+# WebSocket Integration Tests - Summary
+
+## Overview
+I've successfully created comprehensive integration tests for the WebSockets implementation in WireMock.Net. These tests are based on Examples 1 and 2 from `WireMock.Net.WebSocketExamples` and use `ClientWebSocket` to perform real WebSocket connections.
+
+## Test File Created
+- **Location**: `test\WireMock.Net.Tests\WebSockets\WebSocketIntegrationTests.cs`
+- **Test Count**: 13 integration tests
+- **Test Framework**: xUnit with FluentAssertions
+
+## Test Coverage
+
+### Example 1: Echo Server Tests (5 tests)
+1. **Example1_EchoServer_Should_Echo_Text_Messages**
+   - Tests basic echo functionality with a single text message
+   - Verifies message type and content
+
+2. **Example1_EchoServer_Should_Echo_Multiple_Messages**
+   - Tests echo functionality with multiple sequential messages
+   - Ensures each message is echoed back correctly
+
+3. **Example1_EchoServer_Should_Echo_Binary_Messages**
+   - Tests echo functionality with binary data
+   - Verifies binary message type and byte array content
+
+4. **Example1_EchoServer_Should_Handle_Empty_Messages**
+   - Tests edge case of empty messages
+   - Ensures the server handles empty content gracefully
+
+### Example 2: Custom Message Handler Tests (8 tests)
+1. **Example2_CustomHandler_Should_Handle_Help_Command**
+   - Tests `/help` command
+   - Verifies the help text contains expected commands
+
+2. **Example2_CustomHandler_Should_Handle_Time_Command**
+   - Tests `/time` command
+   - Verifies server time response format
+
+3. **Example2_CustomHandler_Should_Handle_Echo_Command**
+   - Tests `/echo <text>` command
+   - Verifies text is echoed without the command prefix
+
+4. **Example2_CustomHandler_Should_Handle_Upper_Command**
+   - Tests `/upper <text>` command
+   - Verifies text is converted to uppercase
+
+5. **Example2_CustomHandler_Should_Handle_Reverse_Command**
+   - Tests `/reverse <text>` command
+   - Verifies text is reversed correctly
+
+6. **Example2_CustomHandler_Should_Handle_Quit_Command**
+   - Tests `/quit` command
+   - Verifies goodbye message and proper WebSocket closure
+
+7. **Example2_CustomHandler_Should_Handle_Unknown_Command**
+   - Tests invalid commands
+   - Verifies error message is sent to client
+
+8. **Example2_CustomHandler_Should_Handle_Multiple_Commands_In_Sequence**
+   - Integration test running multiple commands in sequence
+   - Tests all commands together to verify state consistency
+
+## Key Features
+
+### Real WebSocket Testing
+- Uses `ClientWebSocket` for authentic WebSocket connections
+- Tests actual network communication, not mocked responses
+- Verifies WebSocket protocol compliance
+
+### Best Practices
+- Each test is isolated with its own server instance
+- Uses random ports (Port = 0) to avoid conflicts
+- Proper cleanup with `IDisposable` pattern
+- Uses FluentAssertions for readable test assertions
+
+### Coverage
+- Text and binary message types
+- Multiple message sequences
+- Command parsing and handling
+- Error handling for invalid commands
+- Proper connection closure
+
+## Running the Tests
+
+Run all WebSocket integration tests:
+```bash
+dotnet test --filter "FullyQualifiedName~WebSocketIntegrationTests"
+```
+
+Run only Example 1 tests:
+```bash
+dotnet test --filter "FullyQualifiedName~Example1"
+```
+
+Run only Example 2 tests:
+```bash
+dotnet test --filter "FullyQualifiedName~Example2"
+```
+
+## Dependencies
+The tests rely on:
+- `System.Net.WebSockets.ClientWebSocket`
+- `WireMock.Server.WireMockServer`
+- `FluentAssertions`
+- `xUnit`
+
+All dependencies are already included in the test project.
+
+## 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
