flymock
Easy to mock external HTTP request in Tornado.
Installation
.. code-block:: shell
$ pip install --upgrade flymock
Create mock data
Make a directory in your tests package:
.. code-block:: shell
$ mkdir __mock__
Use the hostname as the config filename, assume the url is http://example.com/demo
,
the config filename should be example.com.yaml
, the config see below:
.. code-block:: yaml
- path: /demo # path of the request to match
method: GET # method of the request to match
headers: # Response headers
Content-Type: application/json
body: Hello world # Response body
code: 200 # Response status code
- path: /file
body_type: file # Use a file content as the response
body: demo.json # Filename(same path of the config file)
code: 202
- path: /json
body: # If body is an object, that will response JSON content.
code: 2
Usage
.. code-block:: python
import os
from tornado import httpclient
from tornado import testing
from flymock import FlyPatcher
class DemoTestCase(testing.AsyncTestCase):
def setUp(self):
super(DemoTestCase, self).setUp()
path = os.path.join(os.path.dirname(__file__), "__mock__")
self.patcher = FlyPatcher(path)
self.http_client = httpclient.AsyncHTTPClient()
self.patcher.start()
def tearDown(self):
super(DemoTestCase, self).tearDown()
self.patcher.stop()
@testing.gen_test
def test_mocked(self):
resp = yield self.http_client.fetch("http://example.com/demo")
self.assertEqual(resp.code, 200)
Adjust response dynamic:
.. code-block:: python
patcher = FlyPatcher("/path/to/__mock__")
def hook(response):
response.patch_json({"a": 1})
with patcher.dynamic_hook(hook):
# code goes here
pass
# shortcut to adjust JSON
with patcher.patch_json({"a": 1}):
# code goes here
pass
