MTP Hot Reload for Iterative Test Fixing

Set up and use a long-lived Microsoft Testing Platform host that applies code edits and automatically reruns tests.

When to Use

• User explicitly asks for test hot reload
• User wants a host to stay running and automatically rerun after repeated edits
• User needs to set up MTP hot reload in their project

When Not to Use

• User needs to write new tests from scratch (use general coding assistance)
• User needs to diagnose why a test is failing (use diagnostic skills)
• User asks about Visual Studio or VS Code Test Explorer hot reload or an IDE-integrated rerun experience (different feature, not MTP console-host hot reload)
• User asks whether the editor can auto-rerun affected tests after source edits without using an MTP console host
• User wants one normal run without rebuilding (use run-tests)
• User needs CI/CD pipeline configuration
