Are you frustrated with those constant, annoying bugs during your software development cycle? This is not new to developers, bug is the most hated word of programmers. It is not possible to develop software with zero bugs, but we can try to reduce them. 

These minor bugs sometimes can cause big troubles for both developers and users. To reduce the frequency of bugs in your codebase, you have to understand the nature and cause of these and find strategies to tackle them. You can use browser testing tools and bug testing tools for better results.

After consulting with various testers and developers, we have created a list of best practices that can help you prevent the reintroduction of bugs into your codebase.

5 Best Practices for Preventing Bugs Into Your Codebase

Fixing bugs is challenging as well as costly and time-consuming. If you are constantly getting bugs in your code, then fixing them can consume a lot of human and physical resources. 

As said by a Dutch philosopher “Prevention is better than cure”, reducing the count of bugs is always better than fixing them later. You can follow the below list of 5 best practices for preventing bugs.

Use Behavior-Driven Development (BDD):

Behaviour-driven development is a method of software development in which the application is developed and designed around the behavior users expect during their interaction with the application. 

The goal of BDD is to make the process of development simple by using a common domain-specific language. This helps in converting natural language sentences into executable texts.  BDD increases the visibility and collaboration among the team members.  

BDD projects usually begin with the interaction among developers, managers, and customers to form the overall picture of the application. The implementation of this method usually begins with the widest level of expertise and progresses to the bottom.

This process results in reducing the bugs and is available as one of the best ways of preventing bugs. 

Transparent Communication:

Every process of development needs good communication. Transparent communication among the developers, testers, and research team who are collecting the data on requirements is very necessary. 

When all team members are informed about the requirements and specifications of the application, they are more likely to solve the issues quickly and early. Professional developers always plan how and when they will solve the bugs. 

Some programmers start procrastinating to solve bugs, and they start shifting the dates for later. In this scenario, all team members and the team lead should communicate and decide a time to fix the bugs immediately. 

It is advised to frequently communicate with each other so you can discuss the frequent bugs and fix them rapidly.

Use Bug-Trackers:

Bug-tracking tools are very essential for software development because they help in identifying bugs quickly and increase your productivity. Bug trackers constantly give notification alerts to your team about the changes and modifications of bugs. 

You can organize your bugs using bug tracker tools and prioritize which bug you want to solve first and which one to keep for later. You can also use automated testing tools to decrease manual efforts and increase productivity. 

Bug trackers provide in-built chat features, which support developers in communicating about the bugs. When you are choosing a bug-tracking tool, you should keep in mind factors like budget, project size, number of team members, etc. 

This will help you select the perfect tool that can handle your bug volume and team communication. 

Do You Know?
Developers often talk about bugs in their daily development cycle. Do you know where the word bug came from, and who used it first? A moth got stuck in a Harvard Mark II computer in 1947. This caused a malfunction in the system. 
Then, the technician who resolved the issue named this as the “first actual case of a bug being found”. From there, this word got popular.


Code Refactoring:

Refactoring is the process of improving your code without changing its functionalities. The process of refactoring increases the quality of the code and reduces bugs. 

Refactoring makes your code more readable, and understandable and reduces complexities so that this code can be used again.  Refactoring makes the code more organized, which helps in fixing the bugs more quickly. 

Code refactoring also improves the performance of applications sometimes and that helps in running the application fast and using fewer resources. These are some of the best methods of code rendering:

  • Extract Method
  • Rename Variables
  • Remove Duplicate Code
  • Split Conditional Statements

Use Version Control:

Version control is a system that tracks and manages the changes and modifications of your codebase. Version control is considered an important skill for developers. This is helpful in both code writing and fixing the bugs. 

Version control provides the facility to track the history of your code and view different versions. It is an essential tool for debugging, you can see how the bug was created by viewing the changes in the code. 

When you are selecting a version-controlling tool for your project, you should select it according to the size and requirements of your project. Following are some of the best version control tools:

  • Git
  • Subversion
  • Mercurial

Final Note: 

Appearance of bugs is usual in software development. However, it is necessary to reduce them. When your development cycle has fewer bugs, it will increase your productivity and save time and resources. 

In this article, we discussed the best practices for the prevention of bugs in your code base. If you find this post helpful, share it with your fellow programmers, so that they also can use these tips to reduce bugs and increase productivity.
