BCS TM12 Exam - Topic 2 Question 106 Discussion

Actual exam question for BCS's TM12 exam

Question #: 106
Topic #: 2

[All TM12 Questions]

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) system

all 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

AYou 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

BYou 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

CYou should plan for two levels: a system integration test and an end-to-end test of the overall integrated system

DYou 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

An informal acceptance test? That’s risky!

I’d go for option D, we need thorough testing for sure.

I recall that re-testing is crucial when dealing with unreliable vendors. Option D sounds like it covers all bases, but I'm not entirely sure if we need that much re-testing.

I think we practiced a similar question where we had to decide on testing levels. Planning for both system integration and end-to-end tests seems like a safer bet given the risks.

I'm a bit unsure about the best approach here. I feel like just doing an end-to-end test without any acceptance testing might miss some critical issues.

I remember we discussed the importance of thorough testing, especially when integrating low-quality systems. I think we should definitely consider more than just a minimal acceptance test.

Option D sounds like the best choice to me. Doing adequate re-testing of the off-the-shelf systems, followed by system integration and end-to-end testing, should help catch any issues and ensure the overall system works as expected.

I'm leaning towards option C - a system integration test and an end-to-end test of the overall integrated system. That seems like a comprehensive way to test the integration, even if the individual systems may have quality issues.

Hmm, the question mentions a high likelihood of quality issues with the off-the-shelf systems. I think planning for adequate re-testing and then system integration and end-to-end testing is the safest approach.

This seems like a tricky question. I'll need to carefully consider the different testing approaches to mitigate the risk of the low-quality off-the-shelf systems.

I'm picturing the test team right now, chugging coffee and running every possible test scenario. Option D is the only way to go, but I hope they have a good supply of caffeine!

I'm going to have to disagree with option A. 'Informal and minimal' acceptance testing is not going to cut it here. We need to be extra cautious and do it right. Option D is the way to go, no doubt.

Option B sounds tempting, but with the quality concerns, I don't think we can skip the acceptance testing of the off-the-shelf systems. Let's go with option D and be thorough.

I think option D is the best choice here. Given the high likelihood of quality issues with the off-the-shelf systems, we need to plan for adequate re-testing to ensure they are working as expected before integrating them with the core systems.
