覆蓋范圍 - PermissionError: [Errno 1] 不允許操作

Question

我使用pytest和覆蓋模塊進行測試用例和代碼覆蓋。

從項目根目錄，我可以執行pytest -v但不能執行pytest -v --cov=./ （下面的堆棧跟蹤）

我將PYTHONPATH設置為項目的根目錄。

目錄權限和所有權是drwxr-xr-x和saurabh staff 。 終端應用程序具有完整的磁盤訪問權限。

我的.coveragerc （位於項目根目錄）看起來像：

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

[html]
directory = tests/coverage/html_report/

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

我這樣做是錯誤的方式還是有關如何解決此問題的任何建議？

更新：

當我刪除data_file = tests/coverage/ ，coverage 命令工作正常。 不過，這應該是發生的事情，因為有改變DATA_FILE的選擇這里？

Answer 1

我可以通過將.coveragerc更改為：

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

[html]
directory = tests/coverage/html_report/

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