I have always done these very simple test cases so I am actually very lost and got overwhelmed when I got this assignment where I should do test cases from a functional design specification document. Of course you have your introduction and purpose then there are different section and the section themselves have sub-sections (3.1, 3.2). One of the functions being example search, add, edit and remove in shopping cart on the website and other for an app. And then there is attachment with pictures of the prototypes showing these functions, diagrams, additional/subblementary specification, UI etc. It's a lot!
I don't really know how to tackle these. If I were to write for test cases for each subsection, I think there would be alot. How do I need to think and go about solving this? This might actually sound easy to many of you but I just started with testing (7 month ago). This is really interesting.
