根因分析

被测代码未引发预期的异常，或异常在函数内部被捕获。

English

The code under test does not raise the expected exception, or the exception is caught inside the function.

generic

解决方案

  1. 90% 成功率 
    Run the function in a Python shell and check if it raises ValueError. If not, fix the function or update the test to expect the correct exception.
  2. 85% 成功率 
    with pytest.raises(ValueError):
    my_function()
This provides clearer error messages and works with pytest's assertion introspection.

无效尝试

常见但无效的做法:

  1. 90% 失败

    The test then passes even if no exception is raised, missing the intended validation.

  2. 70% 失败

    This may pass but does not verify the correct exception type, reducing test effectiveness.
