Test Case vs Test Scenario

A Test Scenario is a high-level description of a functionality that needs to be tested, while a Test Case is a detailed set of steps, inputs, and expected results used to verify that functionality. Test scenarios define what to test, whereas test cases define how to test.

Test Scenario: High-level testing objective focused on what to test.
Test Case: Detailed testing procedure focused on how to test.
Relationship: Test cases are derived from test scenarios, and test scenarios are derived from requirements (SRS/BRS).

Test Case

A Test Case is a detailed document that specifies the steps, input data, execution conditions, and expected results used to verify whether a particular feature of an application works correctly. It ensures that the software meets the specified requirements.

Defines detailed steps to test a specific functionality.
Includes input values, test conditions, and expected outcomes.
Helps in identifying defects and validating software behavior.

Example: Verify that a registered user can log in using a valid username and password and is successfully redirected to the home page after clicking the login button.

Test Scenario

A Test Scenario is a high-level description of a functionality or feature that needs to be tested. It focuses on what to test in the application without providing detailed steps.

Represents a broad testing objective or functionality.
Focuses on identifying areas of the application to be tested.
Serves as the basis for creating detailed test cases.

Example: Payment Gateway Test Scenario Verify that a user can successfully complete a payment using available payment methods.
