根因分析

测试模块尝试将另一个测试模块作为包导入，但 tests 目录不是包（缺少 __init__.py）或导入路径不正确。

English

A test module tries to import another test module as a package, but the tests directory is not a package (missing __init__.py) or the import path is incorrect.

解决方案

  1. 90% 成功率 
    In conftest.py at project root:

import sys
from pathlib import Path
sys.path.insert(0, str(Path(__file__).parent))
  2. 95% 成功率 
    pip install -e .
Then in tests: from mypackage.tests.test_utils import helper
  3. 85% 成功率 
    Create a test_utils package at the project root and import from it:
from test_utils import helper

无效尝试

常见但无效的做法:

  1. 60% 失败

    This makes tests a package but can cause import conflicts with pytest's rootdir and may break other imports.

  2. 70% 失败

    Relative imports only work within packages; if tests is not a package, this fails.

  3. 80% 失败

    This is brittle and may not work consistently across different working directories.
