java - 断言失败错误

Question

我在使用 junit 运行它时遇到以下问题:除了 testValidatePanelistIDHwid 之外，所有方法都工作正常。这是我在此类中添加的新方法，所有其他方法都可以正常工作。

神圣的鳄梨酱!您在每个测试中都包含很多测试。你能提供堆栈跟踪吗？或者不工作是什么意思？

编辑

扩展我的评论，这些测试中的每一个都应该是多个测试而不是一个，这可能是您找不到问题的根本原因之一。如果有什么东西坏了，测试应该非常非常清楚什么是坏的。

让我以测试 testIsMessageOfCorrectLength 为例。这是一个 3 个测试，您在一个测试中检查 4 个不同的预期结果(其中两个是相同的)。某些人(和我自己)认为好的测试代码库会将其分解为以下测试。

• testValidatesMessageOfMinimumLength
• testValidatesMessageOfIncorrectLength
• testMessageValidationThrowsExceptionIfMessageIsNull

如果将来有什么东西坏了，你会更清楚为什么坏了以及坏了什么。
