Testing Reliability

This skill focuses on test trustworthiness, not syntax. A test suite that passes for the wrong reason is worse than no test.

When to activate

• Flaky, timing-sensitive, or order-dependent tests.
• Heavy mocks, unclear patch targets, or fakes that do not match real behavior.
• Production code changed only to make tests easier.
• Coverage increased without stronger assertions.
• CI failures that cannot be reproduced locally.
