Our client is in the process of doing regression testing on an app for which we did the UX part. Obviously, we took the previous version in consideration, so we have a lot of insight about it and I think we could help with this since usability changes were quite a few (previous one was a mess).
However, the client says that the entire process of regression testing belongs to development area, including usability, which sounds really weird to me since most of the testing will be performed with automated tools and the manual parts mostly fall under our domain
In general, I'd agree with the client, but based on my experience with those developers (which, by the way, designed the UX for the previous version) and the fact that there are many changes, I think we should at least overview the regression testing.
Am I wrong about this? Should regression testing include UX or not? And as we're at it, what's the name for regression testing in UX?
