Coverage - PermissionError: [Errno 1] Operation not permitted

Question

我使用 pytest 和 coverage 模块来测试用例和代码覆盖率。

从项目根目录，我可以执行 pytest -v 但不能执行 pytest -v --cov=./ （下面的堆栈跟踪）

我设置PYTHONPATH为项目根目录

目录权限和所有权为 drwxr-xr-x 和 saurabh staff。终端应用程序具有完整的磁盘访问权限。

我的 .coveragerc（位于项目根目录）看起来像：

[run]
data_file = tests/coverage/
omit = data-structures/*

[html]
directory = tests/coverage/html_report/

[xml]
output = tests/coverage/coverage.xml

PermissionError: [Errno 1] Operation not permitted: '/Users/saurabh/Desktop/Data Structures/tests/coverage'

我是不是做错了，或者有什么解决方法的建议吗？

更新:

当我删除 data_file = tests/coverage/ 时，覆盖命令工作正常。但这应该发生吗，因为有一个选项可以更改 data_file here ?

Answer 1

我可以通过将 .coveragerc 更改为：

来使其正常工作

[run]
omit = data-structures/*
data_file = tests/coverage/.coverage

[html]
directory = tests/coverage/html_report/

[xml]
output = tests/coverage/coverage.xml
