Agile software lifecycles comprise short iterations, with working software released at the end of each iteration. Agile testing approaches will be shaped by the test-driven, iterative, and incremental approach in agile projects. In this course, you'll learn about the principles underpinning agile development and some of the principle agile methodologies. You'll also learn about testing in the agile context and the skill set that an agile tester should have. This course is one of a series intended to align with the Agile Tester Certified Tester Foundations Level Extension Syllabus. The authors, Rex Black, Anders Claesson, Gerry Coleman, Bertrand Cornanguer, Istvan Forgacs, Alon Linetzki, Tilo Linz, Leo van der Aalst, Marie Walsh, and Stephan Weber, and the International Software Testing Qualifications Board or ISTQB® are the source and copyright owners of the Syllabus.
