Question

I have been programming in Python for a month but I have never written a test case. I am trying to write 2 test sets to the test decision of my following program:

#!/usr/bin/python3

def books():
    a = input("Enter number of books:")
    inp = int(a)
    if inp==0:
        print("You earned 0 points")
    elif inp==1:
        print("You earned 5 points")
    elif inp==2:
        print("You earned 15 points")
    elif inp==3:
        print("You earned 30 points")
    elif inp==4:
        print("You earned 60 points")
    else:
        print("No Negatives")

books()

How do I write 2 test sets to test the decision for this program? Thanks!

Answer 1

Edits for second version of the question:

def books(): 

    points = [0,5,15,30,60];    #  list of the points
    inp = 0;

    while inp < 0 or inp >= len(points):
        a = input("Enter number of books:") 
        inp = int(a)

    print("You earned",points[inp],"points") 

books() 

You will be able to avoid the list if there is a direct correlation between the number of books and the number of points, but I don’t know your algorithm for that.

If the values for inp were strings then you can use a dictionary instead of a list.
