python - coverage.py 和 setup.py 以及 Django 测试

Question

我有一个带有 setup.py 的 Django 项目，如下所示:

.
├── backend
├── backoffice
├── backoffice_set
├── manage.py
├── MANIFEST.in
├── media
├── README.rst
├── requirements.txt
├── setup.py
└── venv2.7

当我运行时:python setup.py test 一切正常。但是，当我运行时:

/opt/bin/coverage run setup.py test

测试失败:

writing dependency_links to cfe_backoffice.egg-info/dependency_links.txt
reading manifest template 'MANIFEST.in'
warning: no files found matching '*' under directory 'backoffice/templates/backoffice/'
writing manifest file 'cfe_backoffice.egg-info/SOURCES.txt'

有没有人见过这个？您能提出解决方案吗？

Answer 1

好吧，过了一会儿我找到了解决方案。Django 没有全局安装，这正是我想要的。

我创建了我的虚拟环境:

 virtualenv --enable-system-packages

所以这导致 coverage.py 没有安装在我的 virtualenv 中。因此解决方案是强制 pip 使用 -I 安装它，这里是完整的操作日志:

/opt/bin/virtualenv --system-site-packages venv2.7
. venv2.7/bin/activate
pip install -r requirements.txt 
pip install -I coverage
coverage run setup.py test
