GHOP task #128: Create tests for book

The GHOP task associated with this issue can be found at:
http://code.google.com/p/google-highly-open-participation-drupal/issues/...

After allot of messing around to decide what worked and what didn't and what was the best way to do it I finally came up with the attached solution. I believe it meets all the requirements posted on GHOP.

Made a few changes, due to requests made on IRC:

• Fixed name of class
• Removed unnecessary permissions
• Created two users: one to create book content, and one to view

Tests look good and test everything we asked for. I made two changes to your file

• Added setup function which is not needed but it is usually there for stuff like enabling modules or if you have few test functions that use same user perm you can put user creation in there
• log out at the end is not needed, simpletest creates new browser session for every test function>

Before I mark this RTBC I'd like to see some documentation for your helper functions checkBookNode, generateOutlinePattern and createBookNode. Brief description of what function does, params and what does it return.

I believe I have made all the requested changes.

Thanks committed.
