Beneath traditional development techniques, the absence of an automated, in depth device-test suite meant that this kind of code modify, assumed harmless via the developer, would have been still left set up, appearing only in the course of integration testing – or even worse, only in manufacturing; and analyzing which code change brought on the trouble, among the the many changes created by all of the developers throughout the months or perhaps anonymous months past see this to integration tests, was a formidable endeavor.
