The Essentiality of Software Testing

The process of evaluation and verification in order to see to it that the software product or the application in question is working in the desired manner to give the required output. Prevention of the occurrence of bugs, reduction in the costs of development, and bringing about improvements in the performance of the software product or application are some of the uses or benefits of software testing.

Software products that have undergone the testing phase can be considered to be more reliable, secure and also deliver high performance and all this taken together results in customer satisfaction, saves time as well as cost.
