無法使用Gradle和Android Studio運行Robolectric測試 - 找不到StyleData

Question

我下載了deckard-gradle項目，並且我創建了自己的這個寺廟。

我的問題是Robolectric.2.3不想運行測試類。

這是我的錯誤：

java.lang.RuntimeException: huh? can't find parent for StyleData{name='AppTheme', parent='Theme_AppCompat_Light_DarkActionBar'}

我遇到類似的問題，RobolectricTestRunner找不到的Android庫的依賴。爲了解決這個問題，你需要擴展RobolectricTestRunner來把它們拉入.android-maven-plugin根據插件的版本將你的APK依賴項解壓到「target/unpack/apklibs」或者「target/unpacked-libs」。我粘貼下面的例子解決了第二個問題。

public class MyTestRunner extends RobolectricTestRunner { 

    public MyTestRunner(Class<?> testClass) throws InitializationError { 
     super(testClass); 
    } 

    @Override 
    protected AndroidManifest createAppManifest(FsFile manifestFile, FsFile resDir, FsFile assetsDir) { 
     return new MavenAndroidManifest(manifestFile, resDir, assetsDir); 
    } 

    public static class MavenAndroidManifest extends AndroidManifest { 
     public MavenAndroidManifest(FsFile androidManifestFile, FsFile resDirectory, FsFile assetsDirectory) { 
      super(androidManifestFile, resDirectory, assetsDirectory); 
     } 

     public MavenAndroidManifest(FsFile libraryBaseDir) { 
      super(libraryBaseDir); 
     } 

     @Override 
     protected List<FsFile> findLibraries() { 
      // Change "target/unpacked-libs" to "target/unpack/apklibs" 
      //if youe have older version of android-maven-plugin 
      FsFile unpack = getBaseDir().join("target/unpacked-libs"); 
      if (unpack.exists()) { 
       FsFile[] libs = unpack.listFiles(); 
       if (libs != null) { 
        return Arrays.asList(libs); 
       } 
      } 
      return Collections.emptyList(); 
     } 

     @Override 
     protected AndroidManifest createLibraryAndroidManifest(FsFile libraryBaseDir) { 
      return new MavenAndroidManifest(libraryBaseDir); 
     } 
    } 
} 

後來在測試用例使用這樣的：

@RunWith(MyTestRunner.class) 
@Config(emulateSdk = 18) 
public class MyActivityTest{ 
}
