||
namespace WireMock.ResponseBuilders;
|
||||
|
||||
public partial class Response
|
||||
{
|
||||
public IWebSocketResponse? WebSocketResponse { get; private set; }
|
||||
|
||||
public bool WithWebSocketUsed { get; private set; }
|
||||
|
||||
/// <summary>
|
||||
/// Configure WebSocket response with messages to send after connection.
|
||||
/// </summary>
|
||||
public IResponseBuilder WithWebSocket(Action<IWebSocketResponseBuilder> configure)
|
||||
{
|
||||
Guard.NotNull(configure);
|
||||
|
||||
var builder = new WebSocketResponseBuilder();
|
||||
configure(builder);
|
||||
|
||||
WithWebSocketUsed = true;
|
||||
WebSocketResponse = builder.Build();
|
||||
|
||||
return this;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Configure WebSocket response with a single message.
|
||||
/// </summary>
|
||||
public IResponseBuilder WithWebSocketMessage(string message, int? delayMs = null)
|
||||
{
|
||||
Guard.NotNullOrWhiteSpace(message);
|
||||
|
||||
return WithWebSocket(b => b
|
||||
.WithMessage(message, delayMs)
|
||||
);
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Configure WebSocket with async callback for dynamic message generation.
|
||||
/// </summary>
|
||||
public IResponseBuilder WithWebSocketCallback(
|
||||
Func<IRequestMessage, Task<IEnumerable<IWebSocketMessage>>> handler)
|
||||
{
|
||||
Guard.NotNull(handler);
|
||||
|
||||
WithWebSocketUsed = true;
|
||||
WebSocketCallbackAsync = handler;
|
||||
|
||||
return this;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Sets transformer for WebSocket messages.
|
||||
/// </summary>
|
||||
public IResponseBuilder WithWebSocketTransformer(
|
||||
bool use = true,
|
||||
TransformerType transformerType = TransformerType.Handlebars)
|
||||
{
|
||||
if (WebSocketResponse != null)
|
||||
{
|
||||
WebSocketResponse.UseTransformer = use;
|
||||
WebSocketResponse.TransformerType = transformerType;
|
||||
}
|
||||
|
||||
return this;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Configure WebSocket close frame (graceful disconnect).
|
||||
/// </summary>
|
||||
public IResponseBuilder WithWebSocketClose(int? closeCode = 1000, string? reason = null)
|
||||
{
|
||||
if (WebSocketResponse != null)
|
||||
{
|
||||
WebSocketResponse.CloseCode = closeCode;
|
||||
WebSocketResponse.CloseMessage = reason;
|
||||
}
|
||||
|
||||
return this;
|
||||
}
|
||||
|
||||
public Func<IRequestMessage, Task<IEnumerable<IWebSocketMessage>>>? WebSocketCallbackAsync { get; private set; }
|
||||
|
||||
public bool WithWebSocketCallbackUsed => WebSocketCallbackAsync != null;
|
||||
}
|
||||
```
|
||||
|
||||
### 2.6 WebSocket Response Builder (WireMock.Net.Minimal)
|
||||
|
||||
Create fluent builder for WebSocket messages:
|
||||
|
||||
```csharp
|
||||
// File: src/WireMock.Net.Minimal/ResponseBuilders/WebSocketResponseBuilder.cs
|
||||
namespace WireMock.ResponseBuilders;
|
||||
|
||||
public class WebSocketResponseBuilder : IWebSocketResponseBuilder
|
||||
{
|
||||
private readonly List<IWebSocketMessage> _messages = new();
|
||||
private bool _useTransformer;
|
||||
private TransformerType _transformerType = TransformerType.Handlebars;
|
||||
private int? _closeCode;
|
||||
private string? _closeMessage;
|
||||
|
||||
public IWebSocketResponseBuilder WithMessage(string message, int? delayMs = null)
|
||||
{
|
||||
Guard.NotNullOrWhiteSpace(message);
|
||||
|
||||
_messages.Add(new WebSocketMessage
|
||||
{
|
||||
BodyAsString = message,
|
||||
DelayMs = delayMs ?? 0,
|
||||
IsText = true
|
||||
});
|
||||
|
||||
return this;
|
||||
}
|
||||
|
||||
public IWebSocketResponseBuilder WithBinaryMessage(byte[] data, int? delayMs = null)
|
||||
{
|
||||
Guard.NotNull(data);
|
||||
|
||||
_messages.Add(new WebSocketMessage
|
||||
{
|
||||
BodyAsBytes = data,
|
||||
DelayMs = delayMs ?? 0,
|
||||
IsText = false
|
||||
});
|
