Who Was the Term's Originator? Software testing, to put it simply, is the process of determining if the actual results match the expected ones to ensure that a software product or application performs as intended. It makes sense that this phrase originated much later than the first mechanical computer, known as "The Babbage machine," which was created in 1822 by English inventor Charles Babbage. The history of system errors and setting up software testing to get rid of them started at that point, in the 19th century. Thomas Edison is credited with coining the term "bug" in 1878 after it was supposedly used for the first time. Despite specializing in hardware, Edison wrote a letter to a colleague that, where he first used the term "bug." The connection was ingenious, and it quickly spread throughout the globe as a phrase for software bugs: "It has worked flawlessly in every invention I've made. The first step is intuition, which is followed by a burst of difficulty. After that, this thing breaks down, and at that point, "Bugs," or small flaws and difficulties, appear. This requires months of intense observation, research, and work before commercial success or failure is assured. The Originator of Software Examination People made significant advancements in computer technology during World War II, creating potent electronic computers that could crack codes and learn the details of adversaries' communication. Grace Murray Hopper is credited for officially coining the terms "computer bug" and "debugging" in the history of software testing by the time the war ended in 1945.
Given that debugging is merely a portion of the entire testing process, there are undoubtedly many distinctions between software testing and debugging. Realizing this, engineers across the world started looking for a process that could both eliminate errors and ensure that the finished product performed as intended. The need of software quality assurance was originally highlighted in 1951 by Joseph Juran, who is generally regarded as the founder of software testing, in his book "Quality Control Handbook." Additionally, he described the quality planning, control, and improvement components of QA management. Regarding the history of software testing today, in 1957 Charles L. Baker made the first clear distinction between program testing and debugging in a book review. A year later, Gerald M. Weinberg established the first testing team for Project Mercury, the nation's first human spaceflight program. Subsequently, the lexicon of software testing evolved, evolved, and expanded until it became distinctly differentiated in Glenford J. Myers' 1979 book "Art of Software Testing." Errors are referred to as human mistakes there, just as they are today, and they result in software bugs that cause the program to malfunction or perform improperly. Current Testing Standards Mark Fewster and Dorothy Graham wrote the first book on software automation in 1999, covering all aspects of software test automation, including strategies and methods. Cem Kaner introduced the topic of software testing history in 2003 with his articles "The Power of "What If" and "Nine Ways to Fuel Your Imagination," which covered the usage of scenarios in testing. According to him, a scenario is a made-up narrative that is intended to guide someone through the application and features of a complicated system or problem.
