Summary
This gives Claude solid patterns for testing .NET apps with xUnit, FluentAssertions, and NSubstitute. You get concrete examples for unit tests with proper AAA structure, parameterized tests with Theory, mocking patterns that actually work, and integration tests using WebApplicationFactory and Testcontainers for real databases. It covers test data builders, project organization, and calls out common mistakes like testing implementation details or using Thread.Sleep. Activate this when writing new tests, reviewing coverage, or setting up test infrastructure. The examples are production-ready, not toy code, which makes it immediately useful for real codebases.
