W10_L4: Pytest

Welcome to Week 10 Lecture 4 of the course "Modern Application Development I" by Profs. Thejesh G N and Nitin Chandrachoodan. Full Course: https://study.iitm.ac.in/ds/course_pages/BSCS2003.html Video Overview This lecture introduces pytest, a powerful and opinionated Python testing framework. We explore how pytest simplifies writing and running tests, its helpful features like automatic environment setup and test fixtures, and how it compares to Python's built-in unittest library. Through practical examples, we demonstrate testing a function, handling exceptions, creating temporary directories, and using pytest to test a Flask web application. Learn how to create test fixtures and client requests to test your Flask endpoints. The lecture also shows how automated testing concepts can be extended for grading purposes.
