It would be helpful if someone with experience around ux unit tests can help us get some basic testing set up for starters. We are not attached to any one technology - so open to suggestions on the best ways to do this. Ideally we have some basic UX testing in place that we can run before release to make sure we are not breaking at least some basic user flows. For example opening a forecast and making sure sections load with data we expect. Or opening an observation and making sure it loads with data we expect.

Today when we have major changes we do all the ux testing manually in the preview app following a doc that specifically has us follow our most common user flows and we look for any issues we spot during that run through. This is working okay but can be time consuming.
