What testing methods were used in your team?

In our team, the following methods were used for testing Python code:

• Unit testing — testing individual functions and classes using frameworks like unittest or pytest.
• Integration testing — testing the interaction between modules, such as database operations or external API calls.
• Functional testing — testing business logic and user scenarios.
• Mock testing — using mock objects to isolate the components under test.

Example of a simple unit test with pytest:

import pytest

def add(a, b):
    return a + b


def test_add():
    assert add(2, 3) == 5

This approach allows for quick error detection and maintaining code quality.
