我正在嘗試爲我的Android應用程序編寫測試測試。當我運行我的測試,和它擊中我的代碼試圖使用com.google.android.gms.vision.face.FaceDetector庫中的部分,測試框架拋出下列錯誤:由於com.google.android.gms.version元數據造成的Android儀器測試錯誤

A required meta-data tag in your app's AndroidManifest.xml does not exist. You must have the following declaration within the <application> element:  <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

然而,我的AndroidManifest.xml已經不包含精確的元數據標籤,就在這裏:

<application 
     android:allowBackup="true" 
     android:hardwareAccelerated="true" 
     android:icon="@drawable/icon" 
     android:label="NeuralEye-FaceID-2" 
     android:theme="@style/Theme.AppCompat" 
     android:largeHeap="true"> 
     <meta-data 
      android:name="com.google.android.gms.version" 
      android:value="@integer/google_play_services_version" /> 
     <meta-data 
      android:name="com.google.android.gms.vision.DEPENDENCIES" 
      android:value="face" /> 

我缺少什麼?我的儀表測試看起來是這樣的:

@RunWith(AndroidJUnit4.class) 
public class FeatureExtractionTest { 


    public FeatureExtraction mFeatureExtraction; 

    public ConcurrentSkipListSet<String> skipList = new ConcurrentSkipListSet(); 

    @Before 
    public void createFeatureExtraction() { 
     mFeatureExtraction = new FeatureExtraction(); 
    } 

    @Test 
    public void testGetFeatures() throws Exception { 
     File file = new File("new.txt"); 
     Context ctx = InstrumentationRegistry.getContext(); 
     mFeatureExtraction.getFeatures(file, skipList, ctx); 
    } 
} 

編輯:添加的build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "22.0.1" 

    defaultConfig { 
     applicationId "tuan.search" 
     minSdkVersion 21 
     targetSdkVersion 23 
     versionCode 1 
     versionName "0.5 " 
     multiDexEnabled true 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile files('libs/opencsv-3.7.jar') 
    compile 'com.android.support:support-v4:23.4.0' 
    compile 'com.google.android.gms:play-services:9.0.1' 
    compile 'com.android.support:design:23.4.0' 
    compile 'org.projectlombok:lombok:1.16.8' 
    compile 'com.android.support:multidex:1.0.0' 
    compile 'org.apache.directory.studio:org.apache.commons.io:2.4' 
    testCompile 'junit:junit:4.12' 
    testCompile 'org.mockito:mockito-core:1.10.19' 
    androidTestCompile 'com.android.support.test:runner:0.4' 
    androidTestCompile 'com.android.support.test:rules:0.4' 
    androidTestCompile 'com.android.support:support-annotations:23.4.0' 
    androidTestCompile 'org.hamcrest:hamcrest-library:1.3' 
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2' 
    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2' 
} 

任何幫助表示讚賞。我已經找到了一大堆SO答案,所有人都說將元數據標籤添加到清單(this one, for example),但是我已經添加了它,並且測試仍然不會通過FaceDetector庫。

請勿添加'google_play_services_version'。它會通過谷歌播放服務AAR自動添加。 –

@JaredBurrows你能澄清一下嗎?我試圖完全刪除標記,並試圖只刪除「android:value」屬性,並在兩個實例中,當測試運行時仍然收到相同的錯誤。 –

顯示build.gradle。 –

發現問題

測試運行方面沒有一個清單文件。我需要將正確的上下文傳遞給我正在測試的方法。我的測試,現在看起來是這樣的(注意互換getTargetContext):

@Test 
public void testGetFeatures() throws Exception { 
    File file = new File("new.txt"); 
    Context ctx = InstrumentationRegistry.getTargetContext(); 
    mFeatureExtraction.getFeatures(file, skipList, ctx); 
} 

FaceDetector能夠被初始化。現在我可以完成實際的測試。希望這有助於某人。

道具爲this random answer,上下文的列表是幫助我的。

不錯,它看起來像你想出來的。 –

是的,謝謝你的幫助@JaredBurrows! –
