Clean code is to produce code that is well-organized, easy to read and understand, and maintainable. A code which is cleaned follows best practices and principles of software development, such as naming conventions, error handling, and modular design, to ensure the code is efficient, reliable, and scalable. The goal of clean code is to make the codebase more manageable and to make it easier for developers to add new features and fix bugs.

“Clean code” is not a tough work, but applying “clean code” correctly and efficiently is totally a different and challenging issue. Therefore, grasping and understanding how to apply clean code properly becomes an important issue for every programmer. Using clean code well helps the codebase to greatly improve.

Using “clean code” in practical programming brings a lot of value with many practical benefits. The specific and accurate identification helps us partly understand the reason to apply clean code in programming. And especially for new testers, writing Automation Test code also needs to clean code so that the team understands better and is more effective for the QA team.

“Clean code” has many advantages. For instance, “clean code” makes the code simpler to read and comprehend for others. Since most programs are developed in teams rather than individually, it will be confusing for other team members if everyone produces the same code. This negatively impacts the project’s quality and irritates the reader.

The first instance of “clean code” might refer to variable naming. Originally about the variable name you can set it to whatever variable you want, for example, as x, y, z…. This does not affect whether your program can run or not. However, looking at the name of a variable like that, after a while, you may forget what the variable stores in it, let alone your teammates. That’s not to mention professionalism anymore.

About this topic, Novatesting would like to recommend a book named Clean Code – A Handbook Of Agile Software Craftmanship written by Robert C.Martin which makes many aspects related to clean code become clearer.
