我正在完成一项学校作业，遇到了很多麻烦。我们的任务是在线获取一个开源项目，然后在一堆 JUnit 上运行 PitTest 测试原始程序员使用 Intellij 留在代码中。我在网上找到了这个视频https://www.youtube.com/watch?v=KV5AZ8F7UHs并且一直在尽我所能地跟随。好吧，我找到了一个充满测试用例的示例项目，经过一番头疼后，将 PitTest 添加到 Intellij，构建项目并运行它。请理解我之前从未使用过 Intellij，就在上周了解了 JUnit 测试甚至是什么。我很高兴看到没有发生错误，但是当我打开报告时它是空的。
结果我忘了在“其他参数”部分之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......

沮丧的是，我用谷歌搜索了很长时间，并在这里检查了类似的问题，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所在。该插件在我这边是最新的，PIT Runner似乎也是如此，所以我不知道下一步该做什么。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，或者看起来与我的 InteliJ 上的完全不同。大多数人似乎都在终端或其他地方工作。我并不急于解决这个问题，我有一周的时间去做，但我真的想尽快解决这个问题。这似乎应该是一件容易的事情，但它一直是一个令人头疼的问题。
预先感谢您提供任何信息或指导。
