AI Testing Tools Mask Wrong-Target Errors in 25% of Locator Repairs

Summary
Roughly one-quarter of LLM-based locator repairs in the cited benchmark were false-heals, letting tests pass after switching to the wrong element instead of restoring the intended check.
Those failures stay hidden because three layers can all report success at once—the model completed a task, the harness passed, and production stayed healthy—even when they no longer describe the same behavior.
The report argues buyers should look beyond self-healing rates and demand wrong-target rates, abstention rates, and audit evidence showing how a repair changed a test’s semantic target.
Its proposed fix is a cross-layer evidence record linking model traces, test-run records, and application traces with a shared event ID, before-and-after targets, confidence scores, and human-review status.
The broader warning is that green dashboards measure execution continuity, not necessarily preservation of intent, so procurement and engineering metrics must track silent failures and weakened assertions explicitly.