||||
|
||||
return this;
|
||||
}
|
||||
|
||||
public IWebSocketResponseBuilder WithJsonMessage(object data, int? delayMs = null)
|
||||
{
|
||||
Guard.NotNull(data);
|
||||
|
||||

}
|

```
|
||||
|
||||
### 2.7 Usage Examples
|
||||
|
||||
#### **Basic WebSocket Echo**
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/echo"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("Connected to echo server")
|
||||
)
|
||||
.WithWebSocketCallback(async request =>
|
||||
{
|
||||
// Echo messages back from request body
|
||||
var messageText = request.Body;
|
||||
return new[]
|
||||
{
|
||||
new WebSocketMessage
|
||||
{
|
||||
BodyAsString = $"Echo: {messageText}",
|
||||
DelayMs = 100
|
||||
}
|
||||
};
|
||||
})
|
||||
);
|
||||
```
|
||||
|
||||
#### **Simulated Server - Multiple Messages**
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/chat"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("Welcome to chat room", delayMs: 0)
|
||||
.WithMessage("Other users: 2", delayMs: 500)
|
||||
.WithMessage("Ready for messages", delayMs: 1000)
|
||||
.WithTransformer()
|
||||
.WithClose(1000, "Room closing")
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
#### **JSON WebSocket API**
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create()
|
||||
.WithWebSocketPath("/api/notifications")
|
||||
.WithWebSocketSubprotocol("chat-v1"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new { type = "connected", userId = "{{request.headers.Authorization}}" })
|
||||
.WithJsonMessage(new { type = "notification", message = "You have a new message" }, delayMs: 2000)
|
||||
.WithTransformer()
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
#### **Dynamic Messages Based on Request**
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/data-stream"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketCallback(async request =>
|
||||
{
|
||||
var userId = request.Headers["X-User-Id"]?.FirstOrDefault();
|
||||
|
||||
var messages = new List<WebSocketMessage>();
|
||||
for (int i = 0; i < 3; i++)
|
||||
{
|
||||
messages.Add(new WebSocketMessage
|
||||
{
|
||||
BodyAsString = JsonConvert.SerializeObject(new
|
||||
{
|
||||
userId,
|
||||
sequence = i,
|
||||
timestamp = DateTime.UtcNow
|
||||
}),
|
||||
DelayMs = i * 1000,
|
||||
IsText = true
|
||||
});
|
||||
}
|
||||
|
||||
return messages;
|
||||
})
|
||||
);
|
||||
```
|
||||
|
||||
#### **Binary WebSocket (e.g., Protobuf)**
|
||||
|
||||
```csharp
|
||||
server.Given(Request.Create().WithWebSocketPath("/binary"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithBinaryMessage(protoBytes, delayMs: 100)
|
||||
.WithBinaryMessage(anotherProtoBytes, delayMs: 200)
|
||||
.WithClose(1000)
|
||||
)
|
||||
);
|
||||
```

|
||||

|
||||
|
||||
## Part 4: Key Design Decisions
|
||||
|
||||
### 4.1 Design Rationale
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| **Fluent API for WebSocket** | Consistent with existing Request/Response builders |
|
||||
| **Callback Support** | Enables dynamic message generation based on request context |
|
||||
| **Async Messages** | WebSocket communication is inherently async |
|
||||
| **Partial Classes** | Maintains separation of concerns (Path matching, Headers, WebSocket) |
|
||||
| **Builder Pattern** | Allows composing complex WebSocket scenarios incrementally |
|
||||
| **Message Queue** | Simulates realistic server behavior (message ordering, delays) |
|
||||
| **Transformer Support** | Reuses Handlebars/Scriban for dynamic message content |
|
||||
|
||||
### 4.2 Comparison with Existing Features
|
||||
|
||||
```csharp
|
||||
// Webhook (similar pattern - external notification)
|
||||
.WithWebhook(new Webhook { Request = new WebhookRequest { ... } })
|
||||
|
||||
// WebSocket (new - connection-based messaging)
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("...")
