Integration testing with .NET Aspire uses xUnit IAsyncLifetime fixtures to boot your AppHost with real dependencies. This orchestrates actual infrastructure like databases and queues for deterministic end-to-end ASP.NET Core validations.

Dynamic endpoint discovery in Aspire testing automatically resolves runtime service URLs instead of hard-coding them. This allows xUnit tests to reliably locate and communicate with booted ASP.NET Core components during end-to-end validation.

Yes, xUnit IAsyncLifetime fixtures validate database readiness and messaging flows in Aspire. The fixtures orchestrate real infrastructure startup, enabling cross-service validation for databases, queues, and caches within ASP.NET Core workflows.

To write end-to-end tests for .NET Aspire service-to-service calls, use xUnit fixtures to boot your AppHost and leverage dynamic endpoint discovery. This setup lets you assert HTTP responses and verify cross-service interactions against real infrastructure.

Yes, .NET Aspire integration testing supports health checks for ASP.NET Core components. By orchestrating real infrastructure through xUnit fixtures, the workflow ensures services are fully booted and healthy before validating endpoint discovery and cross-service messaging.

Using Aspire fixtures for end-to-end testing requires booting real infrastructure like databases and queues, increasing test execution time and complexity. This approach is best suited for validating actual service interactions rather than fast, isolated unit-level logic testing.
