How to make a test function using pytest

Question

I don't know how to make test function. I have this function

import pytest

def added(a, b, c):
    d = b + c
    e = a + c
    f = a + b
    return (d, e, f)

added(4,6,7)

How I can make a test_function for this function.

Thanks for any help in advance

Answer 1

Try this:

def test_added():
    assert added(4, 6, 7) == (13, 11, 10)

Then execute your test function. If all test are correct, you should get something like:

1 passed in x.xx seconds
