An comprehensive study of software Testing and its Techniques

IEEE definition of software testing is process of executing the program with specific intent of finding errors. Software testing remains the primary concern used to gain consumer’s confidence in the software. Ideally, testing of software guarantees the absence of errors in the software, but in reality it only discloses the presence of software errors, but never guarantees their absence. Even, systematic testing cannot guarantee the absence of errors, which are detected by discovering their effect. Software testing also identifies important defects, flaws, or errors in the application code that must be fixed. The modifier “important” in the previous sentence is, well, important because defects must be categorized by severity. In this chapter, we will provide introduction to various basic principle and key terms which are used in software testing.
