Run Azure Functions integration tests

Run Azure Functions integration tests for the Datadog .NET tracer.

Test options:

1. Full Azure Functions test suite:

   .\build.cmd BuildAndRunWindowsAzureFunctionsTests
   

2. Run specific test projects:

   dotnet test tracer/test/Datadog.Trace.ClrProfiler.IntegrationTests/Datadog.Trace.ClrProfiler.IntegrationTests.csproj --filter "FullyQualifiedName~AzureFunctions"
   

3. Test with specific function app samples:

   • Sample apps location: tracer/test/test-applications/azure-functions/
   • Available samples:
     • In-process (.NET Framework, .NET 6+)
     • Isolated worker (.NET 5+, .NET 7+)
     • HTTP triggers, timer triggers, queue triggers
     • Various runtime versions

Test scenarios covered:

• In-process model: Functions running in the same process as the host
• Isolated worker model: Functions running in separate worker process
• Instrumentation: Auto-instrumentation via site extension or NuGet package
• Trace propagation: HTTP headers, queue messages
• Metrics: Runtime metrics, custom metrics
• Logging: ILogger integration with Datadog

Before running tests:

1. Ensure Docker is running (some tests require containers)
2. Check Azure Functions Core Tools are installed: func --version
3. Verify build is up to date

Common test filters:

• --filter "Category=AzureFunctions" - All Azure Functions tests
• --filter "Category=Smoke&FullyQualifiedName~AzureFunctions" - Smoke tests only
• --framework net6.0 - Specific framework

After running:

• Review test results (passed/failed/skipped)
• Check test logs for instrumentation verification
• Analyze any failures for patterns
• Verify traces are properly generated
