"""
We are using unittest for troggle.

Note that the database has not been parsed from the source files when these tests are run,
so any path that relies on data being in the database will fail.

The simple redirections to files which exist, e.g. in
/expoweb/
/expofiles/
/expofiles/documents/
etc. will test fine.

But paths like this:
/survey_scans/
/caves/
which rely on database resolution will fail unless a fixture has been set up for
them.
