Review comment:
Note that there is a difference between `()` and `return_value`.
With `()` you are actually calling the mock. With `return_value` you don't.
However you won't notice if you don't test for the number of mock calls of
this particular mock object. For example `.get_conn`.
I recommend to use `return_value` to not extra call the mock object.
