Android 测试启动画面

Question

所以我有这个运行良好的初始屏幕，但我想测试“处理程序是否已启动下一个 Activity ”。类:

public class SplashActivity extends Activity {
private final int SPLASH_DISPLAY_LENGTH = 3000;
private TextView quote_text;

private int[] quote_id = {R.string.quote_1, R.string.quote_2, R.string.quote_3, R.string.quote_4, R.string.quote_5};


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splashscreen);

    quote_text = (TextView) findViewById(R.id.quote_text);

    int idx = new Random().nextInt(quote_id.length);
    int selectedID = (quote_id[idx]);
    quote_text.setText(getResources().getText(selectedID));

    new Handler().postDelayed(new Runnable() {
         @Override
         public void run() {
             Intent mainIntent = new Intent(SplashActivity.this, MainActivity.class);
             SplashActivity.this.startActivity(mainIntent);
             SplashActivity.this.finish();
         }
     }, SPLASH_DISPLAY_LENGTH);
}  }

机器人电子:测试，在
处失败assertEquals(expectedIntent, shadowOf(activity).getNextStartedActivity());

  @Test
    public void testNextActivityWasLaunchedWithIntent() {
        SplashActivity activity =        Robolectric.buildActivity(SplashActivity.class).create().start().resume().get();
      assertNotNull("MainActivity is not instantiated", activity);

    synchronized (this)
    {
        try {
            this.wait(3200);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    Intent expectedIntent = new Intent(activity, MainActivity.class);
    assertNotNull(expectedIntent);

    assertEquals(expectedIntent,shadowOf(activity).getNextStartedActivity());
}

谁能告诉我，我该如何测试，处理程序是否触发了我的下一个 Activity ？非常感谢!

这可以通过一些流行的单元测试框架来实现，您可以使用它来检查以启动正确的 Intent 。请参阅以下 Robolectric 文档。

http://robolectric.org/writing-a-test/

Intent expectedIntent = new Intent(activity, WelcomeActivity.class);  
assertThat(shadowOf(activity).getNextStartedActivity()).isEqualTo(expectedIntent);
