What is Bug Life Cycle in Testing: Complete Guide for Tester

Many new testers do not know how a bug moves from finding to fixing. This can create confusion in testing work and make it hard to track software problems. The bug life cycle in software testing helps testers understand each step of a bug. It shows how bugs are reported, checked, fixed, tested again, and finally closed.

In this blog, you will learn the full bug life cycle in software testing simply. You will understand different bug status stages, how testers and developers work together, and why the bug life cycle is important in QA testing. This guide is easy for beginners and helpful for every software tester.

What is bug life cycle?

The bug life cycle is the life of bug from its identification to its closure. The bug life cycle would be different for different companies, it basically depends on the process followed in that company. It’s a lot easier for teams to know where a bug sits and it’s made the software better and safer for our users. The well-defined bug life-cycle is equally supportive in letting testers and developers collaborate in a straightforward and organized manner. Many organizations adopt this process in their contemporary software testing offerings to enable the saving of precious time, minimizing the chances of errors and raising the quality of software even before it is all set to be put in our hands.

Main Stages of Bug Life Cycle

The main stages of the bug cycle in software testing help teams track and fix software problems step by step. Every bug moves through different stages until the issue is solved completely.

Many companies use Manual and Automated testing services to manage bugs in an easy and organized way. Each stage helps testers and developers understand the bug's current status.

1. New

When a tester discovers a new defect in the application, the bug is set to the status of New. The tester provides everything related to the bug such as screenshots, error messages and steps to reproduce the bug. This is the initial phase of the bug life cycle. The testing team validates the bug before it goes back to developer team.

2. Assigned

After checking the bug, the testing manager or lead assigns the bug to a developer. The developer becomes responsible for fixing the issue. In this stage, the developer studies the problem and understands what caused the bug in the software.

3. Open

The developer starts working on the assigned bug, and the bug status changes to Open. This means the developer is currently fixing the issue. The developer may also discuss the bug with testers if more details are needed to solve the problem correctly.

4. Fixed

Until the developer fixes the issue, the bug status remains as Fixing. The developer modifies the code and hands the software to the testing team. This mark indicates that the developer thinks the issue has been fixed and is ready for testing again.

5. Retest

During the retest phase the tester tests the software for the second time to check that the bug is properly fixed. The tester reproduces the same actions as before and checks if the problem persists. This process is very crucial as it again ensures the quality of the fix.

6. Verified

If the tester is confident that the issue is fixed completely and the bug is working as intended bug status is changed to Verified. That means the testing team was able to verify the software, and the previous problem is no longer an issue.

7. Closed

Once verification is successful, the bug is marked as Closed. This is the final step in the bug life cycle. It means the bug is fixed entirely and there is no further action left. The bug report remains logged for future reference.

8. Reopened

Occasionally, following retesting, the tester still identifies the same issue. Consequently, bug status changes to Reopened. It means that the problem is not solved right and it should be sent back to the developer to fix it again.

9. Rejected

If the developer thinks it is not an actual bug, a bug may be labeled as Rejected. This can occur if the software worked according to its design, or the tester made an error in reporting the problem.

10. Deferred

When the team agrees to fix the issue at a later time, the bug status is set to Deferred. This usually occurs if the bug is very minor or not really affecting the software that much. It can be solved in a future software update, if the team so wishes.

Difference Between Bug Life Cycle and Defect Life Cycle

Bug Life Cycle

• The bug life cycle is the process a bug follows from finding the issue to fixing and closing it.
• In the bug life cycle, testers and developers work together to manage software problems step by step.
• It is during the software testing the application is not working properly that a bug is generally found.
• Types of the Bug Life Cycle include New, Assigned, Open, Fixed, Retest, Verified, and Closed.
• This process helps teams track bugs in an easy and organized way.
• Many companies use mobile app testing services to detect software bugs and improve app performance for users.

Defect Life Cycle in Software Testing

• The defect life cycle in software testing is the complete process of handling defects from detection to closure.
• A defect means the software is not giving the expected result or behavior.
• The defect life cycle in software testing helps testing teams understand the current status of every defect.
• This process includes the states New, Assigned, Open, Fixed, Retest, Reopened and Closed states.
• The purpose of the procedure is to make software stable, safe, and without error for the user.
• Test engineers and developers leverage this process to efficiently address issues and enhance the performance of the software.

