The incoming parameters of assertEqual function are reversed

[xiangxinyong]

The incoming parameters of assertEqual function are reversed in MuranoClient.

For example.

self.assertEqual(self.client.packages.create.call_count, 2)

According the definition of assertEqual as below, it is reversed.

def assertEqual(self, expected, observed, message=''):
        :param expected: The expected value.
        :param observed: The observed value.
        :param message: An optional message to include in the error.

It may create misunderstanding about unit test.
