通过命令行启动java测试
我创建了 runner.bat 来启动一个 java 测试 它包含：java路径，类路径org.junit.runner.JUnitCore package.class 当我启动它时：
失败测试运行：1，失败：1

I created runner.bat to launch one java test
it contains : path to java,classpath org.junit.runner.JUnitCore package.class
when I launch it :
FAILURES Tests run: 1, Failures: 1

如果调用该方法时 JVM 已经关闭，则 Runtime.addShutdownHooks() 将抛出 IllegalStateException。
是否有什么原因导致您的测试在 CompositePanel 构建完成之前结束？ （例如，在单独的线程中运行的东西。）
Runtime.addShutdownHooks() will throw an IllegalStateException if the JVM is already shutting down when the method is called.
Could something be causing your test to end before the construction of your CompositePanel has completed? (e.g. something running in a separate thread.)
