It worked just fine. The only thing that I changed is that I updated Android Studio to 2.3 and the gradle plugin to 2.3. So far I fix it by manually writing down $MODULE_DIR$ in each test's Run Configuration path. But is really annoying write it down every time. Has anyone experience something like this?
回答1:
Set it by default, so every new test configuration that you create will inherit it:
Run > Edit Configurations... > Defaults > Android JUnit
in Working directory enter: $MODULE_DIR$
回答2:
Android studio is looking at APP folder to run tests from AS 2.3 version. If you have Custom Roboelectric Runner extending RoboelectricTestRunner, you can override the working directory inside that, instead of setting WORKING DIR from edit configurations every time.
Here is my code.
`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;
}`
