let’s say there is a Shape interface.
interface IShape { double Area(); }
A Rectangle class and a Triangle class implement it. Now should i write tests for:
- IShape interface and test both implementations in a single test file?
- Write tests for Rectangle and Triangle class separately, testing their implementation of Area() ?
- Do something else?
From what I see I am testing implementations either ways. How do you even test an interface without testing the implementation? Can someone please help clarify my doubts? Thanks!
No problem! I thought there was a good chance you already know the concept, just not in the exact, unfortunately-overloaded words of your post title.
