控制自动化测试何时结束 – Espresso: 我正在测试一个不寻常的情况。我正在使用Espresso来编写我的测试。我知道Espresso和InstrumentationTestCase不是为了做到这一点。我有一个我在其中一个课程中创建的监听器，它会通知我某个值的变化。我在我的测试套件中使用了监听器。当我从侦听器获取值时，我需要声明值已更改为此类。我的问题是测试将在我收到监听器的值之前结束。 private void sendSpeedChanges() { setStaticSpeed(new Random().nextInt(10) + 2); try { runTestOnUiThread(new Runnable() { @Override public void run() { consoleActivity.onSpeedChanged(getStaticSpeed(), false); } }); } catch (Throwable throwable) { throwable.printStackTrace(); } } private void createSpeedDelegate() { EspressoMachineValues.setOnSpeedChangeListener(new EspressoMachineValues.OnSpeedChangeListener() { @Override public void onSpeedChanged(double speed) { //assert speed is correct. assertTrue(getStaticSpeed() […]

Espresso onData在视图上执行“加载适配器数据”时出错: 我有一个应用程序，有ListView，我想找到LinearLayout，id = order_untake_jijia_listview_jia 代码是： onData(withClassName(endsWith(“ListView”))) .inAdapterView(allOf(withId(R.id.order_untake_jijia_listview_ll), hasSibling(withText(“9.0”)))) .atPosition(0).onChildView(withId(R.id.order_untake_jijia_listview_jia)); dataInteraction.perform(ViewActions.click()); 但我有错误： Error performing ‘load adapter data’ on view ‘(with id: com.edaixi:id/order_untake_jijia_listview_ll and has sibling: with text: is “9.0”)’. Caused by: java.lang.RuntimeException: Action will not be performed because the target view does not match one or more of the following constraints: (is assignable from class: class android.widget.AdapterView […]

预validation类中的Android错误类ref解析为意外实现: 我在Android Espresso测试中遇到过这个问题。但是这在运行/编译时运行良好。我知道这个错误有几个线程，但我找不到符合我情况的修复程序。我目前正在处理一个 “java.lang.IllegalAccessError：预validation类中的类ref解析为意外实现”。我已经添加了 androidTestCompile(‘com.android.support.test.espresso:espresso-contrib:2.2’) { exclude group: ‘com.android.support’, module: ‘support-v4’ } 但它仍然无法正常工作。有人可以帮我解决这个问题。谢谢。这是我的依赖 dependencies { compile fileTree(dir: ‘libs’, include: [‘*.jar’]) /*Android Testing*/ androidTestCompile ‘com.android.support.test:runner:0.3’ androidTestCompile ‘com.android.support.test:rules:0.3’ androidTestCompile ‘com.android.support.test.espresso:espresso-core:2.2’ androidTestCompile ‘com.android.support.test.espresso:espresso-idling-resource:2.2.1’ androidTestCompile ‘com.android.support:support-annotations:23.0.1’ androidTestCompile(‘com.android.support.test.espresso:espresso-contrib:2.2’) { exclude group: ‘com.android.support’, module: ‘support-v4’ } compile ‘com.google.android.gms:play-services:8.3.0’ compile ‘com.android.support:support-v4:23.0.+’ compile ‘com.android.support:appcompat-v7:23.0.1’ compile ‘com.mcxiaoke.volley:library:1.0.18’ compile […]

浓咖啡：选择后为什么纺纱厂不关门？: 我有一个关于在Spinners with Espresso中选择商品的问题。或者更确切地说：选择有效，但之后视图断言失败，因为微调器仍处于打开状态。假设我有一个非常简单的活动，其中包含一个微调器和一个显示选择的textview，如下所示：现在，我写了一个Espresso测试，选择’狗’并validationtextview是否相应更新： @Test public void selectDogs() throws Exception { onData(allOf(is(instanceOf(String.class)), is(“dogs”))) .inAdapterView(withId(R.id.spinner)) .perform(click()); onView(withId(R.id.selected)).check(matches(withText(“dogs”))); } 该测试失败，因为onData()…perform(click()); 没有关闭旋转器，它只是让它打开。通过调试validation：例外是： android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: org.flinc.app:id/selected If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one […]

在Dalvik运行时设备上运行Espresso仪器测试的问题: 我遇到类似的问题， FragmentActivity无法通过ActivityInstrumentationTestCase2进行测试顶级解决方案存在的问题仅适用于使用Eclipse构建系统。我正在使用Gradle作为我的项目。在运行ART运行时的Nexus 5上，我的Espresso仪器测试运行完美。当我在Dalvik运行时或模拟器上使用Nexus 4时，我遇到了在测试框架之外运行应用程序时不会发生的exception。 java.lang.NoClassDefFoundError: com.packagename.fragment.ProgressDialogFragment 在日志中，我发现这些可疑消息类似于链接的问题： Class resolved by unexpected DEX: Landroid/support/v4/app/DialogFragment2;(0x41e969d8):0x76064000 ref [Landroid/support/v4/app/DialogFragment;] Landroid/support/v4/app/DialogFragment;(0x41e969d8):0x75883000 (Landroid/support/v4/app/DialogFragment2; had used a different Landroid/support/v4/app/DialogFragment; during pre-verification) Unable to resolve superclass of Landroid/support/v4/app/DialogFragment2; (271) Link of class ‘Landroid/support/v4/app/DialogFragment2;’ failed Unable to resolve superclass of Lcom/packagename/fragment/ProgressDialogFragment; (270) Link of class ‘Lcom/packagename/fragment/ProgressDialogFragment;’ failed Could not find […]

第二个活动上的单击按钮在视图上执行“单击”或“滚动到”时出错: 单击Espresso测试中的按钮会出现问题。假设我有两个活动“Activity1”和“Activity2”。单击Activity1中的对话框确定按钮启动Activity2，其中无法单击Activity2中的按钮。 // The current activity in testing // ….. onView(withText(R.string.dialog_btn_ok)).perform(click()); // go to the second activity // The button on the second activity onView(withId(R.id.btnMP)).check(matches(isDisplayed())); // this is ok onView(withId(R.id.btnMP)).perform(click()); // got error here android.support.test.espresso.PerformException：在视图’上执行’单击’时出错，ID为：………. 引发者：java.lang.RuntimeException：将不执行操作，因为目标视图与以下一个或多个约束不匹配：至少90％的视图区域显示给用户。目标视图：“按钮{id = 2131296390，res-name = btnMP，visibility = VISIBLE，width = 652，height = 160，has-focus = false，has-focusable = true，has-window-focus = true，is- clickable […]
