Testing Process -Consider an information system of a Pay-Tv company based on a SOA architecture.The integrated system currently consists of three core systems:- a CRM (Customer Relationship Management) system- a BRM (Billing and Revenue Management) system- a CAS (Conditional Access System) systemall of them communicating with SOA Middleware.You have been asked to manage the testing activities for the integration of two additional off-the-shelf systems from two different vendors: a SMS (Short Message Service) server and an IVR (Interactive Voice Response) system.Assume that there is a high likelihood that the two off-the-shelf systems will be low-quality and that you have a clear proof that the testing performed by the two vendors on their systems has been unsystematic and unprofessional. This obviously leads to higher quality risk for the overall integrated system.You are the Test Manager of this project. Your main goal is to plan for testing activities to mitigate this risk.Which of the following answers best describes the test activities (assuming it is possible to perform all of them) you should plan for?Number of correct responses: 1 -K4 3 credits -

A. You should plan for an informal and minimal acceptance test of the two off-the-shelf systems and then a single end-to-end test of the overall integrated system
B. You should directly plan for a single end-to-end test focused on end-to-end tests of the overall integrated system without an acceptance test of the two off-the-shelf systems
C. You should plan for two levels: a system integration test and an end-to-end test of the overall integrated system
D. You should plan for adequate re-testing of both the systems followed by a system integration test and an end-to-end test of the overall integrated system
