解决方案

  1. 90% 成功率 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% 成功率 Use pytest.raises with match parameter to check exception message. 
    with pytest.raises(ValueError, match='invalid value'): code_that_should_raise()

无效尝试

常见但无效的做法:

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

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

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

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