Mock out responses from the requests package
Everything in requests eventually goes through an adapter to do the transport work. requests-mock creates a custom adapter that allows you to predefine responses when certain URIs are called.
There are then a number of methods provided to get the adapter used.
A simple example:
>>> import requests >>> import requests_mock >>> session = requests.Session() >>> adapter = requests_mock.Adapter() >>> session.mount('mock://', adapter) >>> adapter.register_uri('GET', 'mock://test.com', text='data') >>> resp = session.get('mock://test.com') >>> resp.status_code, resp.text (200, 'data')
Obviously having all URLs be mock:// prefixed isn’t going to be useful, so you can use requests_mock.Mocker to get the adapter into place.
As a context manager:
>>> with requests_mock.Mocker() as m: ... m.get('http://test.com', text='data') ... requests.get('http://test.com').text ... 'data'
Or as a decorator:
>>> @requests_mock.Mocker() ... def test_func(m): ... m.get('http://test.com', text='data') ... return requests.get('http://test.com').text ... >>> test_func() 'data'
Or as a pytest fixture:
>>> def test_simple(requests_mock): ... requests_mock.get('http://test.com', text='data') ... assert 'data' == requests.get('http://test.com').text
