Zero Changes Passed Our Quality Gate

Zero Changes Passed Our Quality Gate We have a pipeline that evaluates test quality beyond coverage. It scores files on 41 checks across categories like boundary testing, error handling, and security. When a file scores poorly, the system creates a PR and assigns an AI agent to improve the tests. Last week, the agent looked at a test file with 100% line coverage, said "nothing to improve," and closed the task with zero changes. Our verification gate passed it through. The tests were still weak. The agent wasn't being clever. Our gate had a gap. What the Tests Actually Looked Like The test file covered a function that transforms data and returns an object. Every line was exercised. But the assertions only checked that a return value existed: expect(result).toBeDefined(); expect(result).not.toBeNull(); The function always returns an object - it can never return undefined or null. These assertions pass no matter what the function does. You could replace the entire implementation with retu
