Surefire 无法在 Surefire 报告中生成失败测试的完整堆栈跟踪

Question

我已将surefire "trimStackTrace" 更改为 false 以获取测试失败的完整堆栈跟踪，但生成的报告仅包含某些测试的堆栈跟踪。我使用junit 4.12和maven surefire“3.0.0-M5”。例如，对于同一个类（包 cc.mallet）中的两个测试，我得到这两个结果如下。在测试 13 中，我有完整的跟踪，但对于测试 16，我没有。是否可以在生成的肯定报告中包含失败测试的完整堆栈跟踪？ 测试 13：

 java.lang.AssertionError

    at cc.mallet.types.FeatureSequence.<init>(FeatureSequence.java:48)**

Answer 1

测试 16 是完整的堆栈跟踪。

如果您不想通过插件修剪堆栈跟踪，请设置trimStackTrace to false。
