    `dict['attribute']` notation. It also has all of dict's methods.

I started out pasting Python code into the AWS Lambda web GUI, right in that textarea. Got it working, making a call to a Slack API (whee!). So I had a working test case and I could test a refactor.

With the same code, I wanted to take advantage of the cool zipfile/ virtualenv upload support ("Create a Deployment Package") so I could use third-party libraries. Keeping the code itself the same (same as what I'd pasted into the textarea), the test should work again, as long as I packaged it right.

I kept trying to upload a zip with the same code, I thought, to AWS Lambda ... but I kept getting an error:

# A coworker of mine covinced himself that the built-in pytest doctest support module didn't integrate with pytest-cov.
# He wrote his shim to get around this. Not necessary though.
# The gist is to make sure you have "--doctest-modules" and "--cov-report" and "--cov" arguments.

py.test . --doctest-modules --cov-report term --cov=.
# or
py.test mymodule --doctest-modules --cov-report term --cov=mymodule
