For follow/unfollow: Script could be:

• Have 3 dummy users A B and C.
• Initially have A follow B. C has no relation with either.
• Check if A is following B -> should be true.
• Check if C is follow B -> should be false
• Make C follow A. Then check if A is being followed by C -> should be true
• Make C unfollow A. Then check if C follows A. -> should be false
• IMPORTANT: no matter how the script goes, the last operations should come back to initial state: A follows B and C has no relation.
