Analysis of black box software testing techniques: A case study

Software testing is a process of verifying and validating that a software application or program works as per the users expectations. It is used to find out the important defects, flaws, or errors in the application code. In this paper we have developed a tool to generate different test cases automatically. To show the validity of the tool, we have considered the line equation problem and generated different test cases, and finally we conclude that Robustness Technique is better than Boundary Value Analysis, because the expected output (number of times) in case of Robustness Technique for intersecting lines, parallel lines and coincident lines are 12, 12 and 1 respectively while in case of Boundary Value Analysis it is 8, 8 and 1 respectively.
