How should I create a test case, or what should the test case be, when the scenario is for a function that shouldn't be in the system?
I'm creating test cases based on the FSD (Functional Specification Document). Our FSD is composed of Requirements, Processes, and Fields for specific modules. While executing my test case, I have encountered a button that isn't in the FSD. How should I create a test case for this?
I am thinking of something like "System must not have buttons that aren't stated in the FSD" but that seems wrong.
I'm kind of new in QA, and in our company, we have a standard to use the word "System must, System must not, User must, or User must not" in all of our test cases.
