Which of the following testing methods verifies the interfaces between components against a software design?

Regression testing is performed to ensure that new code, changes, or bug fixes have not adversely affected existing functionalities of the software.

Integration testing focuses on validating the interfaces and interactions between two or more integrated software modules to ensure they function together correctly as specified by the software design. Its primary goal is to expose defects in the interfaces and interactions between integrated units.

Black-box testing, also known as functional testing, examines the functionality of an application without peering into its internal structures or workings.

Unit testing focuses on verifying the smallest testable parts of an application, such as individual functions or methods, in isolation from other components.
