This is nice to know. Do Quicklisp packages typically come with test suites? At least then I can check if a package will work before I commit to using it.

But unfortunately not all libraries set up their test-ops properly. You can usually find a readme at ~/quicklisp/dists/quicklisp/software/... which might have instructions for running tests.
