A question about your testing if you have time. Is this done in a fake
WSGI hosting environment, ie., test harness, or is it able to be run
through WSGI servers such as Paste server, Apache/mod_wsgi, etc, in
some way?
The tests I mentioned in there are mostly unit tests; they don't test any
particular system configuration functionally. In particular, none of the tests
actually invokes a request via a WSGI stack.
But we do use functional testing in projects that use the framework. For
example, we use Twill (created by Titus Brown) to make sure things don't break
at the request/response level in this project: http://karlproject.org.
Am curious from the point of view that standalone test suites for WSGI
itself to run against WSGI hosting mechanisms don't really exist, so
the test suite for BFG, with the presumption that it would exercise a
lot of WSGI functionality, might be a good regression test for WSGI
servers themselves.
I think maybe some "ACID test" WSGI application could be built, and then some
set of functional HTTP-level tests could be run against that application to gain
confidence in a WSGI app. This is more or less what we do with Twill on that
KARL project: the developers use the Paste#http server, but we actually deploy
to a mod_wsgi server. We can (and do) run the Twill tests against both to get
confidence that the app isn't going to fall over in production.
