Add unit tests for chef state
Add unit tests for chef state

These tests cover the entire state, but are only concerned with the
ret["result"] of the outputs. It would be a good idea to test other
outputs as well - these tests could be modified to include assertions
about the other parts of ret. (Obviously they would need to be slightly
renamed. Maybe to `..._return_expected_ret`
