4. You are a tester in a Scrum team. You have been testing the product for several iterations and you are noticing that the error message format and text are inconsistent. For example, when the user enters an invalid address in one part of the application, they are given the message “Invalid input” in a red font whereas when they enter an invalid phone number they are given the message “The phone number you have entered is not in a valid format. Please enter the phone number as (xxx) xxx-xxxx” in a blue font. The stories do not specify how the error messages should appear. What should you do?
