最近，我决定更新我的 Espresso 代码以使用ActivityScenarioRule已弃用的ActivityTestRule.

为此，我将以下库导入到我的项目中：

最终代码使用ActivityScenarioRule：

package com.realtomjoney.pyxlmoose.activities.main

import androidx.test.espresso.Espresso.onView
import androidx.test.espresso.action.ViewActions
import androidx.test.espresso.matcher.ViewMatchers.*
import com.realtomjoney.pyxlmoose.R
import org.junit.Rule
import org.junit.Test
import androidx.test.espresso.action.ViewActions.click
import androidx.test.espresso.assertion.ViewAssertions
import androidx.test.ext.junit.rules.ActivityScenarioRule
import androidx.test.filters.LargeTest
import androidx.test.internal.runner.junit4.AndroidJUnit4ClassRunner
import org.junit.runner.RunWith


@LargeTest
@RunWith(AndroidJUnit4ClassRunner::class)
class MainActivityTestsWhenNewProjectIsCreated {
    @get:Rule
    var activityTestRule = ActivityScenarioRule(MainActivity::class.java)

    private fun createNewProject() {
        onView(withId(R.id.floatingActionButton)).perform(click())
        onView(withId(R.id.fragmentNewCanvas_projectTitleTextInputEditText)).perform(ViewActions.replaceText("Untitled Project"))
        onView(withId(R.id.fragmentNewCanvas_spanCountTextInputEditText)).perform(ViewActions.replaceText("5"))
        onView(withId(R.id.fragmentNewCanvas_doneButton)).perform(click())
    }

    @Test
    fun uitest_fragmentNewCanvasProjectTitleTextInputEditText_isNotDisplayed_after_fragmentNewCanvasDoneButton_isPressed() {
        createNewProject()
        onView(withId(R.id.fragmentNewCanvas_projectTitleTextInputEditText)).check(ViewAssertions.doesNotExist())
    }

    @Test
    fun uitest_fragmentNewCanvasProjectTitleTextInputLayout_isNotDisplayed_after_fragmentNewCanvasDoneButton_isPressed() {
        createNewProject()
        onView(withId(R.id.fragmentNewCanvas_projectTitleTextInputLayout)).check(ViewAssertions.doesNotExist())
    }

    @Test
    fun uitest_fragmentNewCanvasSpanCountTextInputEditText_isNotDisplayed_after_fragmentNewCanvasDoneButton_isPressed() {
        createNewProject()
        onView(withId(R.id.fragmentNewCanvas_spanCountTextInputEditText)).check(ViewAssertions.doesNotExist())
    }

    @Test
    fun …

大约一个星期前,我问过这个问题

为什么库模块android.support.test在添加依赖项中不可见

经过多次头部刮擦和项目设置变形后,我发现这个app/build.gradle依赖配置让我比以前更进一步,因为至少项目编译但是在尝试运行时没有构建:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'

    defaultConfig {
        applicationId "com.my.package.name"
        minSdkVersion 8
        targetSdkVersion 22
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    sourceSets { main { java.srcDirs = ['src/main/java', 'src/androidTest/java'] } }

    packagingOptions {
        exclude 'LICENSE.txt'
    }

}

dependencies {
    compile 'com.android.support:appcompat-v7:22.1.0'
    compile 'com.android.support:support-v4:22.1.0'
    compile 'com.android.support.test.espresso:espresso-core:2.1'
    compile 'com.android.support.test:testing-support-lib:0.1'
}

请注意,compile而不是androidTestCompile测试支持依赖项.使用androidTestCompile上述问题中提到的问题的结果.

另请注意sourceSets声明中的两个srcDirs.当我手动创建androidTest/java目录时,该声明自动设置.这应该以不同的方式宣布吗

同样,getDefaultProguardFile在ide中用工具提示"无法解析符号'getDefaultProguardFile'"加下划线.如果这是至关重要的.

这种新的启示,切换androidTestCompile到compile,让我相信有什么毛病我成立了项目结构的单元测试的方式.这是我的项目结构图:

我应该提一下,从Eclipse迁移时会自动创建这个项目/模块结构.通过图标装饰,它看起来至少将我的测试类识别为测试类.

