Root Cause

The test module or package is missing from the Python path, often due to incorrect directory structure or missing __init__.py.

generic

中文

测试模块或包不在 Python 路径中，通常由于目录结构不正确或缺少 __init__.py。

Workarounds

  1. 90% success Ensure __init__.py exists in test directory 
    touch tests/__init__.py
  2. 85% success Run pytest with PYTHONPATH set 
    PYTHONPATH=. pytest

Dead Ends

Common approaches that don't work:

  1. Adding sys.path.append manually 50% fail

    Works temporarily but not portable; can cause path conflicts.

  2. Installing tests as a package via pip 70% fail

    Tests are not meant to be installed; they are run from source.
