测试Eclipse插件的启动配置委托

Question

我想测试我的LaunchConfigurationDelegate，但是我无法模拟启动方法的eclipse类。我正在使用Mockito，当我运行测试时，我得到ILaunchConfiguration模拟的NoClassDefFoundError。测试看起来像这样

@Test
public void testLaunch() {
    ILaunchConfiguration config = mock(ILaunchConfiguration.class);
    ILaunch launch = mock(ILaunch.class);
    IProgressMonitor monitor = mock(IProgressMonitor.class);
    MyLaunchConfigurationDelegate launchDelegate = new MyLaunchConfigurationDelegate();

    try {
        launchDelegate.launch(config, "run", launch, monitor);
    } catch (CoreException e) {
        fail(e.getMessage());
    }
}

如何测试启动器？
