We are in a very funny situation where I just spent two weeks fixing FE bugs and there are so many left. I asked to add integration tests but the answer was “no”, cause we can’t test the UI and all of that.
So the proposed solution was to be more careful, except I’m careful but testing whole website parts or the whole website is not feasible. What can I do?
Just do it, whenever you fix a bug, add a test case for it, the cost is not going to be noticeable. You may choose to not upload the test suite right away, but wait until someone notices and asks you about it.