|
||||
.WithTransformer()
|
||||
)
|
||||
|
||||
// Callback (existing - dynamic response)
|
||||
.WithCallback(request => new ResponseMessage { ... })
|
||||
|
||||
// WebSocket Callback (new - dynamic WebSocket messages)
|
||||
.WithWebSocketCallback(async request =>
|
||||
new[] { new WebSocketMessage { ... } }
|
||||
)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Part 5: Implementation Considerations
|
||||
|
||||
### 5.1 Dependencies
|
||||
- **ASP.NET Core WebSocket support** (already available in Minimal)
|
||||
- **IRequestMessage/IResponseMessage** (reuse existing)
|
||||
- **Transformer infrastructure** (Handlebars/Scriban)
|
||||
- **Message serialization** (Newtonsoft.Json)
|
||||
|
||||
### 5.2 Edge Cases to Handle
|
||||
1. **Connection timeouts** - Server should be able to simulate client disconnect
|
||||
2. **Message ordering** - Ensure messages are sent in the order defined
|
||||
3. **Backpressure** - Handle slow clients
|
||||
4. **Concurrent connections** - Multiple WebSocket clients to same endpoint
|
||||
5. **Subprotocol negotiation** - Support WebSocket subprotocols
|
||||
|
||||
### 5.3 Testing Strategy
|
||||
1. Unit tests for `WebSocketResponseBuilder`
|
||||
2. Integration tests for connection matching
|
||||
3. Message ordering and delivery tests
|
||||
4. Transformer execution tests
|
||||
5. Callback execution tests
|
||||
|
||||
### 5.4 Breaking Changes
|
||||
- **None** - This is purely additive functionality following existing patterns
|
||||
|
||||
---
|
||||
|
||||
## Part 6: Integration Points
|
||||
|
||||
### 6.1 With Existing Features
|
||||
|
||||
```csharp
|
||||
// WebSocket + Scenario State
|
||||
server.Given(Request.Create().WithWebSocketPath("/status"))
|
||||
.InScenario("ServiceMonitoring")
|
||||
.WhenStateIs("Running")
|
||||
.WillSetStateTo("Stopped")
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws.WithMessage("Service is running"))
|
||||
);
|
||||
|
||||
// WebSocket + Priority
|
||||
server.Given(Request.Create().WithWebSocketPath("/ws"))
|
||||
.AtPriority(1)
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws.WithMessage("Priority response"))
|
||||
);
|
||||
|
||||
// WebSocket + Title & Description
|
||||
server.Given(Request.Create().WithWebSocketPath("/api"))
|
||||
.WithTitle("WebSocket API")
|
||||
.WithDescription("Real-time data stream")
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws.WithJsonMessage(data))
|
||||
);
|
||||
```
|
||||
|
||||
### 6.2 With Admin Interface
|
||||
```csharp
|
||||
// Retrieve WebSocket mappings
|
||||
var mappings = server.MappingModels
|
||||
.Where(m => m.Response.WebSocket != null)
|
||||
.ToList();
|
||||
|
||||
// Export WebSocket configuration
|
||||
var json = server.MappingModels[0].ToString();
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Conclusion
|
||||
|
||||
The proposed WebSocket support follows WireMock.Net's established fluent API patterns while adding the unique requirements of bidirectional, stateful WebSocket communication. The design:
|
||||
|
||||
✅ **Maintains consistency** with existing Request/Response builders
|
||||
✅ **Enables reuse** of transformers and matchers
|
||||
✅ **Provides flexibility** through callbacks and builders
|
||||
✅ **Supports testing** scenarios (timing, multiple messages, state)
|
||||
✅ **Integrates naturally** with existing features (scenarios, priority, webhooks)
|
||||
|
||||
This approach allows developers to mock complex WebSocket scenarios with the same familiar fluent syntax they use for HTTP mocking.

