[Idea validation]: Do you test your SaaS?

I know, startups are all about the speed and forgiveness of the first customers, who were able to extract the right value from your product, but anyway. Would you be interested in service providing you a set of standard automated checks (with monitoring/scheduled runs/etc) of the features, you've chosen? Lots of parts of SaaS are common, so my idea is to extract the most useful and use these tests as a scaffold or even milestones (in the test-first paradigm). Like you

1. enter a URL
2. choose needed checks
3. enter environment variables(if needed)
   ==> you got the page with the test results, which updates on schedule(or webhooks) and link to your generated test repo.
   No need for prepared ci(like small starter-kit)(not a replacement for ci or qa-on-demand)

Would you use that service?
