如何解决让 Intellij 坑测试插件在没有 Junit 错误的情况下运行？
我正在做作业，遇到了很多麻烦。我们的任务是在线获取一个开源项目，然后在原始程序员使用 Intellij 留在代码中的一堆 JUnit 测试上运行 PitTest。我在网上找到了这个视频 https://www.youtube.com/watch?v=KV5AZ8F7UHs，并一直在尽我所能地跟进。好吧，我找到了一个充满测试用例的示例项目，经过很多麻烦之后，将 PitTest 添加到 Intellij，构建项目并运行它。请理解我以前从未使用过 Intellij，上周才知道 JUnit 测试是什么。我很高兴看到没有发生错误，但当我打开报告时，它是空的。
结果我忘记在“其他参数”部分后添加要查找的突变。为了方便起见，我所做的只是在视频中添加“--mutators INCREMENTS”......然后bam......

沮丧我用谷歌搜索了很长时间，并在此处检查了类似的问题，了解为什么 JUnit 4 或任何与此相关的 Junit 不在类路径中，或者还有什么可能是问题。我的插件是最新的，PIT Runner 似乎也是如此，所以我不知道下一步该怎么做。我尝试了很多东西，但大多数（如果不是全部）在线“解决方案”对我来说都非常先进，或者看起来与我在 InteliJ 上的完全不同。大多数似乎他们在终端或其他地方工作。我并不急于解决这个问题，我有一周的时间来完成，但我真的很想早点解决这个问题。这看起来应该是一件容易的事情，但它一直是一个令人头疼的问题。
提前感谢您提供任何信息或指导。
