Uzair-Manzoor / Testing-Practice

Practical tests for JavaScript functions using the Jest library to make sure the AAA pattern has been followed. The purpose is to make tests easier for other developers to read and understand. Also TDD approach is been practiced

Test

This repository contains JavaScript functions and corresponding tests written using the Jest library. The tests follow the AAA (Arrange-Act-Assert) pattern and aim to ensure the correctness of the implemented functions.
