What problem does it solve? Fixing failing tests normally requires a slow rebuild-and-rerun cycle for every code change. This Skill sets up Microsoft Testing Platform (MTP) hot reload so the test host stays running and automatically re-runs affected tests as you edit code, dramatically shortening the test-fix loop. ## Core Features & Use Cases - Platform Verification: Detects whether the project uses Microsoft Testing Platform or 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, supports framework-specific filters (MSTest, NUnit, xUnit v3, TUnit), and re-runs tests automatically on code changes. - Use Case: You have three failing unit tests after a refactor. Instead of rebuilding after each fix attempt, you enable hot reload, edit the production code, and watch the tests re-run instantly 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.
