Question 139 - CTFL-2018 discussion

Functional 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 are the test types that will be required during the development1. 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. Therefore, the following test types will be required during the development:

Functional testing to test security at the system level: This type of testing verifies that the software product performs its intended functions according to the user requirements and expectations1.Security is one of the functional aspects that needs to be tested at the system level, as it ensures that the software product protects itself from unauthorized access or harm1.

Load testing at the system level to ensure the system availability is acceptable: This type of testing verifies that the software product can handle the expected or peak load of users or transactions without degrading its performance or functionality1.Availability is one of the quality attributes that needs to be tested at the system level, as it measures how well the software product performs its intended functions under specified conditions without interruption or failure1.

Regression testing at all levels: This type of testing verifies that previously tested software still performs correctly after changes or defect corrections1.Regression testing is required at all levels of testing, as changes or defect corrections can introduce new defects or affect existing functionality1.

Structure based testing at the component level only: This type of testing uses the structure or logic of the source code as a test basis to derive test cases and measure test coverage1.Structure based testing is required at the component level only, as the test manager has decided that the code should be thoroughly tested at component level to ensure its quality and reliability1.
