How to automate post update website check?

I don’t know what big agencies do, but I can tell you one developer tool that can be used to automate this kind of testing: Codeception.

What this sort of testing is technically called is acceptance testing. Codeception allows you to write automated acceptance tests. It even has an extension that will take screenshots and automatically compare them for you.

Of course, Codeception tests can actually go further than just taking screenshots, they can actually fill out and submit forms, click buttons and links on the site, etc. (Of course, you probably won’t want to test most forms on a live site, depending on what they do. 🙂

Using Codeception may require you to write some code, but most of your tests will probably be very simple and will take minimal work to get going.
