What problem does it solve? Fixing failing tests normally requires a full rebuild and test run for every code change, which slows down the fix-verify loop. This Skill sets up Microsoft Testing Platform (MTP) hot reload so the test host stays running and automatically re-runs affected tests when you edit code. ## Core Features & Use Cases - Platform Detection: Verifies the project uses Microsoft Testing Platform rather than VSTest, since hot reload only works with MTP. - Guided Setup: Walks through installing the Microsoft.Testing.Extensions.HotReload NuGet package and enabling the TESTINGPLATFORM_HOTRELOAD_ENABLED environment variable via shell or launchSettings.json. - Iterative Workflow: Runs tests with dotnet run in console mode, applies framework-specific filters (MSTest, NUnit, xUnit v3, TUnit), and re-runs tests automatically on code changes. - Use Case: You have three failing xUnit tests. After setup, you start the test host once, edit the production code, and watch the tests re-run instantly after each save until they pass. ## Quick Start Set up MTP hot reload in my test project so I can iterate on my failing tests without rebuilding between changes.
