Comparative Study on Software Testing Techniques?

Software testing is the process of evaluation of a software item to detect differences between given input and the output which is expected. Also to assess the feature of a software item, testing assess the quality of the product. Software testing is a process which is to be done during the development process. In other words software testing is a validation and verification process. Executing a system in order to establish gaps, errors or missing requirements in contrary to the actual desire or requirements is testing. White Box (or glass box) testing is the process of giving input to the system and checking how the system processes input to generate the output. Black Box testing is the process of giving input to the system and checking the output without bothering how the output is generated. White Box and Glass Box Testing combined to produce the Gray Box Testing. In this, the tester has little knowledge about the internal working of the software. So the testing of the output as well as the process carried out to generate the output. Software testing is a method of assessing the functionality of a software program. And Software testing has been classified into two main categories, dynamic testing and static testing. In this survey paper we discussed what is Testing, Terminology used in Testing, Levels in Testing and Comparison of Manual and Automation Testing, Comparison of Selenium and QTP tool and Comparison of Black, White and Gray box Testing.
