I wrote a set or perl tests scripts using the LWP modules, HTML::Form,
HTML::LinkExtractor, HTML::Lint that are used to test codestriker out.
It is pretty easy to test a web base application with perl. You write a
proxy .pm for each page in bugzilla. The proxy uses LWP, and friends to
manipulate the actual service. Your .t files then use the proxies to do
the tests. We used to have a smoke test document. The smoke test is all
automated now + a bunch of other tests that we were not doing before.
Compared to the complexity of bugzilla, these tests would really not be
that big of a deal to write. It is really easy to at least make sure all
of the links are good, and the generated html is well formed.
The code is here.
Once the infrastructure is in place, then you can insist that every new
features get checked in with test cases. I know that there are plans to
test the pm files inside of bugzilla directly, but you really can't
escape the fact that it needs to work property at the
http/html level. I don't think doing both is unreasonable.
Not everything will be easy to automate, so a test document is also a
