Agile methodology promotes an ongoing iteration of development and testing processes throughout a project’s SDLC. Here, the development and testing activities are performed concurrently, unlike the Waterfall model. The agile development emphasizes these four core values: Interaction of team and individuals over processes and tools Working Software over comprehensive documentation Focus on customer collaboration instead of contract negotiation Respond to change than rigidly following a plan To comply with these core values, the Agile development method has two prime bug tracking tools – JIRA and Bugzilla. Both of them are widely being used by a lot of organizations for quite a long time now. However, when pitted against each other, individual performance becomes a deciding factor. Let’s find out which tool is better in this comparative blog: Bugzilla Built by Mozilla, Bugzilla is an excellent defect tracking system that allows developers to keep a track of bugs. Being an integral part of the browser, it is known to record millions of bugs. Software is a competitive market with a lot of paid tools promising to deliver better results, but to this day Bugzilla remains free. Even though it’s free, it comes with several state-of-the-art features, which are not there in its expensive counterparts. It makes Bugzilla the favorite bug tracking tool of millions of developers across the globe. It lets users track defects, perform advanced searches, schedule reports, find duplicate bugs, file and modify bugs via email, track time, and send attachments and comments to other users. Bugzilla offers: Tracking abilities for both, alterations in code and bugs Easy communication Quality assurance Comprehensive permissions system Reviews and submits patches Integrated email capabilities Optimized database structure Bugzilla has a low learning curve, so it’s also beginner-friendly. For a more rigorous approach, one can enroll in Bugzilla training to be an expert in no time. JIRA This bug tracking tool was developed by an Australian Company, Atlassian. You can use it not only for bug and issue tracking but also for project management. Though it is a paid tool you can easily understand its working through various videos available online. JIRA is fundamentally an incident management tool; however, it is mostly used for bug tracking by software developers and testers. Jira offers: Out-of-the-box Scrum and Kanban functionality that allow you to easily scale agile practices. A flexible workflow engine to help you easily build the perfect process that fits the way your team works. JQL(Jira Query Language) to create a personalized view of Software. Build dashboards that track project status, house custom reports, and monitor team progress. REST and Java APIs Over 950 plugins and add-ons in the Atlassian Marketplace When we talk about workflow, Bugzilla allows admin to define a global workflow for all the products by just editing the transition matrix. Also, unlike JIRA, it allows users to choose the initial status of new issues. It further allows the admin to configure the transitions requiring comments. On the other hand, JIRA allows multiple workflows depending on the project and type of issue. In regards to access control, Bugzilla has flexible though mind-bending features for grouping issues, users, and granting permissions. However, the permission model is simpler in JIRA. It is more convenient and conventional. We work with both the tools as per client requirements but if we had to choose one, It’d be Jira. Just because of the customizations and usability advantages that Jira offers in an Agile ecosystem.
