I have a tricky question and I'm not sure if calling it "unit testing" is the right thing to do as I am by no means a UX person - I am learning a lot though.
I have a website and I'm trying to perform unit testing on the user experience, if that's possible.
For example, everytime the backend is updated, I want to ensure that the user experience doesn't change in order to make sure the system is running smoothly. In this way, it is a unit-testing framework but not at the source code level.
What kind of frameworks can help with this?
