API Unit / integration / feature tests

[sy238-unikent]

Need to setup a good framework for testing the API, including fixture data, etc.

As part of that, lets fix all the not currently implemented test stubs.

Short term I think testing making requests at the API level would be a good start:

Fixtures:

• 4 users, 1 of them an admin.
• 1 site, with the non-admin users as an owner, editor and contributor.
• 2 test site definitions
• 2 test layout definitions
• Entirely unpublished pages:
• Homepage
  • Page 1
    • Subpage 1.1
    • Subpage 1.2
  • Page 2
    • Subpage 2.1
    • Subpage 2.2
• Data providers to provide both valid and invalid json request data, together with expected response status codes and json data.

Starting with tests around the createsite api endpoint.
