Design the test cases and test the program of Previous Date problem by using Robustness Testing

In previous date problem, we will test our code using Robustness Testing to check whether it can provide expected the previous date as an output or not. We are considering interval [2000,2050]  for year, [1,31] days for date, [1,12] for month. If we look closely, we require to figure out for given year input whether it is a leap year or not.

We will be using Robustness Testing to generate test cases.  The expected output can be  [Invalid input, Invalid date, previous Date].

Program

Here is the “previous date problem” program along with its tested test cases.

Robustness Testing

So, there will be 6N+ 1 test cases that is 6*3 +1 =19 in this case as we are using Robustness Testing.
