Elsa.Http Integration Tests

This test project contains integration tests for HTTP-related activities in Elsa Workflows, specifically focusing on HTTP context loss scenarios.

Status

✅ Tests are working! All tests pass successfully and are properly discovered by xUnit.

Test Coverage

HttpContextLossTests

Tests that verify the behavior of HTTP response activities when the HTTP context is lost during workflow execution.

Test Scenarios

1. WriteHttpResponse_WithNoHttpContext_ShouldRecordIncident

   • Verifies that WriteHttpResponse activity records an incident when HTTP context is null
   • Validates that the incident message clearly explains the HTTP context loss scenario
   • Status: ✅ Passing

2. WriteFileHttpResponse_WithNoHttpContext_ShouldRecordIncident

   • Verifies that WriteFileHttpResponse activity records an incident when HTTP context is null
   • Validates the incident message contains expected information
   • Status: ✅ Passing

Expected Behavior

When HTTP context is not available:

• Fault Code: NoHttpContext
• Fault Category: HTTP
• Fault Type: System
• Error Message: Detailed explanation including:
  • What happened: HTTP context was lost during workflow execution
  • Why it happened: Workflow suspended and resumed in different execution context
  • Common scenarios: Background processing, virtual actor, workflow transition
  • Impact: Original HTTP request context no longer available
• Result: An ActivityIncident is recorded with the fault message

Implementation Notes

• Tests use WorkflowTestFixture from Elsa.Testing.Shared for consistent test setup
• Workflow classes are separated into individual files in the Workflows subfolder for better organization
• NullHttpContextAccessor is a test helper that simulates HTTP context loss by always returning null
• Tests automatically build the fixture and populate registries before execution
