Question

我正在尝试在Android测试框架中编写此测试以在模拟器上运行，因为出于某些兼容性原因我无法在我的项目中使用robolectric。

如何切换以及我使用什么（ActivityInstrumentationTestCase2, ActivityTestCase）？
也许是一些例子？

我正在尝试从此project转换测试，这是代码

package com.swanson.octodroid.test;
import java.util.ArrayList;
import java.util.List;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.ArgumentCaptor;
import org.mockito.Captor;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.robolectric.Robolectric;
import org.robolectric.shadows.ShadowToast;
import org.robolectric.util.ActivityController;

import retrofit.Callback;

import com.swanson.octodroid.GitHub;
import com.swanson.octodroid.MainActivity;
import com.swanson.octodroid.Owner;
import com.swanson.octodroid.Repository;

import static org.fest.assertions.api.Assertions.assertThat; 
import static org.fest.assertions.api.ANDROID.assertThat; 

@RunWith(CustomTestRunner.class)
public class MainActivityTest {

    private MainActivity activity;

    @Mock
    private GitHub mockApi;

    @Captor
    private ArgumentCaptor<Callback<List<Repository>>> cb;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);

        ActivityController<MainActivity> controller = Robolectric.buildActivity(MainActivity.class);
        activity = controller.get();
        activity.setApi(mockApi);

        controller.create();
    }

    @Test
    public void shouldFillAdapterWithReposFromApi() throws Exception {
        Mockito.verify(mockApi).repositories(Mockito.anyString(), cb.capture());

        List<Repository> testRepos = new ArrayList<Repository>();
        testRepos.add(new Repository("rails", "ruby", new Owner("dhh")));
        testRepos.add(new Repository("android", "java", new Owner("google")));

        cb.getValue().success(testRepos, null);

        assertThat(activity.getListAdapter()).hasCount(2);
    }

    @Test
    public void shouldToastSadMessageIfNoRepos() throws Exception {
        Mockito.verify(mockApi).repositories(Mockito.anyString(), cb.capture());

        List<Repository> noRepos = new ArrayList<Repository>();

        cb.getValue().success(noRepos, null);

        assertThat(ShadowToast.getTextOfLatestToast()).contains("No repos :(");
        assertThat(activity.getListAdapter()).isEmpty();
    }

    @Test
    public void shouldToastIfApiError() throws Exception {
        Mockito.verify(mockApi).repositories(Mockito.anyString(), cb.capture());

        cb.getValue().failure(null);

        assertThat(ShadowToast.getTextOfLatestToast()).contains("Failed");
    }

}
