Switched out sqlite3 libs in favour of SQLAlchemy v0.9, will gradually migrate dialects and scheme to be fully SQLAlchemy compliant for using there ORM with sessions instead of direct. Fixed getEpisode function to stop making unrequired scene number conversions on already converted data thats available now from cache.

"""Extensions to unittest for web frameworks.
|
|
|
|
Use the WebCase.getPage method to request a page from your HTTP server.
|
|
|
|
Framework Integration
|
|
=====================
|
|
|
|
If you have control over your server process, you can handle errors
|
|
in the server-side of the HTTP conversation a bit better. You must run
|
|
both the client (your WebCase tests) and the server in the same process
|
|
(but in separate threads, obviously).
|
|
|
|
When an error occurs in the framework, call server_error. It will print
|
|
the traceback to stdout, and keep any assertions you have from running
|
|
(the assumption is that, if the server errors, the page output will not
|
|
be of further significance to your tests).
