覆盖 - PermissionError：[Errno 1] 不允许操作

Question

我使用 pytest 和 coverage 模块进行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）

我将PYTHONPATH设置为项目的根目录。

目录权限和所有权是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

我这样做的方式是否错误或有任何关于如何解决此问题的建议？

更新：

当我删除data_file = tests/coverage/ 时，覆盖命令运行正常。但是这是否应该发生，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：

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

[html]
directory = tests/coverage/html_report/

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