I’m currently working on a college assignment that requires me to do unit testing in python. The program I need to do unit testing for was very simple to make; I just needed it to take an input of two numbers, and then output the smaller number of the two, followed by the larger one.

I’m a bit confused on how to unit test this though. I can unit test in python by having something like:

    result = 3 + 7
    test1.assertEqual(result, 10)

However, I need something more like:

    input_a = 3
    input_b = 4
    test1.assertEqual(answer(input_a, input_b), 3, 4)

In a case like the one above, ‘answer’ is a function that checks which of the two numbers are bigger and smaller, and then returns them accordingly. For example, if ‘answer’ takes two numbers ‘a’ and ‘b’, where a > b, then the ‘answer’ function will end with ‘return b, a’.

I’ve tried the second code sample that I gave above, but it does not seem to work, as running the test gives an assertion error: AssertionError: (3, 4) != 3 : 4

Does anyone have any ideas on how I can or need to format a unit test that tests a sequence of two numbers? If so, I would appreciate it.
