Topic: Is it necessary to test plugins?

Since most plugins have there own suite of test with them, is it really necessary to test them? Especially if you're using it in more than one place or its system wide. I mean with something like acts_as_taggable_on_steriods or will_paginate. I just wanted to know what the general thought on this was.

Re: Is it necessary to test plugins?

If the plugin already has a test suite, then there's no point in duplicating the work. However, there are sometimes edge cases on how your application interacts with the plugin, so it's a good idea to get a higher-level test where your application is using the plugin. You generally don't have to worry about this if your app has a good test suite.
