But how do you know whether those tests are actually useful?\n\nMost teams still rely on code coverage and pass rates to evaluate their test suites. The problem is that a test can pass, increase coverage, and still provide little or no additional confidence.\n\nWe've been seeing examples where AI-generated tests:\n\nDuplicate existing coverage\n\nDepend on system time or GUID generation\n\nAccess files, network resources, or environment variables\n\nUse ineffective or unnecessary mocking\n\nAdd maintenance cost without improving quality\n\nToday we launched Typemock Test Review, a tool that analyzes tests during execution and identifies duplicate, fragile, ineffective, and high-maintenance tests.\n\nInstead of looking only at source code, it combines runtime behavior, code coverage, dependency analysis, assertions, and mocking patterns to determine whether a test is actually contributing value.\n\nSome of the issues it can detect:\n\nDuplicate tests\n\nHidden external dependencies\n\nFlaky test risks\n\nUnused or stale fakes\n\nIneffective mocking\n\nTests that increase maintenance without increasing confidence\n\nI'm curious how other teams are dealing with the explosion of AI-generated tests.\n\nAre you reviewing AI-generated tests differently from manually written tests?
