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?

Option D seems the most thorough to me!

I think just going for end-to-end without acceptance testing is risky.

Wait, are we really trusting those vendors' testing? Seems sketchy.

Sounds like a solid plan to include both integration and end-to-end tests!

I’m a bit confused about the re-testing part in option D. Wouldn't that add unnecessary time, or is it really needed to ensure quality?

I think planning for both a system integration test and an end-to-end test makes sense, especially since we know the vendors' testing was poor. It seems like a safer approach.

I’m not entirely sure, but I feel like just doing an end-to-end test without checking the off-the-shelf systems first 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 C sounds like a good balance - system integration testing to verify the integration, plus an end-to-end test to ensure the overall system works as expected. I'll give that some serious thought.
RA

I'm leaning towards option D. Thorough testing of the individual systems, followed by system integration and end-to-end testing, seems like the safest approach given the quality concerns.

Hmm, the question mentions a high likelihood of quality issues with the off-the-shelf systems. I think planning for adequate re-testing of those systems before integration testing is key.

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.

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?
