Robolectric 单元测试因 Android Studio 2.3 更新而失败
Robolectric Unit Test failing with Android Studio 2.3 updates
我所有的单元测试都开始抛出这个错误：

它工作得很好。我唯一改变的是我将 Android Studio 更新为 2.3，并将 gradle 插件更新为 2.3。到目前为止，我通过在每个测试的 运行 配置路径中手动记下 $MODULE_DIR$ 来修复它。但是每次都写下来真的很烦人。有没有人经历过这样的事情？
默认设置它，因此您创建的每个新测试配置都将继承它：
运行 > 编辑配置... > 默认值 > Android JUnit
在工作目录中输入：$MODULE_DIR$
Android 工作室正在查看 APP 文件夹以从 AS 2.3 版本进行 运行 测试。如果您有自定义 Roboelectric Runner 扩展 RoboelectricTestRunner，您可以覆盖其中的工作目录，而不是每次都从编辑配置中设置 WORKING DIR。
这是我的代码。
public class CustomRobolectricRunner extends RobolectricTestRunner {
// Build output location for Android Studio 2.2 and older
private static final String BUILD_OUTPUT = "build/intermediates";
// Build output location for Android Studio 2.3 and newer
private static final String BUILD_OUTPUT_APP_LEVEL = "app/build/intermediates";
public CustomRobolectricRunner(Class<?> testClass) throws InitializationError {
super(testClass);
}
@Override
protected AndroidManifest getAppManifest(Config config) {
FileFsFile res = FileFsFile.from(BUILD_OUTPUT, "/res/merged", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE);
FileFsFile assets = FileFsFile.from(BUILD_OUTPUT, "assets", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE);
FileFsFile manifest = FileFsFile.from(BUILD_OUTPUT, "manifests", "full", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE, "AndroidManifest.xml");
// If above files does not exist in the specified paths, look them at the app folder level. This is needed
// as Android studio 2.3 changed the working directory.
if (!manifest.exists()) {
manifest = FileFsFile.from(BUILD_OUTPUT_APP_LEVEL, "manifests", "full", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE, "AndroidManifest.xml");
}
if (!res.exists()) {
res = FileFsFile.from(BUILD_OUTPUT_APP_LEVEL, "/res/merged", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE);
}
if (!assets.exists()) {
assets = FileFsFile.from(BUILD_OUTPUT_APP_LEVEL, "assets", BuildConfig.FLAVOR, BuildConfig.BUILD_TYPE);
}
AndroidManifest androidManifest = new AndroidManifest(manifest, res, assets) {
@Override
public Class getRClass() {
return R.class;
}
public int getTargetSdkVersion() {
/**
* Lollipop is currently the highest version supported in 3.0.
*/
return Build.VERSION_CODES.LOLLIPOP;
}
};
return androidManifest;
}
当有人遇到这个问题时，对于这种情况，添加这一行应该会有所帮助
