TEBench - Stale Test Identification: leaderboard
Metric: Identification F1 (%) for tests left stale by the change: the tests the agent modified, deleted (method level) or added (file level) against the developer's own test changes, on TEBench (314 commits from 10 Java projects): given the project at the commit with its production changes but not its test changes, the agent edits the test suite in an isolated worktree with default agent settings; higher is better. Source: arxiv.org. Saturation forecast: Around March 2028. 7 models tracked.
