It is possible that software which is 99% bug-free is still unusable. The Pareto Principle explains a number of global phenomenons, one of them being how wealth is distributed in countries around the world such as the United States of … The course covers smoke testing, acceptance testing, Pareto principle, defect distributions, automated vs. manual testing… Especially it is typical for the most severe defects. During testing, it may happen that most of the defects found are related to a small number of modules. Principles of Software Testing - MCQs 1. Main Partner at Hathway Tech (United States).
