Over the past few years the technological advancements have completely changed the way people deal with every day information. At this point, it has become very clear that the process of building software consists of several different steps. The rapid growth, among with the huge need for better software, allows this study to further examine a part of this process called “Testing”. Testing practices are a subset of quality assurance (QA), which is there to ensure that a particular service/application meets some standards. It’s a vague term, that is often misunderstood and even naively left out of the process. “Software testing is any activity designed to reveal the presence of faults in software." There can be software that contains no faults, but if the application requires user input then it is impossible to perform exhaustive testing (where all possible inputs are tested) to prove that there are no issues. Hence, since it cannot be proved, it is very likely that it will contain faults, commonly known as bugs.
Testing highly scalable services with high user retention is proven to be quite of a challenge nowadays and IT companies thrive to develop and optimize processes to create better and faster applications to satisfy their customer needs and offer a great user experience.
