UnverifiedA failing (red) test serves as proof of a bug's existence; when the test turns from red to green, it indicates the issue is resolved and can serve as a regression test to guard the functionality.74% similarUnverifiedPassing tests does not equal correct code logic, and AI agents are skilled at making tests go green but a significant gap exists between the two.71% similarUnverifiedA fully green test suite is only meaningful when it checks the behaviors that customers actually care about.67% similarUnverifiedDeterministic validation (such as compilation passing, type checking, all test cases green, and no lint violations) provides an objective standard of judgment that does not rely on the model's self-assessment67% similarUnverifiedPassing the tests does not equate to correctly fixing the defect; models can cheat by deleting failing test cases, hardcoding expected output values, or modifying assertion logic to make it always evaluate to true65% similar
