aspire-integration-testing

You can write integration tests for .NET Aspire distributed applications using xUnit test fixtures that manage the application lifecycle, resolve dynamic endpoints, and verify service health checks against real infrastructure dependencies.

Testing .NET Aspire microservices with real dependencies involves orchestrating actual databases and services instead of mocks. xUnit fixtures using IAsyncLifetime manage environment setup and teardown, verifying distributed application components reliably.

Dynamic endpoint resolution in .NET Aspire integration tests automatically discovers service URLs at runtime, avoiding hardcoded addresses. The testing framework handles this discovery during fixture setup, allowing your xUnit tests to connect to orchestrated services reliably.

.NET Aspire integration testing works with xUnit by implementing IAsyncLifetime to manage test fixture setup and teardown. This combination handles the distributed application lifecycle and ensures real dependencies initialize before test execution.

Real infrastructure dependencies in .NET Aspire API testing verify actual interactions with databases like PostgreSQL and caches like Redis. This approach catches integration failures that mocks miss, ensuring your distributed application functions correctly before production deployment.

You can test ASP.NET Core APIs against real PostgreSQL databases and Redis caches managed by .NET Aspire. The framework orchestrates these dependencies, discovers their dynamic endpoints, and uses xUnit fixtures to validate API interactions in a production-like environment.
