testing + +## Key Testing Features + +### 🔌 Real WebSocket Connections +- Uses `System.Net.WebSockets.ClientWebSocket` +- Actual network communication +- Protocol compliance verification + +### 📤 SendJsonAsync Coverage +```csharp +await ctx.SendJsonAsync(new { + timestamp = DateTime.UtcNow, + message = msg.Text, + data = complexObject +}); +``` +- Simple objects +- Complex nested structures +- Arrays and collections + +### 📡 Broadcast Coverage +```csharp +await ctx.BroadcastTextAsync("Message to all"); +await ctx.BroadcastJsonAsync(jsonObject); +``` +- Multiple simultaneous clients +- Text and JSON broadcasts +- Connection state handling +- Scalability testing + +### ✨ Best Practices +- ✅ Test isolation (each test has own server) +- ✅ Random ports (Port = 0) +- ✅ Proper cleanup (`IDisposable`) +- ✅ FluentAssertions for readability +- ✅ Async/await throughout +- ✅ No test interdependencies ## Running the Tests -Run all WebSocket integration tests: +### All WebSocket Tests ```bash dotnet test --filter "FullyQualifiedName~WebSocketIntegrationTests" ``` -Run only Example 1 tests: +### By Example ```bash +# Example 1: Echo dotnet test --filter "FullyQualifiedName~Example1" + +# Example 2: Custom Handlers +dotnet test --filter "FullyQualifiedName~Example2" + +# Example 3: JSON +dotnet test --filter "FullyQualifiedName~Example3" ``` -Run only Example 2 tests: +### By

"FullyQualifiedName~Json" +``` + +### Run Specific Test +```bash +dotnet test --filter "FullyQualifiedName~Example1_EchoServer_Should_Echo_Text_Messages" ``` ## Dependencies -The tests rely on: -- `System.Net.WebSockets.ClientWebSocket` -- `WireMock.Server.WireMockServer` -- `FluentAssertions` -- `xUnit` -All dependencies are already included in the test project. +| Package | Purpose | +|---------|---------| +| `System.Net.WebSockets.ClientWebSocket` | Real WebSocket client | +| `WireMock.Server` | WireMock server instance | +| `FluentAssertions` | Readable assertions | +| `xUnit` | Test framework | +| `Newtonsoft.Json` | JSON parsing in assertions | -## Notes -- Tests use Port = 0 to automatically assign available ports -- Each test properly disposes of the server after completion -- Tests are independent and can run in parallel -- Binary message testing ensures support for non-text protocols +All dependencies are included in `WireMock.Net.Tests.csproj`. + +## Implementation Details + +### JSON Testing Pattern +```csharp +// Send text message +await client.SendAsync(bytes, WebSocketMessageType.Text, true, CancellationToken.None); + +// Receive JSON response +var result = await client.ReceiveAsync(buffer, CancellationToken.None); +var json = JObject.Parse(received); + +// Assert structure +json["message"].ToString().Should().Be(expectedMessage); +json["timestamp"].Should().NotBeNull(); +``` + +### Broadcast Testing Pattern +```csharp +// Connect multiple clients +var clients = new[] { new ClientWebSocket(), new ClientWebSocket() }; +foreach (var c in clients) + await c.ConnectAsync(uri, CancellationToken.None); + +// Send from one client +await clients[0].SendAsync(message, ...); + +// All clients receive +foreach (var c in clients) { + var result = await c.ReceiveAsync(buffer, ...); + // Assert all received the same message +} +``` + +## Test Timing Notes +- Connection registration delays: 100-200ms +- Ensures all clients are registered before broadcasting +- Prevents race conditions in multi-client tests +- Production code does not require delays + +## Coverage Metrics +- ✅ Text messages +- ✅ Binary messages +- ✅ Empty messages +- ✅ JSON serialization (simple & complex) +- ✅ Multiple sequential messages +- ✅ Multiple simultaneous clients +- ✅ Connection state transitions +- ✅ Broadcast to all clients +- ✅ Closed connection handling +- ✅ Error scenarios diff --git a/test/WireMock.Net.Tests/WebSockets/WebSocketIntegrationTests.cs b/test/WireMock.Net.Tests/WebSockets/WebSocketIntegrationTests.cs index
