How do you automatically detect if your signup/login is down?

Question

My SaaS product&rsquo;s auth was broken for 3 days and I only noticed today. I&rsquo;d like to set up an automated way to test signup and login flows continuously, and alert me if something fails.What&rsquo;s the simplest and most reliable way to do this? Tools, scripts, or best practices welcome.

Was the auth page straight up down? So http down? If so, something like PRTG can tell you when that's down.
If it's a page up, but backend down in some way. Now that's a big question of what the code is doing.
If perhaps auth is easy as a post request with creds and it returns with a success of some kind. Could be trivial to setup using python requests.
