Software testing: an activity being part of the software development process aimed at evaluating a software item (system, subsystem, unit etc.) features (functionality, performance etc.) against the given set of system requirements. Software testing implies running the software item in predetermined conditions (test case, test scenario), recording and analyzing the obtained results, and identifying errors (i.e. bugs), which means failure to satisfy a set of requirements to the software.
Software Testing: The process of devising a set of inputs to a given piece of software that will cause the software to exercise some portion of its code. The developer of the software can then check that the results produced by the software are in accord with his or her expectations.
Software testing is the process used to help identify the correctness, completeness, security and quality of developed computer software. With that in mind, testing can never completely establish the correctness of arbitrary computer software.
Software testing: is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test[1] , with respect to the context in which it is intended to operate. This includes, but is not limited to, the process of executing a program or application with the intent of finding software bugs.
A set of activities conducted with the intent of finding errors in software.
