To make sure that the web site doesn't break, we should have integration tests which check that the generates pages for the web site meet our expectations.

They should cover things like:

• Generation of proper HTML
• Checks for navigation
• Checks for display of library details
• Make sure that data consumed by programs is correct, such as the JSON for all libraries.
• Check that the search is generated correctly and works
• Check that the comments are generated correctly and work
