Testing demo: pytest using classes - failure

Here too we can add additional test-functions to the same test-class. Executing pytest will print .F indicating one passing test-function and one failing test function. We'll get detailed explanation where the failure happened.

The exit-code will be different from 0 helping the CI systems and any other external system to know that the tests have failed.

import mymath

class TestMath():
    def test_math(self):
        assert mymath.add(2, 2) == 4

    def test_more_math(self):
        assert mymath.add(3, 3) == 6
