What is Unit Testing?
Unit testing is a software testing method that verifies individual units of code, typically functions or methods, in isolation to confirm each behaves as expected. Written and run by developers and usually automated with frameworks like JUnit or pytest, unit tests catch bugs early and make code safer to refactor and maintain. Introduction Jacob Kaplan-Moss,…
