How do I see output from xUnit's ITestOutputHelper?

The skill provides specific logger configurations and verbosity flags (detailed) that ensure internal test output is visible in the console.

Does it help with debugging hanging tests?

The skill includes references for advanced debugging scenarios like using --blame mode to diagnose test crashes and hangs.

How does this skill improve .NET test performance?

It implements a build-first approach followed by test execution using the --no-build flag, eliminating redundant compilation steps during iterative testing.

Can I use this with frameworks other than xUnit?

Yes, while the primary focus is xUnit, the skill includes documentation for MSTest and NUnit filter property differences such as TestCategory and Priority.

Can I filter tests by specific methods or namespaces?

Yes, it includes patterns for filtering by FullyQualifiedName, ClassName, and Name using operators like exact match (=) or contains (~).

Security & Testing

Optimizes .NET test execution through a build-first, targeted workflow that prioritizes speed and selective xUnit filtering.

This skill enhances Claude's ability to manage .NET testing environments by implementing a high-performance 'build once, test many' workflow. It provides specialized guidance for running xUnit, MSTest, or NUnit tests selectively, using advanced filter expressions and optimized CLI commands to reduce developer wait times. By skipping redundant builds and providing precise output logging, it enables faster feedback loops during the development and debugging phases of C# and .NET projects.
