Root Cause

A syntax error in a test module (or a module it imports) prevents pytest from collecting it. The error aborts collection for the whole file, so other tests in that file never run.

generic

中文

测试模块（或它导入的模块）中的语法错误导致 pytest 无法收集它。该错误会中止整个文件的收集，因此该文件中的其他测试永远不会运行。

Workarounds

  1. 95% success 
    python -m py_compile tests/test_models.py && pytest tests/test_models.py
  2. 90% success 
    ruff check tests/ && pytest

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Lets other files run but the broken file still contributes zero tests, silently reducing coverage.

  2. 75% fail

    The tests in that file are permanently skipped; the syntax error is never fixed.
