Problem: There is a lot of redundancy in the code around the XML and 
JSON API formats and API versions. The client classes are very low-level 
and hard to use.

There should be a single general class for each service that would 
contain as much common code as possible. Then there would be derived 
classes for JSON, XML and different API versions that would only 
overwrite the differences. Ideally, there could be derived class that 
would also handle the CLI.
How to do this with the least amount of redundancy?

This way, the tests would be written only once and most of them run for 
each API version/format. Then there would be tests for only a specific 
API version, when new API features would be tested.

The general classes should also be more high-level. They could 
themselves manage the resources that were created with them and be able 
to clean them up. The classes would check the response codes themselves 
and throw exceptions, instead of having
"assertEqual(resp['status'], '200')"
everywhere in the test code.


Thoughts?
