In this overgrown DevOps market, finding the best tools and applications to kickstart your software development project must be challenging. This article will help you understand code refactoring in DevOps, how to get the right tools for this purpose, and some of the best tools for refactoring codes in the market.      

What Is Code Refactoring in DevOps?

Code refactoring is the process of improving the quality of the code of software by changing some of its parts, deduplicating the code base, eliminating unnecessary dependencies, and so on. In DevOps, you refactor a code just after the test-driven development (TDD) cycle to make the code maintainable and compact without changing the external behavior of the program. 

If you follow behavior-driven development (BDD) or acceptance test-driven development (ATDD), you need to do code refactoring. 

Looking for reliable tools for TDD, BDD, and ATDD? Check out the best test-driven development (TDD) tools.

Refactoring the software code is an indispensable part of Agile and DevOps software development. It enables business-driven software developers to pay off the technical debt before rolling out the product so that they can avoid major software breakdowns when it is in the public domain. 

Martin Fowler is the pioneer of the code refactoring concept. He explained refactoring code in detail for businesses and software developers in his book “Refactoring: Improving the Design of Existing Code”. You must read it if you are in the software development business.    

When to Consider Refactoring Code

Most DevOps projects include a code refactoring schedule when adding new features or updating the software. You could also go with refactoring code when reviewing the program code monthly, biannually, annually, etc.

It is worth noting this is your last chance to correct and optimize the code before the software or service goes live. There are Agile software development projects that also implement a frequent code refactoring schedule.

Find below some tips on when to refactor your software code:

  • Logic repetition or circular code structures are observed.
  • Multiple developers face challenges in comprehending the code and its functionality.
  • Issues arise with a specific portion of the code.
  • Debugging processes take longer than expected.
  • Random debugging occurs due to a lack of a comprehensive method to tackle issues.
  • The last code refactoring was done a while back and is now due for an update.
  • There are plans to add a significant feature, component, large block, or integrate with a third-party solution.

Best Practices of Code Refactoring

Find below the handy pointers on code refactoring practices:

  • Refactor codes regularly to maintain code quality and also reduce technical debt.
  • Minimize the risk of adding unnecessary bugs by refactoring the codebase in small chunks.
  • Do not forget to validate the functionality of the codes against the required external behavior after refactoring codes.
  • Follow the eat the frog approach in a refactoring project. It means prioritizing areas that affect multiple parts of the codebase or are difficult to understand.
  • Use a version control software or web app to maintain different versions of the refactored code and go back to the best-known version when needed. 
  • The code refactoring project must involve everyone from the DevOps team.
  • Create a code refactoring document or logbook and record the reasons and approach behind each refactoring session for future reference. 
  • It is recommended to refactor code when reviewing the software, mobile app, or web app for audit purposes. 

Consider automated refactoring tools to expedite the process and maintain consistency.

Validate refactored code through comprehensive testing and performance analysis.

Benefits of Code Refactoring

Without code refactoring, you would keep adding functionalities to the existing software code base. When the code becomes super complex and unmaintainable, you get rid of it and start from scratch. 

But, when you start refactoring your software codes, you make them efficient to deliver current business value and keep the code compatible to include future business values without developing from scratch.

Find below some common benefits of code refactoring in DevOps and Agile:

  • Enhances code quality and readability, leading to easier maintenance and troubleshooting
  • Reduces technical debt and minimizes the risk of future bugs and errors
  • Improves the overall efficiency and performance of the end product or service
  • Facilitates the inclusion of all feedback and comments from the entire DevOps team via collaboration
  • Keeps your software codebase modular so you can easily add or remove features in the future
  • The code refactoring process creates a standard development practice
  • Your software or mobile app becomes scalable
  • It promotes the continuous improvement culture in DevOps
  • New developers can easily understand the codebase when existing ones exit the project

No, let us see below the code refactoring tools that the most successful DevOps project use:

SonarLint

SonarLint is a popular code refactoring tool that seamlessly integrates with many Integrated Development Environments (IDEs). It lets developers identify and address code quality issues in real time.

By analyzing the code on the fly, SonarLint detects bugs, security vulnerabilities, code smells, and maintainability concerns. Such code quality reports aid developers in making immediate improvements. With its 5,000+ coding rules and issue data flow, SonarLint ensures consistent code quality across projects.

IntelliJ IDEA

IntelliJ IDEA offers expansive code refactoring features to enhance code quality and maintainability. Its intelligent code analysis enables you to instantly identify potential issues and apply various refactoring techniques. It also provides automated refactorings for tasks like renaming variables, extracting methods, and introducing variables. 

Furthermore, you can perform advanced refactorings, such as extracting interfaces and moving members to different classes. Preserving code integrity and functionality is a real challenge when driving code refactoring. IntelliJ IDEA offers the means to address this risk using features like Preview refactoring changes and Resolving conflicts.  

Visual Studio Code

Visual Studio Code by Microsoft has a market share of 41.16% in the IDE market. This is a major IDE on which most DevOps projects develop their codebases. Its code refactoring capabilities are also next to none.

It has many built-in refactoring actions as well as support for third-party code refactoring integrations from the VS Code marketplace. Some of its built-in refactoring actions are Extract Method, Extract Variable, Rename symbol, etc.
