This article outlines the significant causes of software defects and how a software defect tracking tool can help in finding and fixing software defects quickly. 

Bug-free software is a prerequisite for a successful software release. Many testers are always finding ways to resolve bugs and working on methodologies for bug-free software. 

Testing has transformed over time, it is not limited to checking the validation and outcome of various software components. It now checks the end-to-end lifecycle of software development from business requirements to user acceptance. Companies are working on agile and lean methodologies to deliver fast-paced applications in a strict schedule for shorter time to market.

There is a list of defects causing factors in code. Knowing these factors can help testers and developers in reducing the number of errors in code. 

1. Misleading requirements which lead to errors in code 

Requirements are the foundation for any software. Any inaccuracy or deviation from the actual is mapped to the software causing errors. It is the most common issue faced by developers as it impacts the entire software development lifecycle.

Also, miscommunication among a team of developers is a significant cause of errors in the software. Team collaboration is required to ensure the smooth and timely delivery of software. 

2. Unrealistic timelines for development 

Mostly, developers don’t get enough time to design and develop and unit test software in a development environment before moving it for testing. So developing a project on an unrealistic project leads to critical errors affecting quality and performance. 

3. Lack of expertise in team

The visuals of the software play a vital role in the development of design and codebase. The design decides various aspects of software development. Developing software in strict timelines where sometimes implementation can take more time or project requires more time. Timely completion of development ensures

So performing everything timely is important to understand the bugs and problems. Completing everything in specific timelines can cause more errors. 

4. Human factors leading to errors in code 

An unhandled exception which is not defined also causes errors leading to bad code. It means the code has improper validations and inputs which gives incorrect results. Developers are using faulty compilers and validators, which add more errors to the code. These errors are tricky to remove. 

5. Third-Party tools 

There is a list of third-party tools that introduce errors in the code and are used by developers. Developers use tools such as HTML Editors, plug-ins, external APIs, Class libraries, shared DLLs, Compiler, and Debugger. It is essential to track the security concern as some can inject the virus in the software, which causes failures.

6. Last-minute changes in requirements 

Changes in requirements in the last hour lead to unreliable software applications. The changes should be implemented before to check its impact on code and errors caused due to deviation. 

7. Lack of version control 

Creating various changes and losing control of the latest version causes software defects. A software defect tracking tool is required to log the errors, monitor their changes, and track them. The team will get notified when any changes are done. The bug can be assigned to the developer to fix and update. The tool simplifies the entire bug tracking process. It also helps in maintaining various versions of the software. 

8. Poor testing 

Inability to write accurate test cases which covers all scope of the software leads to errors. Unskilled testers or negligence while testing introduces more errors in the software. 

Conclusion:

The right testing strategy should be implemented with a useful bug tracking tool to reduce the risk of failure.  Testers should have a fair understanding of factors causing defects. Automation testing can also be used to release a high-performing software.
