我想使用 JUnit3 和 UiAutomatorTestCase 类测试 Android 应用程序的 GUI，如 Google 文档中所述。
我在 Eclipse 中创建了一个新的 Android 测试项目，并为其添加了一个非常简单的测试类，它应该按下主页按钮并打开菜单。
import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;
import junit.framework.TestCase;
public class SomeTest extends UiAutomatorTestCase {
public void testDemo() throws UiObjectNotFoundException {
// Simulate a short press on the HOME button.
getUiDevice().pressHome();
// We’re now in the home screen. Next, we want to simulate
// a user bringing up the All Apps screen.
// If you use the uiautomatorviewer tool to capture a snapshot
// of the Home screen, notice that the All Apps button’s
// content-description property has the value “Apps”. We can
// use this property to create a UiSelector to find the button.
UiObject allAppsButton = new UiObject(new UiSelector()
.description("Apps"));
// Simulate a click to bring up the All Apps screen.
allAppsButton.clickAndWaitForNewWindow();
}
}
到目前为止，一切都很好。现在，当我在模拟器上运行此测试时，它会遇到以下错误：

JUnit3 和 UIAutomator 被添加到项目中。我在这里看不到我的错误吗？
