Frequently Asked Questions about xunit-skill

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write parameterized xUnit tests in C# using Theory and InlineData?

Parameterized xUnit tests use the [Theory] attribute combined with data sources like [InlineData], [MemberData], or [ClassData] to execute test logic across multiple datasets. This Skill generates these patterns to ensure comprehensive coverage for C# methods.

What is the best way to manage shared context in xUnit tests?

Shared context in xUnit tests is managed using the IClassFixture pattern. This Skill implements IClassFixture to handle setup and teardown logic, ensuring test isolation while sharing expensive object instances across multiple test methods.

Can I use FluentAssertions with xUnit when generating C# unit tests?

Yes, generated xUnit tests include common assertions using FluentAssertions. This integration provides a fluent syntax for verifying outcomes, making the generated C# test logic more readable and expressive.

How to scaffold a basic xUnit test for a C# class?

Scaffolding a basic xUnit test involves generating a C# class with the [Fact] attribute for a single test scenario. This Skill produces production-grade test code covering setup, execution, and assertion logic for target methods.

Does this xUnit test generator provide setup instructions for .NET projects?

Yes, the xUnit test generator includes setup instructions and debugging guidance specifically for .NET projects. It ensures your C# testing environment is configured correctly to run and troubleshoot xUnit.net tests.
