3.Boundary value analysis (BVA) is a technique to test boundary value between valid and invalid partitions in test case design. It is another black box test design technique and it is used to find the errors at boundaries of input domain rather than finding those errors in the center of the input. Consider the input field, where users can enter the number of guests to be registered as visitors with the following restriction as shown in Figure 2 below. Total Number of Guest (s): Enter number of guests *Accepts values between 10 - 50 Figure 2: Register Guests (a) How many sets of valid and invalid values are there in the above scenario. (3 marks) (b) Create the BVA table to show the set of valid and invalid values. (6 marks) (c) Identify the minimum boundary value. (2 marks) (d) Identify the maximum boundary value. (2 marks) (e) Create the required SIX (6) test cases for testing all the valid and invalid values. (12 marks)
