使用Robotium - Android检查片段是否存在

import com.jayway.android.robotium.solo.Solo;
import android.test.ActivityInstrumentationTestCase2;

public class TestFragment extends ActivityInstrumentationTestCase2<MainActivity> {
    private Solo solo;

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

    @Override
    protected void setUp() throws Exception {
        solo = new Solo(getInstrumentation(), getActivity());
    }

    @Override
    public void tearDown() throws Exception {
        solo.finishOpenedActivities();
    }

    public void testFragmentExists() {
        // 等待片段出现
        solo.waitForFragmentById(android.R.id.content, "my_fragment");

        // 断言片段存在
        assertTrue(solo.searchText("My Fragment"));
    }
}
