Skill: Test Preservation

Goal

Keep test coverage intact by fixing code or updating expectations instead of deleting tests.

Use This Skill When

• A test fails and you are tempted to remove or skip it.
• You think a test is outdated but the behavior still matters.

Do Not Use This Skill When

• You are intentionally replacing a test with a new one that covers the same behavior.

Steps

1. Read the Failure: Identify expected vs actual.
2. Fix Code First: Try to fix the implementation.
3. Validate Test: If behavior changed intentionally, update the test.
4. Preserve Coverage: If a test must be removed, replace it with an equivalent check.
