根因分析

当使用pytest --lf（上次失败）或--ff（首次失败）时，缓存中没有之前的测试运行数据，通常是因为缓存文件缺失或测试套件之前未运行过。

English

When using pytest --lf (last failed) or --ff (first failed), no previous test run data is available in the cache, often because the cache file is missing or the test suite has not been run before.

generic

解决方案

  1. 95% 成功率 Run the full test suite first to populate the cache, then use --lf 
    First run: pytest
Then run: pytest --lf
This will re-run only the tests that failed in the previous run.
  2. 80% 成功率 Use --co (cache-show) to inspect the cache contents 
    Run: pytest --co
This shows the cached results. If empty, run the full suite first.

无效尝试

常见但无效的做法:

  1. Running pytest --clear-cache to reset the cache 60% 失败

    This removes any existing cache, making the situation worse if there was data.

  2. Manually creating a cache file with dummy data 90% 失败

    This is error-prone and may cause pytest to misbehave if the format is incorrect.
