根因分析

测试文件中的语法错误阻止 pytest 在收集期间导入该文件，因此整个模块被报告为错误，而不是运行任何测试。

English

A syntax error in the test file prevents pytest from importing it during collection, so the entire module is reported as an error rather than running any tests.

    python -m py_compile tests/test_math.py
  2. 92% 成功率

无效尝试

常见但无效的做法:

  1. 70% 失败

    Skips the broken module but hides the syntax error and leaves the test suite silently incomplete.

  2. 85% 失败

    SyntaxError is raised at parse time, before any import statement executes, so the try/except never runs.