Benefits of Proper Bug Life Cycle Management

A proper bug defect life cycle helps testing teams track, manage, and fix software issues in an easy way. The bug life cycle in testing improves communication between testers and developers and helps deliver better software to users.

Many companies also use Performance testing services to manage bugs properly and improve software quality before launching the product.

1. Better Bug Tracking

An efficient bug life cycle allows the teams to keep track of every bug from its birth to the end. Testers can tell at a glance if the bug is a new bug, a fixed bug, or closed one. This eliminates confusion and makes the process of testing more manageable.

2. Faster Bug Fixing

Developers can get a clear understanding of the issue-bug through these predefined stages and fix the bugs faster. This enables teams to save time and finish their software projects on time.

3. Improved Software Quality

Bug life cycle in testing eliminates software issues before users ever encounter it. This makes the software more stable, smooth and user-friendly.

4. Improved Team Communication

A well-defined bug control process promotes better communication between the testers, developers and managers. Now everyone is aware of the current status of the bug and what the next work is.

5. Fewer Software Errors

Bug defect life cycle also assists teams retest fixed bugs properly. This helps to reduce the likelihood of older bugs returning and build more bug-free software.

6. Better Customer Satisfaction

When software functions properly and without major errors, users have a better experience. Effective bug treatment also enables companies to produce high-quality applications that customers can rely on and use with ease. 

Common Challenges in Defect Life Cycle Management

Defect management is a critical component of software testing, but teams may encounter a wide range of obstacles during the process. It's also easier to understand the movement of defects from discovery to correction when teams articulate the defect life cycle well.

1. Lack of Proper Communication Between Teams

There are cases when defect details are not clearly communicated between testers and developers. This may confuse users and delay the process of fixing. Good communication is very necessary to have defects managed appropriately.

2. Incomplete Defect Information

Lack of information such as screenshots, steps or error details from testers can make it harder or impossible for developers to understand what the problem in the defect is. Defect fixing is slow and difficult for the team.

3. Delay in Bug Fixing

Some defects take more time to fix because developers may be busy with other work. In many software development services, delayed bug fixing can affect project deadlines and software quality.

4. Reopened Defects

The problem is that sometimes a bug is fixed but still exists when you retest because it was never resolved in the first place. The tester reopens the defect and the developer has to work on it again. Test time and costs of projects are increased by this.

5. Wrong Defect Priority

Teams may sometimes give low priority to important defects. This can create bigger software problems later and severely affect the user experience.

6. Difficulty in Tracking Defects

It is difficult to track all the defects when a project has too many defects. If the procedure is not well controlled, the teams may miss updates or, as a result of update overload, forget what current status the defect is.

Example of Bug Life Cycle in Real Project

In a shopping mobile app project, tester Riya found a problem where users could not complete payment after adding products to the cart. She reported the issue with screenshots and steps, and the bug status became New. The testing lead checked the issue and assigned it to developer Aman, so the status changed to Assigned. Aman started working on the issue, and the status became Open. After fixing the payment problem, he updated the status to Fixed. Riya tested the app again and found that the payment page was working correctly, so the status changed to Verified. Finally, the bug was marked as Closed. This is a simple bug life cycle in software testing with example that shows how testers and developers work together to solve software problems in real projects.

Future of Life Cycle of Bugs in Software Testing

The software bug life cycle is accelerating and becoming more intelligent and automated. Using modern testing tools, emerging technologies and innovative approaches, teams are identifying and resolving bugs faster to increase software quality and the user experience.

1. More Use of Automation Testing

In the future, software teams will rely increasingly on automation tools to find bugs sooner. Automated testing also enhances the software testing process and reduces the amount of manual work.

2. AI will Locate Bugs

Artificial Intelligence (AI) will assist testing teams in locating software bugs much faster and with higher accuracy. AI tools can analyze the software behavior and detect more hidden problems than end users.

3. Quicker Bug Tracking Systems

In the future, bug tracking will be smarter and easier to use. Teams will receive bug status updates in real-time, allowing developers and testers to collaborate better.

4. Improved Software Quality

Software bug life cycle enables companies to develop more secure and seamless software applications. With improved bug tracking, there will be a decreased number of errors and a more reliable experience for the users.

Conclusion

Each stage of the lifecycle, from bug detection to bug closure, is vital to enhancing software quality and providing users with a better experience. An efficient bug tracking process also means that teams can save time, eliminate errors and deliver more reliable software products.
