Certified Associate in Software Testing (CAST) Practice Test

Which method ensures that data is correctly passed from one system to another?

1. Intersystem Testing

2. Control Testing

3. Functional Testing

4. White Box Testing

The correct answer is: Intersystem Testing

Intersystem Testing is a method specifically designed to verify the interactions and data flow between two or more systems. This type of testing assesses whether data is accurately exchanged during integration and focuses on how well systems communicate and interface with each other. During this testing phase, aspects such as data integrity, format conformity, and accurate response generation are thoroughly evaluated. The goal is to ensure that all data passed from one system to another maintains its correctness and usability, which is critical in environments where multiple systems operate in tandem, such as in enterprise software solutions. The other methods listed do not specifically focus on ensuring data transfer accuracy between systems. Control Testing generally pertains to the evaluation of control measures within a system rather than interaction between multiple systems. Functional Testing is broader and assesses whether the application behaves as expected in terms of functionality, but it does not specifically target data hand-off between systems. White Box Testing concentrates on the internal logic of the code and its structural aspects rather than inter-system data communication. Therefore, Intersystem Testing is the most appropriate method for validating the correct passage of data between systems.
