A class grade application for instructors assigns letter grades based on students' numerical grades.

The letter grades for different numerical grades should be:

Above 89, up to 100 - A

Above 79, up to 89 * B

Above 69, up to 79 * C

Above 59, up to 69 - D

Below 60 - F

Which of the following sets of test inputs would achieve the relatively highest equivalence partition coverage?

Show Suggested Answer Hide Answer
Suggested Answer: D

The Testing Quadrants model helps Agile teams by categorizing different types of tests and their purposes. This differentiation helps test managers explain the testing strategy to all stakeholders, ensuring everyone understands the scope and objectives of each test type. This model aids in planning, executing, and tracking testing activities across different quadrants, making it easier to align with stakeholders' expectations and project goals.

I’m leaning towards option D because it covers a wider range of grades, but I’m not entirely confident.

I think option C might be the one since it includes grades from A and B, but I need to double-check the others.

I think I see what they're looking for. The goal is to test the edge cases between the different letter grade ranges. Option C seems to do that the best.

Okay, I've got this. The key is to choose the set of test inputs that covers the boundaries between the different grade ranges. Option B looks like the best choice to me.

This seems straightforward - I just need to identify the set of test inputs that covers the different grade ranges. I'll think through the options carefully.

If you get an F, do you just have to accept your fate and become a professional 'F' collector?
