Discuss ISTQB CTFL-Foundation Exam Topic 4 Question 48

A bank is developing a new service that will be delivered via the web. The user interactions are defined as a set of use cases and the service is designed to be available continuously 24/7. In view of the challenging characteristics of the service the test manager has decided that the code should be thoroughly tested at component level.

Which of the following test types will be required during the development? [K2]

AFunctional testing to test security at the system level, load testing at the system level to ensure the system availability is acceptable, regression testing at all levels, structure based testing at the component level only

BFunctional testing to test the use cases at component level, reliability testing to test availability at the integration level, regression testing at the system testing level only, structure based testing at all levels

CFunctional testing of the use cases at system level, load testing at component level to ensure availability is acceptable, regression testing at the system and acceptance levels only, and structure based testing at the integration level only

DFunctional testing to test security at the acceptance level, load testing at the acceptance test level to ensure availability is acceptable, regression testing at the acceptance level only to ensure late changes are made correctly, and structure based testing at the component level

Suggested Answer: A

For a web-based service designed to be available 24/7, a comprehensive testing approach is necessary to ensure functionality, security, reliability, and performance. Functional testing at the system level will verify the security aspects. Load testing at the system level will ensure the system can handle expected loads and remain available. Regression testing across all levels will confirm that changes do not introduce new defects. Structure-based testing at the component level will ensure the internal structure of components is robust. The ISTQB syllabus outlines these testing types and their importance in different contexts and levels.

I lean towards option D. Acceptance level testing is important for security.

Lamonica 1 month ago

Option C seems off. Load testing should be at the system level, right?

Joanne 2 months ago

I prefer option B. Component level testing is key for use cases.

Lisbeth 2 months ago

I think option A covers everything needed. Security and load testing are crucial.

Carey 2 months ago

Option C seems better for system level testing. More comprehensive.

Francoise 2 months ago

I prefer option B. It focuses on component level testing.

Emerson 2 months ago

But isn't regression testing at all levels too much?

Juan 2 months ago

I think option A covers everything we need.

Mendy 3 months ago

I lean towards option D. Acceptance testing is key for final security checks.

Sommer 3 months ago

Option C seems off. Load testing should be at the system level, right?

Mauricio 3 months ago

I prefer option B. Testing at the component level makes sense for reliability.

Ludivina 3 months ago

I think option A covers all bases. Security is crucial!

Thersa 3 months ago

I agree with A, thorough testing is key for 24/7 services!

Rodolfo 4 months ago

Wait, why is D only focusing on acceptance level? That seems risky.

Berry 5 months ago

C seems off, why load test at the component level?

Marnie 5 months ago

I think B is better for focusing on component level testing.

Pearlie 5 months ago

Sounds like A covers all bases with functional and load testing!

Inocencia 6 months ago

Isn't it risky to rely on just regression testing at the system level?

Renay 6 months ago

I agree with A, it covers all bases for security and availability.

Genevive 6 months ago

Wait, why would you do load testing at the component level? That seems off.

Catarina 6 months ago

I think B makes more sense for component-level testing.

Pete 6 months ago

Sounds like A is the most comprehensive option.

Patti 6 months ago

I vaguely remember that structure-based testing is typically done at the component level, but I’m not clear on how it fits with the other testing types mentioned here.

Desmond 7 months ago

I feel like regression testing is crucial at all levels, but I’m uncertain about whether it should be included in the integration level as well.

Una 7 months ago

I think we practiced a question similar to this where load testing was emphasized for availability, but I can't recall if it was at the component or system level.

Felicidad 7 months ago

I remember we discussed the importance of functional testing for use cases, but I'm not sure if it should be at the component level or system level.
