覆盖率-PermissionError：[Errno 1]不允许操作

问题描述

我将 pytest 和 coverage 模块用于测试用例和代码覆盖范围。

从项目根目录开始，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）如下：

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

[html]
directory = tests/coverage/html_report/

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

我做错了这个方法还是对如何解决这个问题有任何建议？

更新：

当我删除data_file = tests/coverage/时，coverage命令运行正常。但这是否应该发生，因为可以选择更改data_file here吗？

解决方法

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
