Yes. Since, by definition, these projects aren't worked on full-time you need to know that any changes you do find time to apply are not going to kill your site/service. I don't have 100% coverage, but I do have a lot of test-cases which cover areas that are "hard". Or in response to customer bug-reports to ensure I don't have any surprises. (My service has a fair number of moving-parts, using a job-queue, service workers, a web-site, and integration with an external DNS provider, or two.)
