Cucumber is primarily used for behavior-driven development (BDD) because it allows developers to write test cases in a natural, human-readable language that can be understood by non-technical stakeholders. This aligns with the principles of BDD, which emphasizes collaboration between developers, testers, and business analysts.

Cucumber uses a Gherkin-based syntax to define test scenarios, enabling teams to create a shared understanding of the system's behavior through features and scenarios that describe the desired functionality. This helps ensure that the development process remains aligned with business objectives, as user stories can be directly translated into executable specifications.

The other frameworks mentioned serve different purposes. JUnit and TestNG are primarily testing frameworks for unit and integration testing but do not provide the same level of expressiveness for behavior-driven specifications. Mockito is a mocking framework used in unit testing to create mock objects, but it also does not align with the principles of behavior-driven development in the way Cucumber does.
