研究方向
Identify which individual tests or test groups are the slowest by profiling the test suite. Look into the test setup and configuration (e.g., in tests/ directory) for opportunities to parallelize or reduce resource usage. Check discussion in issue comments for any suggested approaches or prior attempts.
