Software systems have become an integral part of our life. Most of us have had experienced software failures where software did not work as expected. Software that does not work correctly can lead to severe consequences, including financial loss, loss of time, or business reputation, and even injury or loss of human lives. Software Testing provides an independent view of the software product. This article will provide you with a comprehensive knowledge about Software Testing, it’s types, importance, techniques/methods and process.
What is Software Testing?
Software Testing can be defined as the process of examining a software system to check whether it conforms to the specified requirements and finding bugs to ensure that the software is defect free which in turn leads to quality software product.
Software Testing can also be stated as the process of validating the software product after its development gets completed according to Verification and Validation model. It is one of the activities which is performed under Quality Control (QC).
According to ANSI/IEEE 1059 standard, Testing can be defined as: A process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item.
According to IEEE 610.12, 1990, Software Testing is the process of exercising or evaluating a system by manual or automatic means to verify that it satisfies specified requirements or to identify differences between actual and expected results.
According to ISTQB, Software Testing is a way to assess the quality of the software and to reduce the risk of software failure in operation.
