Python unittest's assertDictContainsSubset recommended alternative

Question

Answer 1

If you were testing if dict A is a subset of dict B, I think I would write a function that tries to extract the content of dict A from dict B making a new dict C and then assertEqual(A,C).

def extractDictAFromB(A,B):
    return dict([(k,B[k]) for k in A.keys() if k in B.keys()])

then you could just do

assertEqual(A,extractDictAFromB(A,B))
