Abstract


Software Testing is the process of identifying the correctness and quality of software program. The purpose is to check whether the software satisfies the specific requirements, needs and expectations of the customer .Software testing is the process to expose design, requirement and coding errors in the program. Testing is used to identify the correctness, completeness, security and quality of software products against the requirements of the user. It exhibits all faults, errors and flaws in the developed software. Software testing is aimed at evaluating the capability or usability of a program. It is a significant method of accessing the quality of software. Though a lot of advancements have been done in formal methods and verification techniques, still we need software to be fully tested before it could be handled to the customer side. There are a number of testing techniques are available to complete the task. Software testing is an important area of research and a lot of development has been made in this field. In this paper, all the software testing techniques have been described and compared. Some latest researches have been described in brief.  The concept of Software testing is gaining more and more importance in the future. There are many approaches to software testing, but effective testing is a process of investigation, not only a matter of creating and following route procedure. While It is not possible to detect all the faults in the software . This  problem in testing thus arise an  question  : what would be the  strategy we should adopt for testing?. In our paper, we have described and compared the three most prevalent and commonly used software testing techniques for detecting errors and faults. They are: white box testing, black box testing and grey box testing
