junit5 - 查明 assertAll 中的故障

问题描述

如果我assertAll在我的 JUnit 5 java 测试中有一个语句，并且它包含十几个断言，当其中一个失败时，它不会给我任何类型的行号，并且试图找出哪个失败可能是繁琐的任务（特别是如果它们是相似的断言，例如所有检查字符串或双精度）。

所以我想知道其他人是如何发现这一点的，以及你如何快速查明错误（就像你有多个单个断言并且其中一个失败时一样）。

这是我的堆栈跟踪的一个示例，我发现它对找出哪个断言失败没有帮助。它似乎只指向第 63 行，它是 assertAll() 语句的开头，仅此而已。

解决方案

由于assertAll从给定的可执行文件列表中整理所有断言失败并最终抛出一个AssertionFailedError- 它无法为每个失败提供堆栈跟踪条目。区分的简单方法是通过传递给断言的消息。
