Root Cause

The code block inside pytest.raises() did not raise the expected exception, indicating a bug or incorrect test assumption.

generic

中文

pytest.raises() 内部的代码块未引发预期的异常，表明存在错误或不正确的测试假设。

Workarounds

  1. 90% success Review the code to ensure it raises the expected exception under the given conditions. 
    Add print statements or debug to verify the code path.
  2. 85% success Use pytest.raises with match parameter to check exception message. 
    with pytest.raises(ValueError, match='invalid value'): code_that_should_raise()

Dead Ends

Common approaches that don't work:

  1. Adding a try-except block inside pytest.raises to catch the exception 70% fail

    pytest.raises already handles exception catching; extra try-except may swallow the exception.

  2. Changing the expected exception to a broader type 60% fail

    This may mask the real issue where no exception is raised at all.
