Importance of Test cases

 

1. Definition: Scenarios are functional areas/possibilities; cases are specific, executable procedures.
2. Purpose: Scenarios verify end-to-end functionality (high-level); cases verify specific, granular behavior (low-level).
3. Creation: Scenarios are created first, often derived from requirements or user stories. Cases are created based on scenarios.
4. Detail Level: Scenarios are simple and abstract; cases are comprehensive and detailed.
