This method may be called only once per test-case to avoid odd

and difficult to debug interactions. Discovery and Auth request mocking
|
|
happens separately from this method.
|

:param uri_mock_list: List of dictionaries that template out what is
|
|
passed to requests_mock fixture's `register_uri`.

Format is:
|
|
{'method': <HTTP_METHOD>,
|
|
'uri': <URI to be mocked>,
|
|
...
|
|
}
|
|
|
|
Common keys to pass in the dictionary:
|
|
* json: the json response (dict)
|
|
* status_code: the HTTP status (int)
|
|
* validate: The request body (dict) to
|
|
validate with assert_calls
|
|
all key-word arguments that are valid to send to
|
|
requests_mock are supported.
|
|
|
|
This list should be in the order in which calls
|
|
are made. When `assert_calls` is executed, order
|
|
here will be validated. Duplicate URIs and
|
|
Methods are allowed and will be collapsed into a
|
|
single matcher. Each response will be returned
|
|
in order as the URI+Method is hit.
