根因分析

自定义 Answer 实现 在测试调用期间抛出异常。

English

Custom Answer implementation throws an exception when invoked during test.

generic

解决方案

  1. 90% 成功率 Fix Answer implementation to handle edge cases 
    Answer<String> answer = invocation -> {
    if (invocation.getArgument(0) == null) {
        return "default";
    }
    return invocation.getArgument(0).toString();
};
  2. 85% 成功率 Use thenAnswer with lambda 
    when(mock.method(any())).thenAnswer(invocation -> {
    // safe logic
    return "result";
});

无效尝试

常见但无效的做法:

  1. Catching exception in test and ignoring 60% 失败

    Hides the real issue; test may pass incorrectly.

  2. Using thenThrow instead of custom Answer 40% 失败

    May not match the intended behavior if Answer has complex logic.
