Does this skill support xUnit v2?

While it focuses on xUnit v3 and .NET 8+, it includes specific compatibility notes and migration patterns for projects moving from v2 to v3.

Can it help with integration testing?

Yes, it covers shared fixtures like IClassFixture and ICollectionFixture which are essential for database and API integration tests.

Does it configure parallel testing?

Yes, it includes guidance for assembly-level configuration via xunit.runner.json to control test concurrency and shared state.

How does it handle async tests?

It provides implementation patterns for xUnit v3's ValueTask return types in IAsyncLifetime for efficient asynchronous setup and teardown.

Security & Testing

Guides the implementation of robust unit and integration tests using the xUnit v3 framework for .NET 8.0+ projects.

This skill provides specialized guidance for authoring high-quality tests with xUnit v3, the latest evolution of the popular .NET testing framework. It streamlines the creation of parameterized tests using [Theory] and [InlineData], manages complex test lifecycles with IAsyncLifetime, and optimizes performance through parallel execution configurations. Whether you are migrating from xUnit v2 or starting a fresh .NET 8+ project, this skill ensures your test suites follow modern best practices, utilize strongly-typed data sources, and maintain high isolation with shared fixtures.
