Authentication and Testing

[calebsyring]

A lambda function runs as a role. Typically, you'd configure that role so whatever permissions etc you need in AWS using it's APIs and/or Terraform (mu does this for some things already). So you don't pass AWS credentials to the lambda.

For unit testing, moto mocks AWS and generally assumes you have permissions to everything. So unit tests are really more about checking the logic of the function.

We'll need to utilize integration tests (mu helps with that) and tweak authentication accordingly.
