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?
Functional testing is necessary to ensure security at the system level, as security is a critical aspect of banking services that needs to be validated in an environment close to real-world use. Load testing should also be performed at the system level to ensure that the service can handle the expected load under realistic conditions and guarantee acceptable system availability. Regression testing needs to be conducted at all levels to ensure that new changes do not introduce defects in any part of the system. Finally, structure-based testing at the component level ensures each individual component of the service functions correctly before integrating them into the larger system.
