Understanding the Difference: Test Scenario vs. Test Case

What is Test Scenario?

A test scenario describes how the application functionality will be tested. It is typically derived from the use cases and utilized for end-to-end testing of a feature. Testing that uses scenarios created from use cases is known as scenario testing. Furthermore, by adopting scenario testing, difficult-to-evaluate test scenarios can be used to test sophisticated application logic.

What is Test Case?

A test case is a series of operations carried out on a system to see if it complies with software requirements and operates properly. A test case's objective is to ascertain whether various system features operate as anticipated and to check that the system complies with all applicable standards, recommendations, and user requirements. The act of creating a test case can also aid in identifying flaws or mistakes in the system.

Test Scenario vs Test Case: 

Your duties as a QA engineer most likely involve creating test cases that others can run. This "someone" might be you, another QA expert, or anyone on the team, including developers, if you believe that testing should be everyone's duty. However, as we just stated, test cases are step-by-step instructions. Contrarily, test scenarios are all about strategy and tying the test effort to a commercial justification. Let's go through their basic differences:

1. Scope:

A test case has a narrow scope, concentrating on testing a particular feature, functionality, or behavior of the system.

Test Scenario: A test scenario has a broader scope, covering multiple test cases that are related to a specific test situation or business requirement.

2. Reusability:

A test case is typically designed for a specific feature or functionality & is not easily reusable in different scenarios. A test scenario on the other hand can be reused across multiple test cases, making it more adaptable and flexible for testing different aspects of the system.

3. Dependency:

Test cases are usually independent of each other & can be executed individually. Test scenarios are dependent on the successful execution of multiple test cases to achieve the desired objective.

4. Granularity:

Test cases are more granular, focusing on the specific inputs, actions, & expected outcomes for a particular test condition. While, test scenarios are less granular, providing a broader perspective on the overall flow or sequence of events for a specific testing situation.

5. Core Purpose:

This is the most important point for test scenario vs test case difference. A test case is a detailed set of conditions, steps, and expected outcomes designed to test a specific functionality or feature of a system. It focuses on a specific aspect or behavior of the system under test. On the other hand, a test scenario is a high-level description or outline of a specific test situation or condition that needs to be tested. It encompasses multiple test cases and represents a broader testing objective or situation.

Conclusion:

This article talked about the test scenario vs test case differences and now we can conclude that test cases are created from test scenarios. As a logical result, you'll often have far more test cases than test scenarios. Because of the level of detail required, creating test cases is often more labor-intensive.
