This document discusses bugs in software, Bugzilla (a defect tracking system), and how to use Bugzilla. It defines a bug as an unexpected problem or flaw in a program. Bugs arise from human errors in specification, design, coding, or documentation. Common reasons for bugs include programmer mistakes, fatigue, or misunderstanding requirements. Bugzilla allows developers to track outstanding bugs and includes features like advanced search, email notifications, and customization. It is used by many organizations and open source projects to manage quality assurance and facilitate communication during software development. The document outlines how to create a Bugzilla account and login to begin using the system to submit and track bugs.

3. WHAT IS BUG?
 Unexpected Problem!
 Technically, a software defect
 Where from?
 Programmer’s mistake
 Tired!
 Misunderstanding problem definition
(user request)
 Low Quality Software!

4. HOW BUGS GET INTO SOFTWARE?
 A software bug is a failure or flaw in a
program that produces undesired or incorrect
results.
 They arise from oversights or mutual
misunderstandings made by a software team
during specification, design, coding, data
entry and documentation.
 There are many reasons for software bugs.
Most common reason is human mistakes in
software design and coding.
 For example, one might accidentally type a
"<" where a ">" was intended, perhaps
resulting in the words being sorted into
reverse alphabetical order.

5. HOW TO FIND BUG?
• Before Final Release (TESTING!)
• Bug is one of the result of testing
• Alpha Release
• Developers inside
• Beta Release
• Testers (volunteers)
• Let is hurt! (exit(-1))
• After Final Release
• Don’t let it crash the system! (try {} catch())

6. WHAT IS BUGZILLA?
• Bugzilla is a “defect tracking system”
that allows individuals or groups of
developers to keep track of outstanding
bugs in their product effectively.
• It was developed using free open
source tools and is itself free.
• Despite being free, Bugzilla has many
features its expensive counterparts
lack.
• Currently in use by Mozilla, Open
Office, Apache, Eclipse, Red Hat,
Nasa, AMD and many more!
