Agile testing is a relatively new approach to software testing that follows the principles of agile software development as outlined in the Agile Manifesto.
A tester on an Agile project will work differently than one working on a traditional project. Testers must understand the values and principles that underpin Agile projects, and how testers are an integral part of a whole-team approach together with developers and business representatives. There is a lot of confusion concerning agile testing – which means there's an educational opportunity as well.
The Agile Extension will give the tester the knowledge to be part of agile testing teams and achieve high performance.
