Reposting this, after discussing with Sean Dague…

For background, I have developed a REST client lib to talk to a H/W device with REST server for VPNaaS in Neutron. To support unit testing of this, I created a UT module and a mock REST server module and used the httmock package. I found it easy to use, and was able to easily create a sub-class of my UT to run the same test cases with real H/W, instead of the mock REST server. See the original email below, for links of the UT and REST mock to see how I used it.


I created a bug under requirements, to propose adding httmock to the test-requirements. Sean mentioned that there is an existing mock package, called httpretty, which I found is used in keystone client UTs), and should petition to see if httmock should replace httpretty, since the two appear to overlap in functionality.

I found this link, with a brief comparison of the two: http://marekbrzoska.wordpress.com/2013/08/28/mocking-http-requests-in-python/

So… I’m wondering if the community is interested in adopting this package (with the goal of deprecating the httpretty package). Otherwise, I will work on reworking the UT code I have to try to use httpretty.

Would be interested in peoples’ thoughts, especially those who have worked with httpretty.

Thanks in advance!

I’d like to get this added to the test-requirements for Neutron. It is a very flexible HTTP mock module that works with the Requests package. It is a decorator that wraps the Request’s send() method and allows easy mocking of responses, etc (w/o using a web server).

The bug is: https://bugs.launchpad.net/neutron/+bug/1282855

Initially I had requested both httmock and newer requests, but was requested to separate them, so this is to target httmock as it is more important (to me :) to get approval,


The review request is: https://review.openstack.org/#/c/75296/

An example of code that would use this:

https://github.com/openstack/neutron/blob/master/neutron/tests/unit/services/vpn/device_drivers/notest_cisco_csr_rest.py
https://github.com/openstack/neutron/blob/master/neutron/tests/unit/services/vpn/device_drivers/cisco_csr_mock.py

Looking forward to hearing whether or not we can include this package into Juno.

Thanks in advance!
