Request History

The object returned from creating a mock or registering a URI in an adapter is capable of tracking and querying the history of requests that this mock responded to.

Called

The easiest way to test if a request hit the adapter is to simply check the called property or the call_count property.

>>> import requests
>>> import requests_mock

>>> with requests_mock.mock() as m:
...     m.get('http://test.com', text='resp')
...     resp = requests.get('http://test.com')
...
>>> m.called
True
>>> m.call_count
1

Request Objects

The history of objects that passed through the mocker/adapter can also be retrieved.

>>> history = m.request_history
>>> len(history)
1
>>> history[0].method
'GET'
>>> history[0].url
'http://test.com/'

The alias last_request is also available for the last request to go through the mocker.

This request object is a wrapper around a standard requests.Request object with some additional information that make the interface more workable (as users do not generally deal with the Request object).

These additions include:

text:The data of the request converted into a unicode string.
json:The data of the request loaded from json into python objects.
qs:The query string of the request. See urllib.parse.parse_qs() for information on the return format.
hostname:The host name that the request was sent to.
port:The port the request was sent to.
>>> m.last_request.scheme
'http'
>>> m.last_request.hostname
'test.com'

The following parameters of the requests.request() call are also exposed via the request object:

timeout:How long to wait for the server to send data before giving up.
allow_redirects:
 Set to True if POST/PUT/DELETE redirect following is allowed.
proxies:Dictionary mapping protocol to the URL of the proxy.
verify:Whether the SSL certificate will be verified.
cert:The client certificate or cert/key tuple for this request.

Note: That the default values of these attributes are the values that are passed to the adapter and not what is passed to the request method. This means that the default for allow_redirects is None (even though that is interpretted as True) if unset, whereas the default for verify is True, and the default for proxies is the empty dict.

Reset History

For mocks, adapters, and matchers, the history can be reset. This can be useful when testing complex code with multiple requests.

For mocks, use the reset_mock() method.

>>> m.called
True
>>> m.reset_mock()
>>> m.called
False
>>> m.call_count
0

For adapters and matchers, there is a reset() method. Resetting the adapter also resets the associated matchers.

>>> adapter = requests_mock.adapter.Adapter()
>>> matcher = adapter.register_uri('GET', 'mock://test.com', text='resp')
>>> session = requests.Session()
>>> session.mount('mock://', adapter)
>>> session.get('mock://test.com')
>>> adapter.called
True
>>> adapter.reset()
>>> adapter.called
False
>>> matcher.called  # Reset adapter also resets associated matchers
False

However, resetting the matcher does not reset the adapter.

>>> session.get('mock://test.com')
>>> matcher.called
True
>>> matcher.reset()
>>> matcher.called
False
>>> adapter.called  # Reset matcher does not reset adapter
True
