TestContainers spins up real databases, queues, and caches in Docker containers for .NET integration tests. This approach avoids mocks, ensuring reliable end-to-end verification of service interactions in reproducible environments.

Container lifecycle management during dotnet integration testing is handled through reusable containers and proper teardown. This provides deterministic test isolation and ensures CI/CD compatibility by cleaning up infrastructure after tests complete.

Yes, TestContainers works with xUnit for infrastructure testing in CI pipelines. It supports reproducible test environments locally and in CI by spinning up required containers to validate infrastructure interactions against production-like environments.

TestContainers supports deterministic test isolation for .NET applications by managing real container lifecycles. It spins up fresh instances of databases, queues, and caches for each test run and handles proper teardown to prevent state leakage.

Use real containers instead of mocks for integration testing when you need end-to-end verification of service interactions against production-like environments. Real infrastructure in Docker ensures reliability and validates actual database, queue, and cache behaviors.
