Hi guys. It looks like "file.spec.144 copyTo: asset directory" tries to copy whole www directory. Was it done intentionally? On slow environments, especially emulators this can take huge amount of time (up to 5 minutes).
In case it is not substantial and any folder will do, I've prepared a fix for this test to stop timing out on Android emulators: https://github.com/apache/cordova-plugin-file/pull/129 Thanks, Alexander Sorokin
