A Test Case is defined as a set of actions executed to verify a particular feature or functionality of the software application. A Test Scenario is defined as any functionality that can be tested. It is also called Test Condition. Test scenarios cover a wide range of possibilities.
|Test Scenario||Test Cases|
|Check Login Functionality||Test Case 1: Check results on entering valid User Id & Password Test Case 2: Check results on entering Invalid User ID & Password Test Case 3: Check response when a User ID is Empty & Login Button is pressed And many more.|
Conclusion: Test cases and Test Scenario are the documents used by the testers to ensure that the application meets the customer requirements. These are the most important documents that the testers prepare prior to testing. Even though the core objective of the documents is the same, there is a difference in their representation.
