I am working on a project that has an application that has several different specific error messages that are raised during certain scenarios with specific data. I have been tasked to come up with a Test Case/Plan which can be given to testers to test this.
e.g. user loses internet connection and error code x is displayed user account is locked and error code y is displayed
Can anyone recommend a template that can be used to do this? I have very little QA experience.
