android – Espresso如何等待一段时间(1小时)？

在我的测试用例中,我必须记录1小时,在机器人solo.sleep(600000)完成了我的工作,但在espresso我感到困惑IdlingResource的概念.我必须开始录音并等待一段时间(取决于测试的类型)15分钟,60分钟等

机器人中的等效代码

solo.clickOnView(solo.getView("start_record"));
    solo.sleep(duration * 60 * 1000);
    solo.clickOnView(solo.getView("stop_record"));

我尝试在espresso中使用它

@RunWith(AndroidJUnit4.class)
@SmallTest
public class AaEspressoTest {

private static final String LAUNCHER_ACTIVITY_FULL_CLASSNAME = "com.absd.rec.RecorderActivity";
private static Class<?> launcherActivityClass;
private Solo solo;
private static CoreRecordingTest skyroTestRunner;


private static Class<? extends Activity> activityClass;

static {
    try {
        activityClass = (Class<? extends Activity>) Class.forName(LAUNCHER_ACTIVITY_FULL_CLASSNAME);
    } catch (ClassNotFoundException e) {
        throw new RuntimeException(e);
    }
}

@Rule
public final ActivityTestRule<?> activityRule
        = new ActivityTestRule<>(activityClass);

private IntentServiceIdlingResource idlingResource;

@Before
public void registerIntentServiceIdlingResource() {
    Instrumentation instrumentation = InstrumentationRegistry.getInstrumentation();
    idlingResource = new IntentServiceIdlingResource(instrumentation.getTargetContext());
    Espresso.registerIdlingResources(idlingResource);
}

@After
public void unregisterIntentServiceIdlingResource() {
    Espresso.unregisterIdlingResources(idlingResource);
}

@Test
public void testHello() throws Exception {

 onView(withId(AaEspressoTest.getId("recorderpage_record"))).perform(click());

    registerIntentServiceIdlingResource();

    onView(withId(AaEspressoTest.getId("recorderpage_stop"))).perform(click());

   }
}

空闲资源

public class IntentServiceIdlingResource implements IdlingResource {
private final Context context;
private ResourceCallback resourceCallback;
public static boolean status = false;

public IntentServiceIdlingResource(Context context) {
    this.context = context;
}

@Override
public String getName() {
    return IntentServiceIdlingResource.class.getName();
}

@Override
public boolean isIdleNow() {
    return getTimer();
}

@Override
public void registerIdleTransitionCallback(ResourceCallback resourceCallback) {
    this.resourceCallback = resourceCallback;

}

private static boolean getTimer() {

    new CountDownTimer(5000,1000) {
        @Override
        public void onTick(long millisUntilFinished) {
            // Do nothing
            status = false;
        }

        @Override
        public void onFinish() {             
            status = true;
        }
    };
    return status;
}
}

例外：

android.support.test.espresso.IdlingResourceTimeoutException: Wait for [com.adbs.recorder.IntentServiceIdlingResource] to become idle timed out

解决方法

您需要一个具有isIdleNow()的IdlingResource,只有在特定的时间量过去时才返回true.为了达到这个目的,保存开始时间并与当前时间进行比较：

public class elapsedtimeIdlingResource implements IdlingResource {
  private final long startTime;
  private final long waitingTime;
  private ResourceCallback resourceCallback;

  public elapsedtimeIdlingResource(long waitingTime) {
    this.startTime = System.currentTimeMillis();
    this.waitingTime = waitingTime;
  }

  @Override
  public String getName() {
    return elapsedtimeIdlingResource.class.getName() + ":" + waitingTime;
  }

  @Override
  public boolean isIdleNow() {
    long elapsed = System.currentTimeMillis() - startTime;
    boolean idle = (elapsed >= waitingTime);
    if (idle) {
      resourceCallback.onTransitionToIdle();
    }
    return idle;
  }

  @Override
  public void registerIdleTransitionCallback(
      ResourceCallback resourceCallback) {
    this.resourceCallback = resourceCallback;
  }
}

在测试中创建并注册此空闲资源：

@Test
public static void waitForOneHour() {
  long waitingTime = DateUtils.HOUR_IN_MILLIS;

  // Start
  onView(withId(AaEspressoTest.getId("recorderpage_record")))
      .perform(click());

  // Make sure Espresso does not time out
  IdlingPolicies.setMasterPolicyTimeout(
      waitingTime * 2,TimeUnit.MILLISECONDS);
  IdlingPolicies.setIdlingResourceTimeout(
      waitingTime * 2,TimeUnit.MILLISECONDS);

  // Now we wait
  IdlingResource idlingResource = new elapsedtimeIdlingResource(waitingTime);
  Espresso.registerIdlingResources(idlingResource);

  // Stop
  onView(withId(AaEspressoTest.getId("recorderpage_stop")))
      .perform(click());

  // Clean up
  Espresso.unregisterIdlingResources(idlingResource);
}

您需要setMasterPolicyTimeout和setIdlingResourceTimeout调用,以确保Espresso由于超时而不会终止测试.
