根因分析

colcon test 需要在 setup.cfg 或 package.xml 中配置测试框架（pytest 或 unittest）；缺少或配置错误会导致测试发现失败。

English

colcon test requires a test framework (pytest or unittest) to be configured in setup.cfg or package.xml; missing or misconfigured entry causes test discovery failure.

解决方案

  1. 确保包根目录下的 setup.cfg 包含 [tool:pytest] 部分并列出测试路径。示例：
[tool:pytest]
testpaths = test

然后运行：colcon test --packages-select my_package
  2. 在 package.xml 中添加 pytest 的 test_depend 条目，并确保 test 目录中存在 conftest.py 或 __init__.py：
<test_depend>python3-pytest</test_depend>

然后重新构建：colcon build --packages-select my_package && colcon test

无效尝试

常见但无效的做法:

  1. Reinstalling pytest with pip without checking package configuration 70% 失败

    pytest is already installed; the issue is in the package's test configuration, not the framework itself.

  2. Adding a dummy test file without updating setup.cfg 85% 失败

    colcon uses setup.cfg or package.xml to discover tests; a test file alone is insufficient.

  3. Running pytest directly instead of colcon test 60% 失败

    pytest may work locally but colcon test uses a different discovery mechanism; this doesn't fix the colcon integration.
