我尝试过使用Espresso测试框架并编写了一个简单的测试.

没有什么花哨的,只有这个代码:

onView(withId(R.id.login_button_stub)).perform(click());

测试在Nexus 5设备和Genymotion与Android 5.0上运行良好,但在Android Emulator 4.x,5.0,Genymotion 2.3,4.x和LG G2与Android 4.x上运行失败.

在所有这些设备/模拟器/模拟器上,单击按钮并执行其操作(在我的情况下转到另一个屏幕).问题是它阻塞了perform某些设备.这在60秒后以一个很好的例外结束:

android.support.test.espresso.PerformException: Error performing 'single click' on view 'with id: com.vielengames.mock:id/login_button_stub'.
    ...
    Caused by: android.support.test.espresso.AppNotIdleException: Looped for 3544 iterations over 60 SECONDS. The following Idle Conditions failed .
    ...

请注意,没有关于哪些条件失败的信息.查看Espresso源代码,应该有一个以逗号分隔的问题列表.

这是完整的代码:TestCase.java.

和完整的堆栈跟踪:

当我在运行一些espresso测试时显示的布局中有ProgressBar时,我会遇到:

Caused by: android.support.test.espresso.AppNotIdleException: Looped for 1670 iterations over 60 SECONDS. The following Idle Conditions failed .

解决这个问题的好方法是什么？找到一些hackish东西,但寻找一个很好的方式

@Test
    public void test3_PaySuccessful(){
        init();

    ViewInteraction amountEditText = onView(
            allOf(withId(R.id.et_amount), isDisplayed()));
    amountEditText.perform(replaceText("SGD 0.010"), closeSoftKeyboard());

    //, withText("Proceed")
    ViewInteraction appCompatButton = onView(
            allOf(withId(R.id.btn_confirm), isDisplayed()));
    appCompatButton.perform(click());

    //, withText("Pay")
    ViewInteraction appCompatButton2 = onView(
            allOf(withId(R.id.btn_confirm), isDisplayed()));
    appCompatButton2.perform(click());

    //dialog
    ViewInteraction appCompatButton3 = onView(
            allOf(withId(R.id.confirm_button), withText("Confirm"), isDisplayed()));
    appCompatButton3.perform(click());

    //have to disable animation in order to pass this.
    intended(CoreMatchers.allOf(hasComponent(PaymentSelectionActivity2.class.getName())));

}

我在使用涉及动画的视图进行Espresso测试时遇到了一个问题,我知道Espresso无法处理动画,所以我在下面做了. - 禁用我的测试设备窗口动画,过渡动画和动画设计持续时间缩放都设置为OFF(这不起作用) - 然后我尝试在我的代码中添加一个标志,例如.espresso_testing = true.如果为true,我的代码将跳过调用所有startAnimation()函数调用.--->这是有效的.但是,在编写espresso测试用例时,我无法更改应用程序中的代码.包括上面的测试用例.

有没有其他方法可以做到这一点？提前致谢.

我有一个视图,其中一个元素在无限循环中使用以下动画进行动画处理:

<translate
    android:fromXDelta="0%"
    android:toXDelta="100%"
    android:duration="10000"
    android:repeatCount="-1"
    android:repeatMode="reverse"/>

当Espresso打开我的活动时,它可以执行一些操作但很快冻结.我想Espresso正在等待UI线程变为空闲,在这种情况下永远不会发生.

是我测试此视图以实现禁用动画的机制的唯一方法吗？我可以有另一个类处理动画,这将被模拟为测试.或者建立时间条件.

编辑:我还没有创建一个示例项目来尝试重新创建该问题,但在此期间还有一些进一步的细节:

1)我正在使用Jake Wharton ActivityRule自动启动我的活动(https://gist.github.com/JakeWharton/1c2f2cadab2ddd97f9fb).

2)这是我的测试:

onView(withId(R.id.btn_yes)).perform(click());

3)这是完整的堆栈跟踪.注意AppNotIdleException:

我正在使用Junit4和Espresso进行测试.我正面临一个与espresso测试相关的奇怪问题 - 当我调用onView时,有时一切都按照它应该执行,但有时候我的测试会冻结,60秒后我得到类似这样的东西"android.support.test.espresso.AppNotIdleException:Looped超过60秒的63次迭代.以下空闲条件失败ASYNC_TASKS_HAVE_IDLED"例如:

    onView(withId(R.id.zone_button_continue)).perform(click());
    onView(withId(R.id.loginButton)).check(matches(isDisplayed()));
    onView(withId(R.id.number)).check(matches(isDisplayed()));
    onView(withId(R.id.password)).check(matches(isDisplayed()));
    onView(withId(R.id.number)).perform(typeText(phoneNumber));
    onView(withId(R.id.password)).perform(typeText(password));
    onView(withId(R.id.loginButton)).perform(click());

一切都得到了正确执行,除了最后一行 - 由于某种原因,它找不到loginButton,但它有100%的百分比.我可以

activity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            activity.findViewById(R.id.loginButton).performClick();
             }
    });

这很有效.在我的大多数活动中我都遇到过类似的问题 - 有时onView工作有时候没有.

什么可能导致这种不一致？我一直在与这个问题作斗争,这让我的测试非常令人沮丧和困难.我的结论到目前为止我的gradle依赖项出了问题,或者我的应用程序中存在某种阻止espresso正常工作的错误.但奇怪的是,在上面的例子中,onView的所有内容都在工作,除了最后一行,一切都发生在一个活动中,这让我怀疑这个bug是在我的应用程序中.这是我的gradle依赖项:

我实际上尝试用Espresso设置一些单元测试,经过几个小时的研究,应用程序只做了点击并通过EditText获得焦点,但之后没有任何内容

Caused by: android.support.test.espresso.AppNotIdleException: Looped for 1996 iterations over 60 SECONDS. The following Idle Conditions failed .

我删除了所有动画和SwipeRefreshLayout因为我看到swiperefresh有一个错误

我实际上使用一些回调来替换Activity中的当前片段

如果有人有一些提示,我会在搜索u_u 4小时后离开

谢谢 :)

我的Gradle依赖项:

// App dependencies
compile 'com.android.support:support-annotations:23.3.0'

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.2'

我在defaultConfig上添加了这个:

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

有我的测试:

@RunWith(AndroidJUnit4.class)
@LargeTest
public class HelloWorldEspressoTest {

    public static final String USERNAME = "do_f"; …

当我登陆页面时,我不断收到此错误.有什么可以解决这个问题？
