Client for the pretenders mock server
The pretenders project creates flexible fakes for external network services. These external services can be faked by setting pre-canned answers, defining expectations, or just querying them on received data after [test] execution.
They are loosely designed along the pattern of Record/Replay/Verify.
The server side of Pretenders is written in Python3:
In the cases we implement a client, we will be making this runnable in Python 3.x and Python 2.6/2.7.
Pretenders currently supports the mocking of HTTP and SMTP servers.
Future services we are considering to support include AMQP and ssh.
These represent the vast majority of the services that the software we write interacts with.
Some example use cases include:
Pretenders provides a unified RESTful API to verify the interactions of our code with external services, regardless of the service protocol.
Typical usage is to mock RESTful/SOAP APIs of external services.
This will normally require pre-programming the service with responses, and enquiring the service later about received requests. This can be done with specialised assertions / matchers, or by setting expectations and verifying fulfilment of such expectations.
The pre-programming step may be done by using specific proprietary HTTP headers, or by using an alternative HTTP port to the one used for mocking.
For example usage see the documentation.
Implementation is based on the bottle web microframework.
One of our goals will be that the wire protocol is simple enough that you do not need any specialised client. That said, we will be providing client libraries (at least one in Python) to simplify interacting with the server, and to provide a comfortable API to use in tests.
For discussions about the usage, development, and future of pretenders, please join the pretenders mailing list.

We have the following branching convention:
- master: This should look exactly like the latest release.
- develop: This is where ongoing work lands, only being merged into master at release point.
In order to contribute, fork the repo in github and branch from the develop branch. Create your PRs into develop in the main repo.
build.sh runs the full suite of tests, as well as building the sphinx docs and checking for pep8 errors.
