 The unit tests are stored in the `test/awx` directory and, where possible, test interactions between the collections modules and the AWX database. This is achieved by  using a Python testing suite and having a mocked layer which emulates interactions with the API. You do not need a server to run these unit tests. The depth of testing is not fixed and can change from module to module.

-    assert len(tokens) == 1, 'Tokens with description of barfoo != 0: {0}'.format(len(tokens))

-This test has a single test called `test_create_token`. It creates a `module_args` section which is what will be passed into our module. We then call `run_module`, asking it to run the `token` module with the `module_args` we created and give us back the results. After that, we run an assertion to validate that our module did in fact report a change to the system. We will then use Python objects to look up the token that has a description of `barfoo` (which was in our arguments to the module). We want to validate that we only got back one token (the one we created) and that the scope of the token we created was read.
