A utility library for mocking out the requests Python library.
import responses
import requests
@responses.activate
def test_my_api():
responses.add(responses.GET, 'http://twitter.com/api/1/foobar',
body='{"error": "not found"}', status=404,
content_type='application/json')
resp = requests.get('http://twitter.com/api/1/foobar')
assert resp.json() == {"error": "not found"}
assert len(responses.calls) == 1
assert responses.calls[0].request.url == 'http://twitter.com/api/1/foobar'
assert responses.calls[0].response.text == '{"error": "not found"}'import json
import responses
import requests
@responses.activate
def test_calc_api():
def request_callback(request):
payload = json.loads(request.body)
resp_body = {'value': sum(payload['numbers'])}
headers = {'request-id': '728d329e-0e86-11e4-a748-0c84dc037c13'}
return (200, headers, json.dumps(resp_body))
responses.add_callback(
responses.GET, 'http://calc.com/sum',
callback=request_callback,
content_type='application/json',
)
resp = requests.post(
'http://calc.com/sum',
json.dumps({'numbers': [1, 2, 3]}),
headers={'content-type': 'application/json'},
)
assert resp.json() == {'value': 6}
assert len(responses.calls) == 1
assert responses.calls[0].request.url == 'http://calc.com/sum'
assert responses.calls[0].response.text == '{"value": 6}'
assert (
responses.calls[0].response.headers['request-id'] ==
'728d329e-0e86-11e4-a748-0c84dc037c13'
)Instead of passing a string URL into responses.add or responses.add_callback you can also supply a compiled regular expression.
import re
import responses
import requests
# Instead of
responses.add(responses.GET, 'http://twitter.com/api/1/foobar',
body='{"error": "not found"}', status=404,
content_type='application/json')
# You can do the following
url_re = re.compile(r'https?://twitter.com/api/\d+/foobar')
responses.add(responses.GET, url_re,
body='{"error": "not found"}', status=404,
content_type='application/json')Note
Responses requires Requests >= 1.0
