EclEmma "Coverage As" Eclipse JUnit 线程死亡
EclEmma "Coverage As" Eclipse JUnit Thread Death
我使用 TestFX 编写了以下 JUnit4 测试来测试特定产品（待办事项列表）的 GUI (JavaFX)，以及两个必要的 classes。第一个 class 是管理整个 GUI 的主要 class，而第二个是用于文本字段的 class。如有必要，完整的源代码位于 here（它是已经提交的学校项目的一部分）。
如果我只是 运行 使用 Eclipse 中的 F11 热键或 "Run As -> JUnit Test"，测试将完全正常。但是，当我 select "Coverage" 时，它会在第一个测试用例上出现错误（无论我选择将哪个设置为第一个）。具体来说，它 "types" 第一个测试用例的前两个字符（这里的示例用例中为 sh），然后给我检测到用户输入的错误 ([TestFX] User mouse movement detected. Aborting test.) 然后它移至下一个测试用例。
我一直无法自己弄清楚，而且我似乎无法在网上找到太多关于这方面的帮助。任何帮助将不胜感激！根据堆栈跟踪，它看起来与线程有关，但我看不出覆盖率 运行ning 将如何导致这种情况（当正常测试没有时）。
我不得不缩短堆栈跟踪，因为我达到了极限。

P.S。对不起，如果我添加了不必要的标签。不确定我应该包括什么。
P.P.S。我从来没有让测试文件中的断言完全起作用。如果你愿意，你可以忽略它们，因为我不想学习如何解决这个问题（现在）。
您的线程被外部源中断（停止），异常被抛出，同时也中断了测试。抓住它，忽略它。
try {
Thread.sleep(7000);
}
catch (InterruptedException e) {}
一个好的测试应该是快速的，并且不依赖于外部事件或 类（您正在测试的除外）。也许你应该尝试做更小、更有针对性的测试。
由于 GUI 在其自己的线程内工作，因此您自己的 JUnit 测试结束会终止它。确保正确关闭 GUI。
我使用 TestFX 编写了以下 JUnit4 测试来测试特定产品（待办事项列表）的 GUI (JavaFX)，以及两个必要的 classes。第一个 class 是管理整个 GUI 的主要 class，而第二个是用于文本字段的 class。如有必要，完整的源代码位于 here（它是已经提交的学校项目的一部分）。

P.S。对不起，如果我添加了不必要的标签。不确定我应该包括什么。
P.P.S。我从来没有让测试文件中的断言完全起作用。如果你愿意，你可以忽略它们，因为我不想学习如何解决这个问题（现在）。
您的线程被外部源中断（停止），异常被抛出，同时也中断了测试。抓住它，忽略它。
try {
Thread.sleep(7000);
}
catch (InterruptedException e) {}
一个好的测试应该是快速的，并且不依赖于外部事件或 类（您正在测试的除外）。也许你应该尝试做更小、更有针对性的测试。
由于 GUI 在其自己的线程内工作，因此您自己的 JUnit 测试结束会终止它。确保正确关闭 GUI。
