Robolectric與ActiveAndroid安裝nullpointerexception ActiveAndroid $ ReflectionUtils

我想在現有的應用程序中實現robolectric測試。我可以運行簡單的靜態測試，但是當我使用ActiveAndroid添加測試時，我得到NullPointerExceptions，我認爲單元測試運行時找不到ActiveAndroid。

我不確定也許有一些ActiveAndroid的Robelectric單元測試配置。請幫助我解決這個問題。

這是項目結構：

MainApp
-src /主
-src /測試

爲LibraryApp
-src /主/型號< ---這裏有我的模型和類爲主動android
-libs/activeandroid-3.0.jar < ----活動的android jar文件

我在Library App中導入了ActiveAndroid-3.0.jar。

這裏是的build.gradle文件：

MainApp的build.gradle

android { 
compileSdkVersion 21 
buildToolsVersion "22.0.0" 

defaultConfig { 
    applicationId "com....." 
    minSdkVersion 18 
    targetSdkVersion 21 
    versionCode 1 
    versionName "1.0" 

    // Enabling multidex support. 
    multiDexEnabled true 

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
} 
buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 

dexOptions { 
    preDexLibraries = false 
} 

sourceSets { 
    main { 
     java { 
      exclude 'com/google/gson/annotations/Expose.class' 
     } 
    } 
} 

lintOptions{ 
    abortOnError false 
} 
packagingOptions{ 
    exclude 'META-INF/NOTICE.txt' 
    exclude 'META-INF/LICENSE.txt' 
} 
}

} 
testCompile "org.robolectric:robolectric:3.0-rc3" 
testCompile 'junit:junit:4.12' 
testCompile "org.robolectric:shadows-multidex:3.0" 
}

爲LibraryApp的build.gradle

apply plugin: 'com.android.library' 

android { 
compileSdkVersion 21 
buildToolsVersion "22.0.0" 

defaultConfig { 
    minSdkVersion 18 
    targetSdkVersion 22 
    versionCode 1 
    versionName "1.0" 

    // Enabling multidex support. 
    multiDexEnabled false 
} 
buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 
dexOptions { 
    preDexLibraries = false 
} 

packagingOptions{ 
    exclude 'META-INF/NOTICE.txt' 
    exclude 'META-INF/LICENSE.txt' 
    exclude 'META-INF/LICENSE' 
    exclude 'META-INF/NOTICE' 
} 

configure(android.lintOptions) { 
    abortOnError false 
} 
} 

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 

compile 'com.balysv.materialmenu:material-menu-toolbar:1.5.4' 
compile 'org.lucasr.twowayview:twowayview:0.1.4' 
compile files('libs/gson-2.3.1.jar') 
compile 'org.apache.httpcomponents:httpmime:4.2.3' 
compile files('libs/activeandroid-3.0.jar') 
compile 'com.google.code.gson:gson:2.3.1' 
compile 'com.squareup.picasso:picasso:2.5.2' 
compile 'com.scottyab:aescrypt:0.0.1' 
compile 'com.android.support:multidex:1.0.1' 

testCompile "org.robolectric:robolectric:3.0-rc3" 
testCompile 'junit:junit:4.12' 
testCompile "org.robolectric:shadows-multidex:3.0" 
}

這裏是我的單元測試，

@RunWith(RobolectricGradleTestRunner.class) 
@Config(constants = BuildConfig.class, sdk = Build.VERSION_CODES.LOLLIPOP, shadows= {ShadowMultiDex.class}) 
public class MyActivityTest { 
    Activity activity = null; 
    @Before 
    public void init(){ 
    } 
    @Test 
    public void getMillisecondFromHourTest(){ 
    } 
}

如果我使用自定義Application類運行單元測試，其中ActiveAndroid.initialize（this）;哪裏沒有被稱爲我的單元測試運行（只有那些靜態斷言）。

如果我使用應用程序類的調用ActiveAndroid.initialize（this）;發生這種情況：

順便說一句。我在我的MyApplication.class中也有這個

@Override 
protected void attachBaseContext(Context base) { 
    super.attachBaseContext(base); 
    MultiDex.install(this); 
}

啊，我們有類似的問題。我們解決了它在明年Robolectric功能http://robolectric.org/custom-test-runner/

我們提出創建方法：

@Override 
protected void attachBaseContext(Context base) { 
    super.attachBaseContext(base); 
    installMultiDex(); 
} 

protected void installMultiDex() { 
    MultiDex.install(this); 
}

而且在測試應用overrided它：

@Override 
protected void installMultiDex() { 
    //don't do anything 
}

的方式尤金，我想陰影ShadowMultiDex.class是負責這樣做的人。那是對的嗎？我今天也嘗試了你的建議，但仍然在ActiveAndroid.initialize（this）上總是失敗。 – Hilfritz

對'ActiveAndroid'使用類似的技巧。您在逐個測試課程時不需要它 –

嗨Eugen，我不確定你的意思。我需要爲我設置ActiveAndroid來測試數據庫查詢。你能指導我如何在ActiveAndroid上做到這一點。 – Hilfritz
