If the API you’re mocking already exists you can speed up the process of stubbing responses using MockLab’s record feature. This essentially involves telling MockLab to act as a proxy to the target API then directing some HTTP requests to MockLab representing the resources you’d like to stub.
A simple recording example
Once you have logged into MockLab and created a mock API, navigate to the Stubs page.
Then hit the button,
http://ip-api.com as the target URL and hit .
Now make a request to your mock API (substituting
my-mock-api for your own sub domain name):
$ curl -v http://my-mock-api.mocklab.io/json
This request will be proxied through MockLab, so that a
GET request will be made to
http://ip-api.com/json and the result captured.
Now hit , and you should see that an extra stub has been added to the list.
Request matching rules when recording
When a request with no body is received during recording, the recorder will create a stub matched on HTTP method and URL only.
When a request with a body is received a body pattern is also included. If the request body is a valid JSON document,
equalToJson operator will be used. If XML, the
equalToXml operator will be used. Otherwise the operator will be
equalTo i.e. simple string equality.
