Csharp Xunit

This is Claude configured to help you write proper XUnit tests with a focus on real-world patterns. It covers the essentials like Arrange-Act-Assert structure, proper test naming conventions, and constructor/IDisposable setup patterns. Where it shines is data-driven testing guidance, walking you through InlineData, MemberData, and ClassData attributes plus custom data sources. It also handles test organization with class fixtures, collection fixtures, and trait categorization. The advice is practical and opinionated, pushing you toward independent tests and proper mocking patterns. Useful when you're setting up a new test project or trying to standardize your team's testing approach.
