我正在尝试运行我的第一个 android 测试

    import android.content.Intent;
import android.test.ActivityUnitTestCase;
import android.test.suitebuilder.annotation.SmallTest;
import android.widget.Button;

import com.lenabru.activities.MainActivity;

/**
 * @author Lena Sep 16, 2013, 2013 at 10:02:19 PM
 */
public class MainActivityUnitTest extends ActivityUnitTestCase<MainActivity> {

    MainActivity activity;
    int buttonId;

    public MainActivityUnitTest() {
        super(MainActivity.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        Intent intent = new Intent(getInstrumentation().getTargetContext(), MainActivity.class);
        startActivity(intent, null, null);
        activity = getActivity();
    }

    @SmallTest
    public void testLayout() {

        buttonId = com.lenabru.R.id.btnLogin;
        assertNotNull(activity.findViewById(buttonId));
        Button view = (Button) activity.findViewById(buttonId);
        assertEquals("Incorrect label of the button", "Start", view.getText());
    }


    @Override
    protected void tearDown() throws Exception {

        super.tearDown();
    }
}

但是，我得到了这个例外

确保您的应用程序项目位于您的测试项目构建路径中。

IntelliJ 在使用 ActionBar 支持时会出现类似的问题。解决此问题的方法是将 v4 和 v7 支持库添加为“提供”范围，而不是“编译”到测试模块。
