Python Test - Lambda Mock fails

[boenhoff]

I'm trying to get started with python lambda tests, especially mock tests.

I cloned the whole repository and then executed make install and make test in python-test-samples/lambda-mock but 3 of 4 failed. Does that work for somebody else?

Test Repo I'm testing: https://github.com/aws-samples/serverless-test-samples/tree/main/python-test-samples/lambda-mock
