ISTQB Exam ATM Topic 2 Question 73 Discussion

Actual exam question for ISTQB's ATM exam

Question #: 73
Topic #: 2

[All ATM 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-theshelf 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?

K4 3 credits

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

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.

Haha, these vendors must think we were born yesterday! Option D is the only way to go. Retesting, integration, the whole nine yards. Can't let a couple of cowboys ruin the show, am I right?

Hmm, I'm leaning towards option C. A system integration test and an end-to-end test should give us a good handle on how everything's working together. Though I do like the sound of that 'adequate retesting' in option D. Gotta make sure those external systems are up to par.

Definitely, option C seems like the most comprehensive approach. We need to make sure everything integrates well before moving forward.

I agree, option C sounds like a solid plan. Testing at both the system integration level and end-to-end level is crucial.

Option D all the way! Retesting those off-the-shelf systems is a must. Can't risk integrating faulty components and having the whole system go haywire. I bet the vendors are just trying to pawn off their junk on us.

Absolutely! It's crucial to ensure the quality of each component before integrating them into the overall system. Option D provides a comprehensive approach to mitigate the risks associated with low-quality off-the-shelf systems.

I think option D is the best choice here. Given the high likelihood of low quality in the off-the-shelf systems, it's crucial to plan for adequate retesting before moving on to the integration and end-to-end tests. It's better to be safe than sorry, you know?
