Final answer:
Scenario-based testing focuses on actor and software interaction, helping uncover issues related to usability, functionality, and system performance. However, it may miss errors in specifications or subsystem interactions.
Step-by-step explanation:
Scenario-based testing is a software testing technique that focuses on actor and software interaction. It is used to identify errors in the interaction between the actors (users, systems, etc.) and the software being tested. This type of testing helps uncover issues related to usability, functionality, and system performance.
For example, imagine a scenario where a user interacts with a web application by submitting a form. Scenario-based testing would involve creating test cases that simulate this interaction and verifying if the system responds correctly to the input. This approach is valuable in detecting errors at the user interface level.
Since scenario-based testing conducts tests based on interactions, it may miss errors in specifications or subsystem interactions. It is important to complement this type of testing with other techniques such as boundary testing and requirement-based testing to achieve comprehensive test coverage.
