Bugzilla Review and Overview

Bugzilla is a recognized bug testing and tracking system over a cloud interface. It was developed by Mozilla in 1998, as an open-source project. It is one of the robust, full of features and user-friendly bug tracking products. It houses the best defect tracking tools, which can be installed in multiple systems. Users can use external integration to enhance the workability of Bugzilla with visibility control, custom fields, and workflow management.

It is used by even big organizations like Mozilla, WebKit, Apache, Red hat, LibreOffice, etc. Since the platform has a self-hosting cloud UI, it can be accessed anywhere. The last stable release was Bugzilla 5.0.6 in February 2019. As for requirements, it needs a stable DBMS, Perl 5 compatible web server, and a mail transfer agent or SMTP server.

How Does Bugzilla help in Defect Tracking?

One version is for users, and the other is for administrators. Both have different operative tools and methods. The first step to use Bugzilla is by making an online account on their site and start by filing and editing a bug.

For Users, Bugzilla has advanced search capabilities, reports/charts, scheduled, and multi-format support. There are some advanced email functions like auto-notifications and bug modification/filing. It has automation for duplicate bug detection, username completions, and user-lists. Sharing features like private attachments, comments, user monitoring, and share searches are present too.

As for Administrator tools, Bugzilla is more inclined to manage features. It uses advanced security features like taint mode in Perl, to prevent cross-site scripting. Encryption is also present here. It supports custom field database for searching and capturing the bugs. It has preset lists of statuses, workflows, and resolutions, which are all customizable. The admin feature even includes full Unicode support and has multi-language support.

It can work on mod_perl from Apache, improving overall performance. Other than this, advanced admin tools like XML-RPC & JSON-RPC interface, bug visibility, users impersonating, multiple secure authentication methods, support for several DBMS, and sanity check for data inconsistencies are also present.

As seen, Bugzilla truly offers a comprehensive bug testing platform with open source code and a stable work environment. It is also usable by business and private firms without the worry of cost.
