Difference between test case and test scenario?

A test scenario is a high-level description of a specific testing objective or goal. It outlines the features or functionality that will be tested and the conditions under which the testing will take place. Test scenarios are typically broader in scope than test cases and can encompass multiple test cases.

A test case, on the other hand, is a detailed description of how to test a specific feature or functionality of a system. It includes steps to be taken, expected results, and any preconditions or assumptions required for testing. Test cases are more granular in nature and focus on specific aspects of the system being tested.

In summary, a test scenario is a high-level description of a testing objective, while a test case is a more detailed description of how to test a specific feature or functionality of the system. Test scenarios can encompass multiple test cases, which are more focused on specific aspects of the system.
