SOFTWARE ENGINEERING

Detailed explanation-1: -It is a huge list with more than 100 different types of testing that can be listed. Robustness testing is a quality assurance testing methodology to test the robustness of the software application.

Detailed explanation-2: -It can be generalized that for n input variables in a module, 7n test cases can be designed with robust worst-case testing.

Detailed explanation-3: -For a program with n-variables, robustness testing will yield (6n + 1) test-cases. Thus we can draw the following Robustness Test Cases graph. Each dot represents a test value at which the program is to be tested. In Robustness testing, we cross the legitimate boundaries of input domain.
