根因分析

使用 pytest.raises(ValueError) 的测试期望引发异常，但代码执行时没有引发。

English

A test using pytest.raises(ValueError) expects an exception to be raised, but the code executes without raising it.

解决方案

  1. 90% 成功率 
    Check the code logic to ensure it raises ValueError under the given conditions, and fix if necessary.
  2. 85% 成功率 
    Add debug prints to verify the input that should trigger the exception.

无效尝试

常见但无效的做法:

  1. 95% 失败

    This defeats the purpose of the test; it should validate real error conditions.

  2. 80% 失败

    This can mask other unexpected exceptions and reduce test effectiveness.
