Creating an Adapter
===================
The standard `requests`_ means of using an adapter is to :py:meth:`requests.Session.mount` it on a created session. This is not the only way to load the adapter, however the same interactions will be used.

Whilst it is preferable to provide the whole URI to :py:meth:`requests_mock.Adapter.register_uri` it is possible to just specify components.
The examples in this file are loaded with:
.. doctest::
>>> import requests
>>> import requests_mock
>>> adapter = requests_mock.Adapter()

>>> session.mount('mock', adapter)
Basic
=====
.. doctest::
:hide:
>>> import requests
>>> import requests_mock
>>> adapter = requests_mock.Adapter()
>>> session = requests.Session()
>>> session.mount('mock', adapter)
You can specify a protocol-less path:
.. code:: python
.. doctest::
>>> adapter.register_uri('GET', '//test.com/5', text='resp')
>>> session.get('mock://test.com/5').text
'resp'
.. >>> adapter.register_uri('GET', '//test.com/', text='resp')
.. >>> session.get('mock://test.com/').text
.. 'resp'
or you can specify just a path:
.. code:: python
>>> adapter.register_uri('GET', '/6', text='resp')
>>> session.get('mock://test.com/6').text
'resp'
>>> session.get('mock://another.com/6').text
'resp'
