SWE-Mutation - Test Generation - Claude Code: leaderboard
Detection of realistic mutation defects by repaired or newly generated tests. Paper v1 Tables 2-3 preserve both tasks and Mini-Swe-Agent/Claude Code scaffolds. RDR is Relative Detection Rate, not patch success; the default mutant generator is Claude Sonnet 4. This series reports Relative Detection Rate (%). Source: https://arxiv.org/html/2605.22175v1.
Metric: Relative Detection Rate (%). Source: arxiv.org. Saturation forecast: Estimated already saturated. 7 models tracked.
