pytest is a robust testing framework for Python that simplifies the process of writing small, scalable tests. It offers detailed assertion introspection, auto-discovery of test modules and functions, and a rich plugin architecture, making it suitable for both simple unit tests and complex functional testing for applications and libraries.

Usage Example​

Here’s a simple example of a test function using pytest:

# content of test_sample.py

def inc(x):
    return x + 1

def test_answer():
    assert inc(3) == 5

To execute the test, run the following command in your terminal:

pytest

pytest will automatically discover the test function and execute it, providing a detailed report of the test results.
