The ISTQB® Advanced Level Agile Tester (CTFL-AT) certification provides the key testing skills necessary to successfully contribute to an Agile project. CTFL-AT covers agile testing in alignment with 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.
