Users change their minds. They save new items in your app, then want to delete those saved items and try again. Does your AUT support this behavior? Did you test for it?
My devs recently added a dropdown control with two values (i.e., DVS or ESP). Soon after being able to save or change the values, I stopped testing. Later, a user pointed out there is no way to remove the values from that (optional) field if you change your mind. Now, many of our dropdowns look like this:
While testing, I often look for data saving triggers (e.g., a button that says “Save”). Then I ask myself, "Okay, I saved it by mistake, now what?".
