Importance of Software Testing in the Process of Software Development

Software Testing is the process to check whether the software is defect- free or not. It is the process of verification and validation of software service or application by checking whether it is meeting the user requirements and what all is implemented as per the characteristics. Software testing plays a vital role in the process of developing a high quality software. Testing is necessary because we all make mistakes. Some of those mistakes are unimportant but some of them are expensive and dangerous. Therefore, there is a need to check everything that we produce. Hence, this paper presents an introduction to Software Testing and its importance with strong exemplary illustrations. It not only provides a vivid account of the need, objectives and principles of testing but also summarises traits of an excellent Software tester. At last, this paper includes a comparative study of present scenario of software testing with regard to testing in early days. Moreover, this paper focuses on "Why to test" not How to test, so that the need of carrying out Software testing can be crystal clear in a more effective manner.
