This Skill helps developers write effective and maintainable unit tests in .NET using the xUnit.net framework, covering advanced features and best practices for reliable testing.
[Fact], [Theory], InlineData, MemberData, ClassData, fixtures (IClassFixture, ICollectionFixture), and IAsyncLifetime.Microsoft.Extensions.Logging.[Theory] with InlineData for different input scenarios and how to set up a fixture for any shared resources needed by your tests.Use the dotnet-xunit skill to learn how to write parameterized tests using [Theory] and InlineData.
High-intent search queries and answers about installing and using this skill.
To write parameterized unit tests in xUnit, use the [Theory] attribute combined with InlineData, MemberData, or ClassData to pass multiple input scenarios into a single test method.
To share resources across multiple xUnit test classes, implement ICollectionFixture to create a collection fixture that initializes shared state once for all tests within that collection.
You can control parallel test execution in xUnit by configuring parallelism settings, which allows you to enable or disable parallel execution for specific test collections to prevent state conflicts.
IAsyncLifetime provides asynchronous initialization and cleanup for xUnit unit tests, allowing you to await asynchronous operations during test setup and teardown without blocking threads.
Yes, you can capture test output in xUnit using ITestOutputHelper, which integrates with Microsoft.Extensions.Logging to route log messages directly into the test runner output.
Yes, xUnit includes analyzers that automatically inspect code to catch common testing mistakes and enforce best practices, improving the reliability of your test suite.
