How did you conduct testing of your solutions in your previous position?

For testing solutions in the previous position, I used several approaches:

• Unit testing: I wrote tests using unittest or pytest to verify individual functions and classes to ensure the logic works correctly.

• Integration testing: I checked the interaction of multiple components together, such as working with databases or external APIs.

• Testing with test data: I created sets of test data with known results to verify processing accuracy.

• Test automation: I integrated tests into CI/CD pipelines for regular execution and quality control.

An example of a simple test with pytest:

import pytest

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.
