Testing platform needed

[jvasile]

We need to automatically test the major functions: planet creation, add/remove feed, edit planet metadata, update planets, generate atom/html/opml files. Maybe twill can help.

[jvasile]

There are some nose tests in the test directory, which is a start, but not a great one.

And now some twill tests are in place. See new_planet_test.py for those. This is progressing, but we need way more test coverage.

Twill doesn't do javascript, which means we'll need selenium for at least some things (like the admin interface).

Note that code coverage metrics are b0rked when nose hits a a CGI via local apache instance. And there are issues with running selenium related to user www-data not having access to the running x server. Lots to iron out here...
