In our recent article, we talked about bug tracking and software that helps to automate this process. There’s also another notion called defect management. In this article, we’ll discuss the difference between the two activities and look closely into the defect management process and the tools used for it.
A bug is a problem resulting from an error in the code which impacts software performance or functionality. Some examples of such faults include functional, compilation, logical, and runtime errors, missing commands, or inappropriate error handling. Bugs are discovered in unit testing by software testers.
A defect is a discrepancy between the actual and the expected result of software. In other words, it is any deviation from the specifications. Defects are solved by developers on the development stage.
Defect management is a complex process that results in releasing high-quality software. Defect management process in software testing includes several stages:
The aim is to detect as many defects as possible before the customer does it. Once the testing team finds a defect, they make the development team aware of the fault. The development team takes the responsibility to fix it and gives the defect the status “accepted”.
According to the priority, the development team fixes the defect in four steps: assignment, scheduling, fixing, and reporting.
When the testing team gets the report, the results should be verified. Testers do regression testing to check if the defect is actually fixed.
When the defect is resolved and verified, testers change its status to “closed”. If it hasn’t been fixed properly, the defect goes back to the developer to work on it again.
The defect management process should be transparent to the management board. So, the testing team continuously reports to them about the whole defect situation.
The right defect management tool stimulates proper test coverage and promotes defect prevention in the future. There are certain features to pay special attention while choosing a defect management tool, such as ticket statuses, email notifications, usability, reporting capabilities, dashboard visualizations, and accessibility. According to Google Trends, the top five most popular tools are Jira, Trello, Asana, Mantis, and Manuscript.
You shouldn’t forget about another benefit any defect management tool brings to the whole software development process: it improves quality assurance. All you need to do is to trace the origin of the defect and make changes in the validation process and base-lining document. This way, you either eliminate the defect or will find it earlier, which saves time and money on the testing process.
