Grove Testing Skill

When to Activate

Activate this skill when:

• Deciding what to test (not just how)
• Writing tests for new Grove features
• Reviewing existing tests for effectiveness
• Asked to "add tests" without specific guidance
• Evaluating whether tests are providing real value
• Refactoring causes many tests to break (symptom of bad tests)

For technical implementation (Vitest syntax, mocking patterns, assertions), use the javascript-testing skill alongside this one.
