java - SWTBot 在单击时挂起

Question

我正在尝试使用 SwtBot 2.2.1 自动化一个简单的新项目向导。该代码是我在教程中找到的代码

bot.menu("File").menu("New").menu("Project...").click();

问题是 click() 方法调用永远不会返回。我的目标平台是 Linux x86_64 上的 Eclipse Kepler 。然而，新项目对话框被打开，所以我不确定为什么调用没有返回。这是测试挂起时测试中的 Eclipse 实例的屏幕截图

主线程的堆栈跟踪是

如何才能使测试成功运行？

Answer 1

我的错误是在 UI 线程上启动测试。一旦我在启动配置中取消选中“在 UI 线程上运行”，测试就可以正常执行。
