JUnit test, Unrooted Tests: initializationError
提问by Richard
So I edited the name of a JUnit test and now it wont work. Instead I get Unrooted Tests: initializationError.
所以我编辑了一个 JUnit 测试的名称，现在它不起作用了。相反，我得到了无根测试：初始化错误。
This is a simple test. Infact it is a test for JUnit tests as I am just starting to use it.
这是一个简单的测试。事实上，它是对 JUnit 测试的测试，因为我刚刚开始使用它。
@Test
public void testRun()
String s = null;
assertNull(s);
}
and all i did was change it to testRun2(). Also when I run the file not the individual test, it still runs the old testRun(), not testRun2().
我所做的只是将其更改为 testRun2()。此外，当我运行文件而不是单个测试时，它仍然运行旧的 testRun()，而不是 testRun2()。
My project has Maven not sure if that is a factor. And I have updated the project
我的项目让 Maven 不确定这是否是一个因素。我已经更新了项目

So it turned out that I needed to rebuild using Maven to update the classes. Now it works fine and I can add/modify test cases.
所以结果我需要使用 Maven 重建来更新类。现在它工作正常，我可以添加/修改测试用例。

In my case, i changed the method name and it didn't update it automatically, so the above solution of Project> Clean worked well for me.
就我而言，我更改了方法名称并且它没有自动更新它，因此上面的 Project> Clean 解决方案对我来说效果很好。

Another way this error would occur is forgetting the Test annotation. Encountered when right click method name in Eclipse and Run As -> Junit Test.
发生此错误的另一种方式是忘记 Test 注释。在 Eclipse 中右键单击方法名称并运行为 -> Junit 测试时遇到。
