PyTest: compare strings

Comparing short strings also work relatively well as we humans will be able to read the error report.

def get_string():
    return "abc"

def test_get_string():
    assert get_string() == "abd"

$ pytest -q test_string_equal.py

Output:

F                                                                        [100%]
