What types of testing have you implemented in your project?

In my projects, I have implemented several types of testing:

• Unit testing — testing individual functions and classes using libraries like pytest.
• Integration testing — testing the interaction between components, such as tests involving databases or external services.
• Functional testing — testing business logic and usage scenarios.
• API testing — using tools like Postman or automated tests with requests.

An example of a simple unit test in Python with pytest:

import pytest
from mymodule import add

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

This approach helps identify errors early and maintain code quality.
