Fsharp Testing

This covers the full F# testing stack: xUnit for structure, FsUnit for idiomatic assertions, Unquote for quotation-based test failures that show you exactly what broke, and FsCheck for property-based testing. The examples are solid, from basic unit tests through async patterns, custom generators, and ASP.NET Core integration tests with WebApplicationFactory. The function stub approach for mocking is refreshingly practical compared to heavyweight mocking frameworks. Activate this when you're writing F# tests or setting up a test suite, especially if you want to move beyond basic assertions into property-based testing. The anti-patterns section alone is worth reading.