|
||||
## Part 1: Pattern Evolution in WireMock.Net
|
||||
|
||||
### HTTP Request Matching Pattern
|
||||
|
||||
```
|
||||
┌─────────────┐
|
||||
│ Request. │ Fluent methods return IRequestBuilder
|

│ WithPath │
|
||||
├─────────────┤
|
||||
│ WithHeader │
|
||||
├─────────────┤
|
||||
│ UsingGet() │ Each partial class file handles
|
||||
├─────────────┤ one concern (path, headers, method)
|
||||
│ WithParam │
|

├─────────────┤
|
||||
│ WithBody │
|

└─────────────┘
|

|
||||
└──────────────┘
|
||||
```
|
||||
|
||||
### WebSocket Extension Pattern (New)

||||
|
||||
```
|
||||
┌──────────────────────┐
|
||||
│ Request.Create() │
|
||||

|
||||
│ └─ WithTransformer() │
|
||||
├──────────────────────┤
|
||||
│ WithWebSocketCallback│ Dynamic message gen
|
||||
├──────────────────────┤
|
||||
│ WithWebSocketClose() │ Graceful shutdown
|
||||
└──────────────────────┘

## Part 2: Usage Pattern Comparison
|
||||
|
||||
### Pattern 1: Static Messages
|
||||
|
||||
**Analogy**: Pre-recorded HTTP responses
|
||||
|
||||
```csharp
|
||||
// HTTP (existing)
|
||||
server.Given(Request.Create().WithPath("/api/users"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithStatusCode(200)
|
||||
.WithBodyAsJson(new { id = 1, name = "John" })
|
||||
);
|
||||
|
||||
// WebSocket (new - sequential messages)
|
||||
server.Given(Request.Create().WithWebSocketPath("/api/users/stream"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new { type = "connected" }, delayMs: 0)
|
||||
.WithJsonMessage(new { id = 1, name = "John" }, delayMs: 500)
|
||||
.WithJsonMessage(new { id = 2, name = "Jane" }, delayMs: 1000)
|
||||
.WithClose(1000, "Stream complete")
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 2: Dynamic Content (Request-Based)
|
||||
|
||||
**Analogy**: Response callbacks
|
||||
|
||||
```csharp
|
||||
// HTTP (existing)
|
||||
server.Given(Request.Create().WithPath("/api/echo"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithCallback(request =>
|
||||
{
|
||||
return new ResponseMessage
|
||||
{
|
||||
BodyData = new BodyData
|
||||
{
|
||||
BodyAsString = $"Echo: {request.Body}",
|
||||
DetectedBodyType = BodyType.String
|
||||
},
|
||||
StatusCode = 200
|
||||
};
|
||||
})
|
||||
);
|
||||
|
||||
// WebSocket (new - message stream from request)
|
||||
server.Given(Request.Create().WithWebSocketPath("/echo"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketCallback(async request =>
|
||||
{
|
||||
// Generate messages based on request context
|
||||
return new[]
|
||||
{
|
||||
new WebSocketMessage
|
||||
{
|
||||
BodyAsString = $"Echo: {request.Body}",
|
||||
DelayMs = 100,
|
||||
IsText = true
|
||||
}
|
||||
};
|
||||
})
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 3: Templating (Dynamic Values)
|
||||
|
||||
**Analogy**: Handlebars/Scriban transformers
|
||||
|
||||
```csharp
|
||||
// HTTP (existing)
|
||||
server.Given(Request.Create().WithPath("/api/user"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithBodyAsJson(new {
|
||||
username = "{{request.headers.X-User-Name}}",
|
||||
timestamp = "{{now}}"
|
||||
})
|
||||
.WithTransformer()
|
||||
);
|
||||
|
||||
// WebSocket (new - template in messages)
|
||||
server.Given(Request.Create().WithWebSocketPath("/notifications"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new {
|
||||
user = "{{request.headers.X-User-Name}}",
|
||||
connected = "{{now}}"
|
||||
})
|
||||
.WithJsonMessage(new {
|
||||
message = "Hello {{request.headers.X-User-Name}}"
|
||||
}, delayMs: 1000)
|
||||
.WithTransformer()
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 4: Metadata (Scenario State)
|
||||
|
||||
**Analogy**: Scenario state management
|
||||
|
||||
```csharp
|
||||
// HTTP (existing)
|
||||
server.Given(Request.Create().WithPath("/login"))
|
||||
.InScenario("UserWorkflow")
|
||||
.WillSetStateTo("LoggedIn")
|
||||
.RespondWith(Response.Create()
|
||||
.WithStatusCode(200)
|
||||
.WithBodyAsJson(new { success = true })
|
||||
);
|
||||
|
||||
// WebSocket (new - state in WebSocket flow)
|
||||
server.Given(Request.Create().WithWebSocketPath("/chat"))
