Gourt > Computers > Programming > Software Testing (10)
Software testing is the process used to help identify the correctness, completeness, security and quality of developed computer software.Testing is a process of executing a program or application in the intent of finding errors. With that in mind, testing can never completely establish the correctness of arbitrary computer software. In other words, testing is criticism or comparison, that is comparing the actual value with an expected one.
There are many approaches to software testing, but effective testing of complex products is essentially a process of investigation, not merely a matter of creating and following rote procedure. One definition of testing is "the process of questioning a product in order to evaluate it", where the "questions" are things the tester tries to do with the product, and the product answers with its behavior in reaction to the probing of the tester. Although most of the intellectual processes of testing are nearly identical to that of review or inspection, the word testing is connoted to mean the dynamic analysis of the product—putting the product through its paces. The quality of the application can, and normally does, vary widely from system to system but some of the common quality attributes include reliability, stability, portability, maintainability and usability.A good test is the one which finds an as yet undiscovered error. Refer to the ISO standard ISO 9126 for a more complete list of attributes and criteria.
Introduction
In general, software engineers distinguish software faults from software failures. In case of a failure, the software does not do what the user expects. A fault is a programming error that may or may not actually manifest as a failure. A fault can also be described as an error in the correctness of the semantic of a computer program. A fault will become a failure if the exact computation conditions are met, one of them being that the faulty portion of computer software executes on the CPU . A fault can also turn into a failure when the software is ported to a different hardware platform or a different compiler, or when the software gets extended. More on [ Software testing ]
