Bug tracking is the process of identifying, recording, and managing software defects.

Explanation:

• A bug tracking system (e.g., Jira, Bugzilla) helps developers log and resolve issues efficiently.
• Bugs are classified by severity (critical, major, minor) and priority (high, medium, low).
• It includes reproducing the issue, debugging, and fixing it.

Bug Lifecycle:

1. New → Identified & reported.
2. Assigned → Given to a developer.
3. In Progress → Being fixed.
4. Resolved → Fixed & tested.
5. Closed → Verified & marked complete.
