Can I control how tests run in parallel?

Yes, you can use CollectionDefinition to disable parallelization for specific tests or create an xunit.runner.json file for assembly-wide configuration.

Does this skill support xUnit v2?

Yes, while it focuses on xUnit v3 (.NET 8.0+), it includes specific compatibility notes and implementation patterns for xUnit v2 projects.

What is the best way to share a database connection between tests?

Use IClassFixture for sharing a resource within a single class, or ICollectionFixture to share a resource across multiple different test classes.

How do I handle async setup in xUnit v3 versus v2?

In xUnit v3, the IAsyncLifetime interface methods return ValueTask, whereas in v2 they return Task. This skill provides the correct syntax for both.

セキュリティとテスト

Authors and optimizes xUnit v3 and v2 tests for .NET applications, including complex data-driven theories and shared fixtures.

The dotnet-xunit skill provides specialized guidance for implementing professional-grade test suites using the xUnit framework. It covers the latest v3 features like ValueTask-based async lifecycles and strongly-typed TheoryData, while maintaining backward compatibility for v2 projects. Developers can use this skill to implement robust testing patterns, manage expensive resources via class and collection fixtures, and fine-tune parallel execution settings for optimal CI/CD performance.
