They allow us to extend and refactor our code with ease. Many developers follow test driven development as a workflow. I believe that writing tests makes software development much more interesting and generally leads to better code. Well-designed and tested systems are easier to maintain. Over the last few years, developers have begun to put a lot of application logic in the browser. The Testing Setup Let’s discuss the types of tools that make testing possible.
