pretenders 0.0.1

Fake servers for testing

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.

Pretenders will be written in Python3:

• Because it is about time

• Because since these will be standalone servers, compatibility is not such an issue

Initial goal for services to be mocked by pretenders: HTTP, SMTP

pretenders.http - HTTP server

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 queries. 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.

Implementation is based on http.server.HTTPServer

A client library will be provided to simplify interacting with the server.

pretenders.smtp - SMTP server

Typical usage is to record a system’s outgoing mail for further analysis. No pre-programmed responses are necessary, just an API for checking status and retrieving sent messages.

Implementation is based on smtpd.SMTPServer
