Rules for writing, running, and fixing tests. Invoke automatically whenever the user asks to write a test, add a test, fix a test, run tests, debug a failing test, check test coverage, or whenever the task involves touching files matching *.test.*, *.spec.*, __tests__/, or test/ directories.

Testing rules
Always check existing tests before creating a new one — match the style, helpers, and patterns already in the suite.
Never delete an existing test to make the suite pass. If a test looks unnecessary or wrong, ask the user before deleting.
When fixing a specific test, run that test file alone first (saves time). Only after it passes, run the full suite to check for regressions.
When asked to test something, do NOT modify production code to make tests pass. If you believe a bug prevents tests from passing, report it — don't silently fix it.
