At first I explored cucumber and saw that it was ruby based. So I
veered off to find pyparsing and how to implment custom DSLs and it
looked like a lot of work. Ruby lends itself well to implementing
custom DSLs it seems [1]. Lettuce, I see now, does this with python
and it doesn't look too hard to get it working for basic scenarios. [2]
The trouble seems to be creating cloudstack entities that often take a
lot of params to just be created. Eg: networkoffering. For this I
think factories of default objects that we see on the UI can help. So
we have
NetworkOfferingFactory
DefaultWithIsolatedSourceNAT
DefaultForSharedNetwork
etc
that will give us default objects that we can pass to marvin's
integration library to interact with the api server and have them
mapped via lettuce. if additional params are required one can
implement a factory and get going. I started working on such factories
in the marvin-refactor-phase1 branch but am open to any other ideas to
implement a dsl with minimal typing.
