在测试我的 Eclipse 4 RCP 应用程序的退出处理程序时，我面临以下异常。

我的测试用例如下所示

    @RunWith(SWTBotJunit4ClassRunner.class)
public class ExitHandlerTest {

    private static SWTBot bot;

    @BeforeClass
    public static void beforeClass() throws Exception {
        bot = new SWTBot();
    }

    @Test
    public void testExitHandler() {
        SWTBotMenu fileMenu = bot.menu("File");
        Assert.assertNotNull(fileMenu);
        SWTBotMenu exitMenu = fileMenu.menu("Exit");
        Assert.assertNotNull(exitMenu);
        exitMenu.click();
    }

    @AfterClass
    public static void sleep() {
    }

}

我存在的处理程序的代码是

public class ExitHandler {
    @Execute
    public void execute(IWorkbench workbench, EPartService partService, ISaveHandler saveHandler) {
        workbench.close();
    }

}

尽管测试运行良好，但我不确定为什么会出现此异常。

看起来您的测试中包含了 e4 实时模型编辑器，并且您遇到了 Eclipse 错误426373。

我认为这实际上不会影响您的测试，因此您可以忽略它。
