Which type of test case is mainly generic and conceptual?

High-level test cases are designed to be more generic and conceptual in nature. They provide a broad overview of the testing objectives and goals without delving into the specific implementation details. High-level test cases often focus on overall functionality, user journeys, or major system features and are developed based on understanding the requirements at a higher level.

This approach allows for better alignment with business objectives and stakeholder expectations, ensuring that the testing process addresses the most critical aspects of the software. High-level test cases serve as a foundation for more detailed testing, which can include low-level test cases that provide specific scenarios or conditions.

In contrast, low-level test cases are more detailed and specific to particular functionalities or components, while concrete test cases are similar in that they focus on particular conditions or inputs. Exit test cases are used to determine whether a software release is ready for production, which is a more specific purpose. High-level test cases, therefore, stand out as the most generic and conceptual type of test case among the options provided.
