Testing

All tests have the following structure:

def test_foo(self):
    data = {...}
    expected_valid = True # or False
    expected = {...} # or omitted

    # setup (without serializer)
    ...

    # testing
    serializer = MyParentSerializer(data=data, ...)
    # validate data
    assert serializer.is_valid() == expected_valid, serializer.errors
    # derserialization
    instance = serializer.save()
    # serialization
    result = MyParentSerializer(instance=instance).data
    # validate result
    assert result == expected, f"\nResult:   {result}\nExpected: {expected}"
