Use case testing is a specification-based test technique that is based on the use cases or scenarios that describe how users interact with the system under test. Use case testing aims to find defects in the process flow or functionality of the system under test by verifying that it behaves as expected according to the use cases or scenarios. Use case testing does not require any knowledge of the data flow or structure of the system under test; it only focuses on what the system does rather than how it does it. Use case testing can be done by professional testers or real users, depending on the level and purpose of testing. Use case testing can also be designed by customers or end users, developers, testers, analysts, or anyone who has access to the use case specifications or user requirements. You can find more information about use case testing in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 4, Section 4.2.

Statement coverage is not a black box technique, because it requires knowledge of the internal structure of the code. Black box techniques are based on the external behavior and specification of the software, without looking at the code. Equivalence partitioning, state transition testing, and boundary value analysis are all examples of black box techniques12

The attributes that best match each level of testing are as follows14:

• Component testing: Stubs and drivers are often used (I), as they simulate the behavior of missing or incomplete components.
• Integration testing: Testing for functional and non-functional characteristics (VI), as integration testing verifies that components interact correctly and meet their specified requirements.
• System testing: The test environment should correspond to the production environment (II), as system testing evaluates the system’s compliance with its specified requirements under realistic conditions.
• Acceptance testing: Testing can be based on use cases (IV), as acceptance testing validates that the system meets the user’s needs and expectations
