How was testing carried out in your projects?

In my Python projects, testing was carried out using unit tests, most often with the unittest or pytest library. I wrote tests for key functions and classes to verify their correctness with various input data.

Integration testing was also used to check the interaction between system components. Automated testing was performed using CI/CD pipelines that ran tests on each commit.

An example of a simple test using pytest:

# test_example.py

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


def test_add():
    assert add(2, 3) == 5
    assert add(-1, 1) == 0

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