|
||||
.InScenario("ChatSession")
|
||||
.WhenStateIs("LoggedIn")
|
||||
.WillSetStateTo("ChatActive")
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new { type = "welcome" })
|
||||
.WithJsonMessage(new { type = "ready" })
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Pattern 5: Extensions (Webhooks)
|
||||
|
||||
**Analogy**: Side-effects during request handling
|
||||
|
||||
```csharp
|
||||
// HTTP (existing) - Trigger external webhook
|
||||
server.Given(Request.Create().WithPath("/process"))
|
||||
.WithWebhook(new Webhook
|
||||
{
|
||||
Request = new WebhookRequest
|
||||
{
|
||||
Url = "http://external-service/notify",
|
||||
Method = "post",
|
||||
BodyData = new BodyData { BodyAsString = "Processing..." }
|
||||
}
|
||||
})
|
||||
.RespondWith(Response.Create().WithStatusCode(200));
|
||||
|
||||
// WebSocket (new) - Webhook triggered by connection
|
||||
server.Given(Request.Create().WithWebSocketPath("/events"))
|
||||
.WithWebhook(new Webhook
|
||||
{
|
||||
Request = new WebhookRequest
|
||||
{
|
||||
Url = "http://audit-log/event",
|
||||
Method = "post",
|
||||
BodyData = new BodyData {
|
||||
BodyAsString = "WebSocket connected: {{request.url}}"
|
||||
}
|
||||
}
|
||||
})
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws.WithMessage("Connected"))
|
||||
);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Part 3: Real-World Scenarios
|
||||
|
||||
### Scenario 1: Real-time Chat Server
|
||||
|
||||
```csharp
|
||||
// Simulate multiple users joining a chat room
|
||||
server.Given(Request.Create()
|
||||
.WithWebSocketPath("/chat")
|
||||
.WithHeader("X-Room-Id", "room123"))
|
||||
.InScenario("ChatRoom")
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(
|
||||
new { type = "user-joined", username = "{{request.headers.X-Username}}" },
|
||||
delayMs: 0)
|
||||
.WithJsonMessage(

### Scenario 4: GraphQL Subscription Simulation
|

```

|
||||
|
||||
## Part 4: Best Practices
|
||||
|
||||
### ✅ DO: Follow Request Matching Patterns
|
||||
|
||||
```csharp
|
||||
// Good: Follows established request builder pattern
|
||||
server.Given(Request.Create()
|
||||
.WithWebSocketPath("/api/notifications")
|
||||
.WithWebSocketSubprotocol("notifications")
|
||||
.WithHeader("Authorization", "Bearer *")
|
||||
)
|
||||
```
|
||||
|
||||
### ❌ DON'T: Overload builders with raw configuration
|
||||
|
||||
```csharp
|
||||
// Bad: Breaks fluent pattern
|
||||
var req = new Request(...);
|
||||
req.webSocketSettings = new { ... };
|
||||
```
|
||||
|
||||
### ✅ DO: Use callbacks for dynamic behavior
|
||||
|
||||
```csharp
|
||||
// Good: Dynamic based on request context
|
||||
.WithWebSocketCallback(async request =>
|
||||
{
|
||||
var userId = request.Headers["X-User-Id"].First();
|
||||
return GetMessagesForUser(userId);
|
||||
})
|
||||
```
|
||||
|
||||
### ❌ DON'T: Mix static and dynamic in same mapping
|
||||
|
||||
```csharp
|
||||
// Bad: Confusing multiple patterns
|
||||
.WithWebSocket(ws => ws.WithMessage("Static"))
|
||||
.WithWebSocketCallback(async r => new[] { ... }) // Which wins?
|
||||
```
|
||||
|
||||
### ✅ DO: Use transformers for templating
|
||||
|
||||
```csharp
|
||||
// Good: Dynamic values via templates
|
||||
.WithJsonMessage(new
|
||||
{
|
||||
userId = "{{request.headers.X-User-Id}}"
|
||||
})
|
||||
.WithTransformer()
|
||||
```
|
||||
|
||||
### ❌ DON'T: Hardcode request values
|
||||
|
||||
```csharp
|
||||
// Bad: Doesn't adapt to different requests
|
||||
.WithJsonMessage(new { userId = "hardcoded-user-123" })
|
||||
```
|
||||
|
||||
### ✅ DO: Set appropriate delays for realistic simulation
|
||||
|
||||
```csharp
|
||||
// Good: Simulates realistic network latency
|
||||
.WithJsonMessage(msg1, delayMs: 0) // Immediate
|
||||
.WithJsonMessage(msg2, delayMs: 500) // 500ms later
|
||||
.WithJsonMessage(msg3, delayMs: 2000) // 2 seconds later
|
||||
```
|
||||
|
||||
### ❌ DON'T: Use excessively long delays
|
||||
|
||||
```csharp
|
||||
// Bad: Test hangs unnecessarily
|
||||
.WithJsonMessage(msg, delayMs: 60000) // 1 minute?
