Robolectric的新手，首次测试

Question

Hi I'm trying to get into testing using Robolectric. I've set up a button that simply sets another views visibility to visible and I'm trying to test to see if that has occurred. But my test always fails. this is what I have so far:

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class)
public class MyActivityTest {

    private MainAct mActivity;

    @Before
    public void setup() {
        mActivity = Robolectric.buildActivity(MainAct.class).create().get();
    }


    @Test
    public void myActivityAppearsAsExpectedInitially() {
        //mActivity.fab.performClick();

        FloatingActionButton floatingActionButton = (FloatingActionButton) mActivity.findViewById(R.id.fab);
        floatingActionButton.performClick();

        TextView appbar = (TextView) mActivity.findViewById(R.id.searchheader);
        assertThat(appbar).hasText("aidanmack");
    }
}

Unfortunately according to the test, the visibility is still set to "gone".

But that isn't the case when I run the app.

What am I doing wrong?

Robolectric allows you to run tests on the JVM.

The instrumentation test you're trying to run must be performed on a device or emulator using connectedAndroidTest - check out the Espresso framework.
