Test Scenario:
- Test scenarios are the generalized statements describing all the major functions in a module.
- A scenario does not go deeply into a function but it just mentions the function name, its purpose and any major filed restrictions through simple English statements.
- Only one major function is covered in a scenario.
- Creating scenarios is like splitting the module into a several sub-modules.
Test Case:
- Test case is a simple English statement that checks a small feature of a scenario or a module.
- It would contain steps explaining how to test the feature.
- Test cases are useful because they are repeatable, reproducible under same environment and easy to improve upon feedback.

Test Data:
- When a test case needs to be checked with various combinations of inputs, instead of randomly giving input while executing the test case, test engineers prepare test data.
- It contains all the possible combinations of inputs
- While writing the test cases itself test engineers prepare test data.
