Test Fixing

When your test suite is broken and you're staring at dozens of failures, this runs the tests, groups errors by type and root cause, then fixes them systematically. It tackles infrastructure issues first (imports, dependencies), then API changes, then logic bugs. The smart part is it verifies each group before moving on, so you're not chasing cascading failures. Works well when you've just refactored something and need to clean up the mess methodically rather than bouncing around random test files. It's basically the disciplined approach you know you should take but often skip when you're rushing.
