在我的应用程序中，我使用 Kotlin Flow。之前我使用 挂起函数 EspressoIdlingResource.increment()，但它不适用于 Kotlin Flow。如何解决这个问题呢？

我是 Jetpack Compose 测试的新手，并试图弄清楚如何访问 an 的值OutlinedTextField以对它们执行 Instrumentation 测试：

我无法弄清楚访问和检查 EditField 的 SemanticsNode 中的某些值的语法。

我正在使用以下仪器测试：

@Test
fun NameTextField_LongInput_CompleteStatusAndLabelCorrect() {
    composeTestRule.setContent {
        ComposeTemplateTheme {
            NameTextInput(name = "RandomName123", onNameInfoValid = { isComplete = it })
        }
        assertEquals(isComplete, true)

        // This is accessing the label text 
        composeTestRule.onNodeWithText("Name").assertIsDisplayed()
        //How do I access the Editable text?
        //composeTestRule.onNodeWithEditableText("RandomName123") // How do I do something like this?!?!123
    }
}

我想弄清楚如何访问这棵树中的各个项目：

printToLog:
 Printing with useUnmergedTree = 'false'
 Node #1 at (l=0.0, t=110.0, r=1080.0, b=350.0)px
  |-Node #2 at …

我有一个活动,将从额外的东西中获取一个pojo,如下所示:

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

        Bundle extras = getIntent().getExtras();
        if (extras != null)
        {
            MyPojo pojo = extras.getParcelable("pojo");
            // do stuff with my pojo here
            }
        }
        // button that shows a toast message
    }

我很难用Robolectric进行测试,我相信我需要使用ShadowIntents和ShadowActivities的组合,但是文档有点薄,而且关于这个特定场景的任何有用的教程都相当稀疏.

这是我到目前为止所提出的:

@Test
    public void assertClickingTagSightingDisplaysToast()
    {
        myActivity = new MyActivity();
        myActivity.onCreate(null);
        ShadowActivity shadowMyActivity = shadowOf(myActivity);
        shadowMyActivity.setIntent(new Intent().putExtra("pojo", generateAPojo()));


        ShadowButton shadowButton = (ShadowButton) shadowOf(shadowMyActivity.findViewById(R.id.myButton));
        shadowButton.performClick();

        assertThat(ShadowToast.getTextOfLatestToast(), equalTo("Button was clicked!"));
    }

当我执行这些测试时,我一直得到一个空指针,在getIntent().getExtras()我的活动中,我假设我用意图模拟活动的过程是不正确的.

有人可以帮忙吗？

谢谢

我目前正在为我的项目实现Android的Fest,但我似乎遇到了依赖问题.如果我在没有包含Fest库的情况下运行测试,测试将正常运行.一旦我添加了Fest库,那么测试就不再运行了.而是抛出异常.

我的项目使用以下依赖项:

compile files('libs/robotium-solo-5.1.jar')
androidTestCompile 'com.squareup:fest-android:1.0.8'
androidTestCompile 'com.google.code.gson:gson:2.2.4'
androidTestCompile 'com.jayway.android.robotium:robotium-solo:5.1'
androidTestCompile 'com.google.mockwebserver:mockwebserver:20130706'
androidTestCompile 'com.google.dexmaker:dexmaker:1.0'
androidTestCompile('com.google.dexmaker:dexmaker-mockito:1.0') {
    exclude module: 'hamcrest-core'
    exclude module: 'objenesis'
    exclude module: 'mockito-core'
}
androidTestCompile 'org.mockito:mockito-all:+'

我已经尝试排除我在下面列出的Fest Android依赖项,但它对测试的运行没有影响.

androidTestCompile ('com.squareup:fest-android:1.0.8') {
    exclude group: 'com.google.android', module: 'android'
    exclude group: 'com.google.android', module: 'support-v4'
    exclude group: 'org.easytesting', module: 'fest-assert-core'
}

这是在包含Fest库的情况下运行测试时发生的异常.

我在使用mockito在我的android应用程序中测试我的presenter类时遇到了一些奇怪的行为.

即使它通过我的设备,我的测试也会失败.行为不端的代码:

@Test
public void testValidPhoneNumber() throws Exception {
    String phone = "0123456789";
    assert(TextUtils.isDigitsOnly(phone));
}

以上错误导致以下错误:

Process finished with exit code 255

当我添加依赖项时:

compile 'net.bytebuddy:byte-buddy-android:0.7.8'

在我的应用程序中,我收到此错误:

Conflict with dependency 'net.bytebuddy:byte-buddy'. Resolved versions for app (0.7.8) and test app (0.6.14) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

我访问了http://g.co/androidstudio/app-test-app-conflict,它说:

如果主APK和测试APK使用相同的库(例如Guava)但是在不同的版本中,Gradle构建将失败.[...]为了使构建成功,只需确保两个APK使用相同的版本

但我不知道这意味着什么.

你能帮助我吗？谢谢.

我需要测试我的自定义视图的状态是否正确保存在活动重新创建上.

我该如何测试呢？可以用Espresso进行测试吗？

因此，我最近开始在我现有的Android项目之一中搞混Espresso。

一切都进行得很顺利，直到我开始AutoCompleteTextView在程序中找到它。我似乎不明白如何正确单击自动完成列表中的第一件事。实际上，我甚至不能确定使用哪个，onView()或者onData()在这种情况下。

在我的应用程序中，我在一个活动中附加了两个片段。每个片段包含不同的视图。

第一个具有两个编辑文本字段和两个按钮，用户可以在其中登录或注册。所以现在我想进行一些Espresso测试。

@RunWith(AndroidJUnit4.class)
public class LoginTest {
@Rule
public final ActivityRule<MainActivity> main = new ActivityRule<>   
(MainActivity.class);

@Test
public void shouldBeAbleToFindViewsOfLoginScreen(){
    onView(withText(R.id.user_name)).perform(click());
   }

 }

但是，测试抱怨它找不到ID为R.id.user_name的视图。

android.support.test.espresso.NoMatchingViewException: No views in hierarchy    
found matching: with string from resource id: <2131493050>[user_name] value:    
false

我也使用了从uiautomatorviewer检查的相应ID。

该片段的xml代码是

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
