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 whenever you edit code. ## Core Features & Use Cases - Guided Setup: Installs the Microsoft.Testing.Extensions.HotReload NuGet package and enables the TESTINGPLATFORM_HOTRELOAD_ENABLED environment variable via shell or launchSettings.json. - Framework-Aware Filtering: Provides the correct test filter syntax for MSTest, NUnit, xUnit v3, and TUnit so you iterate only on the failing tests. - Iterative Workflow: Runs the test host in console mode with dotnet run, watches for code changes, and re-executes affected tests automatically. - Use Case: You have three failing integration tests. 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 and run my failing tests so I can iterate on the fix without rebuilding.
