One of the key issues that I have seen newbies make while working with test automation is they focus a lot on the tool but there is little to no attention on the design patterns.

To be honest design patterns are an important part of any test automation strategy. It’s like a well-organized recipe book in a kitchen. Each recipe represents a design pattern, providing a tried-and-true method for preparing a dish (or solving a problem in your code).

It helps to ensure that your code is flexible, maintainable, consistent, and efficient.

This article discussed the five most used design patterns, there are certainly more but today we are going to discuss:
