+## A Live Benchmark for Test Generation & Test Update
+
+Evaluating how AI agents understand and adapt tests to real-world software evolution.

+
+TestEvo-Bench is a live benchmark for evaluating AI software engineering agents on realistic software test evolution tasks mined from open-source repositories.
+
+Unlike traditional benchmarks that isolate tests from production changes, TestEvo-Bench models real software co-evolution between production code and test suites.
+
+The benchmark contains two complementary tracks:
+
+- 🟠 **Test Generation** — generate new tests for newly introduced behavior
+- 🟣 **Test Update** — repair or adapt outdated tests after code changes
+
+Each task is execution-grounded with runnable environments and evaluated using metrics such as pass rate, coverage, and mutation score.