但现在我陷入了这个错误:

错误:任务':mymodule:dexDebug'的执行失败.com.android.ide.common.internal.LoggedErrorException:无法运行命令:C:\ …

我正在从机器人切换到浓缩咖啡,我正在使用apk编写测试,我无法访问代码.在使用solo.getView("view-id")的robotium中,我们可以访问视图,但我不知道如何在浓缩咖啡中进行操作？espresso witId()方法需要R.id.viewid,我无权访问.

public class AaEspressoTest {

private static final String LAUNCHER_ACTIVITY_FULL_CLASSNAME = "com.tri.re.CordActivity";
private static Class<?> launcherActivityClass;

static {
    try {
        launcherActivityClass = Class.forName(LAUNCHER_ACTIVITY_FULL_CLASSNAME);
    } catch (ClassNotFoundException e) {
        throw new RuntimeException(e);
    }
}

@Rule
public ActivityTestRule<?> mActivityRule = new ActivityTestRule(launcherActivityClass);


@Test public void testHello() throws Exception{

    onView(withText("Browse older recordings")).perform(click());

   //Id is not accessible shows red
    onView(withId(R.id.button)).perform(click());

}

}

如果一个字符串显示在listAdapter的一个或多个项目中,那么android-espresso是否可以验证？

试着像这样的人:

onData(anything()).inAdapterView(withId(R.id.test)).check(matches(hasToString("Anmeldung steht noch aus!")));

我在检查是否使用浓缩咖啡显示吐司时遇到问题。我正在上课：

       import android.os.IBinder;
    import android.support.test.espresso.Root;
    import android.view.WindowManager;
    import org.hamcrest.Description;
    import org.hamcrest.TypeSafeMatcher;

    public class ToastMatcher extends TypeSafeMatcher<Root> {

    @Override
    public void describeTo(Description description) {
        description.appendText("is toast");
    }

    @Override
    public boolean matchesSafely(Root root) {
        int type = root.getWindowLayoutParams().get().type;
        if ((type == WindowManager.LayoutParams.TYPE_TOAST)) {
            IBinder windowToken = root.getDecorView().getWindowToken();
            IBinder appToken = root.getDecorView().getApplicationWindowToken();
            if (windowToken == appToken) {
                // windowToken == appToken means this window isn't contained by any other windows.
                // if it was a window for an activity, it would have TYPE_BASE_APPLICATION. …

Android Studio 2.1.2

如果用户点击按钮并且用户名为空,我试图让测试失败.这是我的代码.但是,测试总是通过.有没有办法进行测试,如果它EditText是空的,它将失败.

@Test
public void shouldFailToLoginWithEmptyUserName() {
     onView(withId(R.id.btnSignIn)).perform(ViewActions.click());
     onView(withId(R.id.etUsername)).check(ViewAssertions.matches(withText("")));
}

我最近使用espresso对我的android应用程序进行测试。但是有时候测试用例通过了，有时候没有通过。这是一个很长的异步任务，大约需要30秒才能完成。当它失败时，它将抛出此异常：

IdlingResourceTimeoutException

那么，有谁知道为什么会发生这种异常，这种异常的含义是什么？

我有一个异构的回收站视图，我试图将其滚动到位置30处的项目。我的测试通过了，但是我看不到屏幕实际在滚动。

onView(withId(R.id.content_view))
    .perform(RecyclerViewActions.scrollToPosition(30));

这就是我要做的滚动。

这是我的代码：

onView(withId(R.id.first_name)).perform(
                typeText("John"), closeSoftKeyboard());
SystemClock.sleep(5000);
onView(withId(R.id.last_name)).perform(typeText("Smith"));

我从这里尝试了答案 Android：java.lang.SecurityException：注入到另一个应用程序需要INJECT_EVENTS权限 ，但没有帮助。

这是我使用的Expresso版本：

// Android Test Support Libraries
    espressoRunnerVersion = "0.5"
    espressoRulesVersion = "0.5"
    espressoVersion = "2.2.2"

这是完整的堆栈跟踪：

我正在尝试测试android偏好设置，而我对如何实现该结果感到有些困惑。

这是我的偏爱

<PreferenceScreen 
xmlns:android="http://schemas.android.com/apk/res/android">
<ListPreference
    android:id="@+id/numberListPreference"
    android:defaultValue="3"
    android:entries="@array/number_text"
    android:entryValues="@array/number_value"
    android:key="@string/pref_key"
    android:summary="@string/pref_summary"
    android:title="@string/pref_title" />
</PreferenceScreen>

我想测试一下，当我更改显示的ListPreference中的数字时，实际上已更改了SharedPreference。

现在，代码可以正常工作了，我只是阻塞了测试部分。

这是我活动的一部分：

public class SettingActivity extends AppCompatActivity implements
SharedPreferences.OnSharedPreferenceChangeListener {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getFragmentManager()
            .beginTransaction()
            .replace(android.R.id.content, new SettingsFragment())
            .commit();
    }

    public static class SettingsFragment extends PreferenceFragment {
        @Override
        public void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.preferences);
        }
    }
}

问题是我遇到经典的“如果目标视图不属于视图层次结构”错误。

欢迎任何帮助。谢谢 ！
