Understanding the Difference: Test Scenario vs. Test Case

This article talks about the test scenario vs test case comparison and states their role in SLDC.

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.

It guarantees full test coverage. They would test everything that needs to be tested before the program is released because test scenarios should ideally be approved by business analysts, developers, and potential users (a control group, ideally). It aids in organizing the testing process and estimating the testing effort needed. It may also be used as a client proposal. It supports prioritizing the testing efforts by assisting in the identification of the most important end-to-end user flows.


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 cases, which serve as step-by-step instructions for each system test, are often developed by members of the testing team or the quality assurance team. Once a system feature or group of features has been completed by the development team, the software testing can officially start. 


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.


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. 

No matter how much intensive a job becomes, at WeTest, test cases and test scenarios are made by industry veterans with a commitment to deliver the projects on time. Their tools like the PerfSight delivers a deep ability to spot game performance problems and optimize player experience. Clients get to improve key performance indicators with this tool and also comes with support for mobile and console platforms.
