Checking that the SKILL.md file is still in the repository.

Defines .NET test strategy and implementation patterns across xUnit v3 (Facts, Theories, fixtures, IAsyncLifetime), integration testing (WebApplicationFactory, Testcontainers), Aspire testing (DistributedApplicationTestingBuilder), snapshot testing (Verify, scrubbing), Playwright E2E browser automation, BenchmarkDotNet microbenchmarks, code coverage (Coverlet), mutation testing (Stryker.NET), UI testing (page objects, selectors), and AOT WASM test compilation. Spans 13 topic areas. Do not use for production API architecture or CI workflow authoring.

Overview

Testing strategy, frameworks, and quality tooling for .NET applications. This consolidated skill spans 13 topic areas. Load the appropriate companion file from references/ based on the routing table below.

Baseline dependency: references/testing-strategy.md defines the unit vs integration vs E2E decision tree and test doubles selection that inform all testing decisions. Load it by default whenever a testing approach needs to be chosen.

Most-shared companion: references/xunit.md covers xUnit v3 framework features used by integration, snapshot, and UI testing companions.

Scope

  • Test strategy and architecture (unit, integration, E2E)
  • xUnit v3 test authoring
  • Integration testing (WebApplicationFactory, Testcontainers)
  • E2E browser testing (Playwright)

  • Quality (coverage, mutation testing)
  • Cross-framework UI testing patterns
  • Test scaffolding

Out of scope

  • UI framework-specific testing (bUnit, Appium) -> dotnet-ui
  • CI/CD pipeline configuration -> dotnet-devops
  • Performance profiling -> dotnet-tooling
