I am using robolectric in our unit tests. Recently in our project, we are adding a new dependency from zendesk.
repositories {
maven {
url 'https://zendesk.artifactoryonline.com/zendesk/repo'
}
}
compile group: 'com.zendesk', name: 'sdk', version: '1.3.0.1'
Now we have not even referenced any class from this library and we are getting exceptions in our robolectric unit tests just by adding this dependency. I thought the problem is in our project, but its also occurring on a sample robolectric test project.

Found the fix for this. We were not using zendesk code in our test cases. The broadcast receivers from the added dependency(zendesk) were getting added to AndroidManifest.xml through the gradle build. The RobolectricTestRunner class parses the manifest into its internal ApplicationManifest object and then sets up application state through ShadowApplication class. The ShadowApplication class registers broadcast receivers from the application manifest. This is where I was getting the above error.
Fix: We have a custom test runner that extends RobolectricGradleTestRunner. In that I have overriden the getAppManifest method and removed the broadcast receivers not required. I know its a kind of workaround but there was no other alternative. Didn't want to create another manifest and create duplication. Here's the code snippet.
@Override
protected AndroidManifest getAppManifest(org.robolectric.annotation.Config config) {
AndroidManifest manifest = super.getAppManifest(config);
List<BroadcastReceiverData> broadcastReceivers = manifest.getBroadcastReceivers();
List<BroadcastReceiverData> removeList = new ArrayList<>();
for(BroadcastReceiverData receiverData : broadcastReceivers) {
if(isDeletePackage(receiverData.getClassName())) {
removeList.add(receiverData);
}
}
broadcastReceivers.removeAll(removeList);
return manifest;
}
private boolean isDeletePackage(String className) {
for(String s : DELETE_BROADCAST_PACKAGE) {
if(className.startsWith(s)) {
return true;
}
}
return false;
}
The DELETE_BROADCAST_PACKAGE is simply a String hashset. Containing the package hierarchy name
