To be successful, test managers must keep pace with the constantly changing world of software development. The test manager’s job description—planning, supervising, and reporting the activities of the test process, with a focus on functional black-box tests—has remained virtually unchanged over the past decade. Meanwhile, the job requirements have changed dramatically—fast release cycles leading to widespread adoption of agile methodologies; increased security, performance, and usability requirements; and myriad smart devices in users' hands. And these are just the most obvious. Silvio Moser explains how these trends change the way we develop and test software, and describes strategies for tackling these challenges. Test managers must adapt to a new test management curriculum and a transformed role—the test master. While the classic test manager is mainly organizing and controlling, the test master acts as a mediator, moderator, and problem solver. Learn to stop managing and start mastering.
