Robolectric 3.3.2 Facebook 4.3 and above compatability issues - facebook-android-sdk

Question

I have issues running my unit tests with a specific version of Robolectric and Facebook. My test scripts work when I have the following
testCompile "org.robolectric:robolectric:3.3.2"
testCompile "org.robolectric:shadows-multidex:3.3.2"
testCompile 'org.robolectric:shadows-support-v4:3.3.2'
and
compile 'com.facebook.android:facebook-android-sdk:4.2.0'
But, when I upgrade to
compile 'com.facebook.android:facebook-android-sdk:4.22.0'
I get the following issues:
WARNING: unknown service appops
WARNING: no system properties value for persist.radio.multisim.config
The Facebook sdk must be initialized before calling activateApp

Any idea how to fix the issue?

Since 4.19, Facebook SDK does an automatic init process. Robolectric doesn't start it properly, hence the crash.
If you don't need Facebook SDK initialized, a perfectly valid solution is shadowing activateApp call. Create this class:
#Implements(AppEventsLogger.class)
public class ShadowAppEventsLogger {
#Implementation
public static void activateApp(Application application) {
// Do nothing, just shadow
}
}
and attach it to your test:
#Config(shadows = {ShadowAppEventsLogger.class, ...}, ... )
#Test public void fooTest() {...}
