What is a Test Case?
A test case is a set of conditions, inputs, and actions used to validate whether a specific feature of an application works correctly.
- It defines what to test, how to test, and expected results
- It acts as a blueprint for testing
- It helps ensure the system works in normal, error, and edge conditions
Components of a Test Case
A standard test case includes:
- Test Case ID
- Test Scenario / Name
- Preconditions
- Test Steps
- Test Data
- Expected Result
- Actual Result
- Status (Pass/Fail)
What is a Test Scenario?
A test scenario is a high-level idea of what you want to test in a product or application.
Test Case vs Test Scenario
Test Scenario → What to test (high-level)
Test Case → How to test (detailed steps)