|
||||
```
|
||||
|
||||
### ✅ DO: Use subprotocol negotiation for versioning
|
||||
|
||||
```csharp
|
||||
// Good: Version the API
|
||||
.WithWebSocketPath("/api")
|
||||
.WithWebSocketSubprotocol("api.v2")
|
||||
```
|
||||
|
||||
### ❌ DON'T: Embed version in path alone
|
||||
|
||||
```csharp
|
||||
// Bad: Less testable for version negotiation
|
||||
.WithWebSocketPath("/api/v2")
|
||||
```
|
||||
|
||||
### ✅ DO: Chain metadata methods logically
|
||||
|
||||
```csharp
|
||||
// Good: Clear order (matching → metadata → response)
|
||||
server.Given(Request.Create().WithWebSocketPath("/api"))
|
||||
.AtPriority(1)
|
||||
.WithTitle("WebSocket API")
|
||||
.InScenario("ActiveConnections")
|
||||
.WithWebhook(...)
|
||||
.RespondWith(Response.Create()...);
|
||||
```
|
||||
|
||||
### ✅ DO: Test both happy path and error scenarios
|
||||
|
||||
```csharp
|
||||
// Connection accepted
|
||||
server.Given(Request.Create().WithWebSocketPath("/api").WithHeader("Auth", "*"))
|
||||
.RespondWith(Response.Create().WithWebSocket(...));
|
||||
|
||||
// Connection rejected
|
||||
server.Given(Request.Create().WithWebSocketPath("/api").WithHeader("Auth", "invalid"))
|
||||
.RespondWith(Response.Create().WithStatusCode(401));
|
||||
```
|
||||

|
||||
.WithWebSocketAutoClose(300000) // 5 minute timeout
|
||||
);
|
||||
```

|
||||
|
||||
## Summary
|
||||
|
||||
The WebSocket fluent interface design:
|
||||
|
||||
1. **Extends, not replaces** existing request/response builders
|
||||
2. **Follows established patterns** (partial classes, method chaining)
|
||||
3. **Enables composition** (messages, transformers, callbacks)
|
||||
4. **Maintains readability** (clear fluent chains)
|
||||
5. **Supports testing** (realistic delays, state, scenarios)
|
||||
6. **Integrates seamlessly** (webhooks, priority, metadata)
|
||||
|
||||
This ensures developers have a consistent, intuitive API for mocking WebSocket behavior.

# WebSocket Fluent Interface - Quick Reference
|
||||
|
||||
## At a Glance
|
||||
|
||||
### Current Architecture (HTTP Only)
|
||||
|
||||
```csharp
|
||||
// Request matching
|
||||
Request.Create()
|
||||
.WithPath("/api")
|
||||
.WithHeader("...")
|
||||
.UsingGet()
|
||||
|
||||
// Response building
|
||||
Response.Create()
|
||||
.WithStatusCode(200)
|
||||
.WithBodyAsJson(...)
|
||||
.WithTransformer()
|
||||
|
||||
// Mapping
|
||||
server.Given(request)
|
||||
.AtPriority(1)
|
||||
.InScenario("...")
|
||||
.RespondWith(response)
|
||||
```
|
||||
|
||||
### Proposed Addition (WebSocket Support)
|
||||
|
||||
```csharp
|
||||
// WebSocket request matching
|
||||
Request.Create()
|
||||
.WithWebSocketPath("/ws")
|
||||
.WithWebSocketSubprotocol("chat")
|
||||
|
||||
// WebSocket response building
|
||||
Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("Hello")
|
||||
.WithJsonMessage(obj)
|
||||
.WithTransformer()
|
||||
)
|
||||
.WithWebSocketCallback(async req => ... messages ...)
