Testing as a bottleneck – How testing slows down modern development processes and how to compensate We often claim the purpose of testing is to verify that software meets a desired level of quality. Frequently, the term "testing" is associated with checking for functional correctness. However, in large, complex software systems with an established user-base, it is also important to verify system constraints such as backward compatibility, reliability, security, accessibility, usability. The time spend on verification is a lower bound on how fast we can ship software. Anything we can do to increase the effectiveness and efficiency of test execution…....
