Boundary value testing question Use the boundary value analysis method to derive a set of black box test cases for the following function that covers all the boundary value analysis criteria. Provide all input data and expected output data. -------- Z = | X Y + 10 when 10 < x <= 15 and 15 <= y <= 25 | X + Y 5 when 0 < x <= 10 and 0 < y < 15 | Undefined when x = -5 and y = 0 | 0 Otherwise -------- a) Define all boundaries. b) Define the boundary values for each boundary. c) Define the test cases for each boundary.