|
||||
|
||||
// Mapping (same as HTTP)
|
||||
server.Given(request)
|
||||
.RespondWith(response)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Quick Comparison: HTTP vs WebSocket Fluent API
|
||||
|
||||
### Request Builder
|
||||
|
||||
| HTTP | WebSocket |
|
||||
|------|-----------|
|
||||
| `WithPath(string)` | `WithWebSocketPath(string)` |
|
||||
| `WithHeader(string, string)` | `WithHeader(...)` (same) |
|
||||
| `UsingGet()` | `WithWebSocketUpgrade()` (implicit) |
|
||||
| `WithParam(string, string)` | (not applicable) |
|
||||
| `WithBody(string)` | (connection is upgrade, no body) |
|
||||
|
||||
### Response Builder
|
||||
|
||||
| HTTP | WebSocket |
|
||||
|------|-----------|
|
||||
| `WithStatusCode(int)` | `WithWebSocketClose(int)` |
|
||||
| `WithBody(string)` | `WithMessage(string)` |
|
||||
| `WithBodyAsJson(object)` | `WithJsonMessage(object)` |
|
||||
| (binary: rarely used) | `WithBinaryMessage(byte[])` |
|
||||
| `WithCallback(...)` | `WithWebSocketCallback(...)` |
|
||||
| `WithTransformer()` | `WithTransformer()` (same) |
|
||||
|
||||
### Mapping Configuration
|
||||
|
||||
| Feature | HTTP | WebSocket |
|
||||
|---------|------|-----------|
|
||||
| Priority | ✓ `AtPriority(int)` | ✓ `AtPriority(int)` |
|
||||
| Scenario | ✓ `InScenario(...)` | ✓ `InScenario(...)` |
|
||||
| Webhook | ✓ `WithWebhook(...)` | ✓ `WithWebhook(...)` |
|
||||
| Title/Desc | ✓ `WithTitle(...)` | ✓ `WithTitle(...)` |

## Code Examples
|
||||
|
||||
### Simple WebSocket
|
||||
|
||||
```csharp
|
||||
// Echo server
|
||||
server.Given(Request.Create().WithWebSocketPath("/echo"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketCallback(async req =>
|
||||
new[] { new WebSocketMessage { BodyAsString = req.Body } }
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Messages with Delays
|
||||
|
||||
```csharp
|
||||
// Multi-message response
|
||||
server.Given(Request.Create().WithWebSocketPath("/stream"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("First", 0)
|
||||
.WithMessage("Second", 500)
|
||||
.WithMessage("Third", 1000)
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Dynamic Messages
|
||||
|
||||
```csharp
|
||||
// Request-based generation
|
||||
server.Given(Request.Create().WithWebSocketPath("/api"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketCallback(async request =>
|
||||
{
|
||||
var userId = request.Headers["X-User-Id"].First();
|
||||
return new[]
|
||||
{
|
||||
new WebSocketMessage
|
||||
{
|
||||
BodyAsString = $"Hello {userId}"
|
||||
}
|
||||
};
|
||||
})
|
||||
);
|
||||
```
|
||||
|
||||
### Templated Messages
|
||||
|
||||
```csharp
|
||||
// Handlebars in message content
|
||||
server.Given(Request.Create().WithWebSocketPath("/api"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new
|
||||
{
|
||||
user = "{{request.headers.X-User}}"
|
||||
})
|
||||
.WithTransformer()
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### Subprotocol Negotiation
|
||||
|
||||
```csharp
|
||||
// Version-specific behavior
|
||||
server.Given(Request.Create()
|
||||
.WithWebSocketPath("/api")
|
||||
.WithWebSocketSubprotocol("v2"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocketSubprotocol("v2")
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("v2 protocol")
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
### With State Management
|
||||
|
||||
```csharp
|
||||
// Scenario-aware behavior
|
||||
server.Given(Request.Create().WithWebSocketPath("/chat"))
|
||||
.InScenario("ChatSession")
|
||||
.WhenStateIs("LoggedIn")
|
||||
.WillSetStateTo("ChatActive")
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithJsonMessage(new { status = "logged-in" })
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Design Principles
|
||||
|
||||
1. **Fluent First**: All builder methods return builder for chaining
|
||||
2. **Composable**: Messages, transformers, callbacks combine naturally
|
||||
3. **Consistent**: Follows HTTP mocking patterns and conventions
|
||||
4. **Extensible**: Partial classes allow feature additions without refactoring
|
||||
5. **Testable**: Deterministic, controllable message delivery
|
||||

|
||||
|
||||
## Integration Points
|
||||
|
||||
### With Existing Features
|
||||
|
||||
```csharp
|
||||
// Scenario management
|
||||
server.Given(Request.Create().WithWebSocketPath("/ws"))
|
||||
.InScenario("Session")
|
||||
.WhenStateIs("Connected")
|
||||
.WillSetStateTo("Active")
|
||||
.RespondWith(...)
