Candidates learn about:

• Collaboration within agile teams

• Continuous feedback

• Incremental development

• User story testing

• Shift-left testing

• Faster release cycles

Agile testing requires strong communication and adaptability because testing occurs continuously throughout development.

Testers in agile environments work closely with developers, product owners, and business stakeholders.

Importance Of Defect Management Skills

Defect management is a critical part of software testing.

Candidates learn how defects are:

• Identified

• Recorded

• Classified

• Prioritized

• Tracked

• Verified

• Closed

Effective defect management improves communication and supports efficient issue resolution.