|
||||
|
||||
// Priority ordering
|
||||
server.Given(Request.Create().WithWebSocketPath("/ws"))
|
||||
.AtPriority(1)
|
||||
.RespondWith(...)
|
||||
|
||||
// Webhooks
|
||||
server.Given(Request.Create().WithWebSocketPath("/ws"))
|
||||
.WithWebhook(new Webhook { ... })
|
||||
.RespondWith(...)
|
||||
|
||||
// Admin interface
|
||||
var mappings = server.MappingModels
|
||||
.Where(m => m.Response.WebSocket != null)
|
||||
.ToList()
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Testing Patterns
|
||||
|
||||
### Unit Test Template
|
||||
|
||||
```csharp
|
||||
[Fact]
|
||||
public void WebSocket_WithMultipleMessages_MaintainsOrder()
|
||||
{
|
||||
// Arrange
|
||||
var builder = new WebSocketResponseBuilder();
|
||||
|
||||
// Act
|
||||
var response = builder
|
||||
.WithMessage("First", 0)
|
||||
.WithMessage("Second", 100)
|
||||
.Build();
|
||||
|
||||
// Assert
|
||||
Assert.Equal("First", response.Messages[0].BodyAsString);
|
||||
Assert.Equal("Second", response.Messages[1].BodyAsString);
|
||||
Assert.Equal(100, response.Messages[1].DelayMs);
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Test Template
|
||||
|
||||
```csharp
|
||||
[Fact]
|
||||
public async Task WebSocket_Client_ReceivesMessages()
|
||||
{
|
||||
// Arrange
|
||||
var server = WireMockServer.Start();
|
||||
server.Given(Request.Create().WithWebSocketPath("/test"))
|
||||
.RespondWith(Response.Create()
|
||||
.WithWebSocket(ws => ws
|
||||
.WithMessage("Hello")
|
||||
.WithMessage("World")
|
||||
)
|
||||
);
|
||||
|
||||
// Act
|
||||
using var client = new ClientWebSocket();
|
||||
await client.ConnectAsync(new Uri($"ws://localhost:{server.Port}/test"), CancellationToken.None);
|
||||
|
||||
// Receive first message
|
||||
var buffer = new byte[1024];
|
||||
var result = await client.ReceiveAsync(buffer, CancellationToken.None);
|
||||
var message1 = Encoding.UTF8.GetString(buffer, 0, result.Count);
|
||||
|
||||
// Assert
|
||||
Assert.Equal("Hello", message1);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
| Aspect | Impact | Mitigation |
|
||||
|--------|--------|-----------|
|
||||
| Message queuing | Linear with message count | Use callbacks for large streams |
|
||||
| Memory | One message per connection | Implement cleanup on close |
|
||||
| Concurrency | Handle multiple connections | Use async callbacks |
|
||||
| Delays | Thread pool usage | Use reasonable delays (< 60s) |
|
||||
|
||||
---
|
||||
|
||||
## Common Issues & Solutions
|
||||
|
||||
### Issue 1: Message ordering
|
||||
**Problem**: Messages delivered out of order
|
||||
**Solution**: Use explicit delayMs, avoid concurrent message generation
|
||||
|
||||
### Issue 2: Connection timeout
|
||||
**Problem**: Client disconnects before messages sent
|
||||
**Solution**: Reduce message delays, increase test timeout
|
||||
|
||||
### Issue 3: Memory leak
|
||||
**Problem**: Connections not closing properly
|
||||
**Solution**: Always call `WithClose()` or `WithAutoClose()`
|
||||
|
||||
### Issue 4: Transformer not working
|
||||
**Problem**: Template variables not substituted
|
||||
**Solution**: Ensure `WithTransformer()` is called, check variable syntax
