Test Case Vs. Test Scenarios
In this section, we are going to discuss the difference between the Test Case and Test Scenario as we understood that both the test case and test scenario are part of Testing documentation.
As test engineers, we must be aware of these two testing terms as they play a major role in the Software Test Life Cycle’s Test Design and Test Execution phases.
But before we see the difference between Test Case and Test Scenarios, first, we will understand the definitions of Test Case and Test Scenario.
What is a Test Case?
The test case is an in-details document that includes all possible inputs such as positive and negative, and the navigation steps. These are implemented during the testing process to check whether the software application is performing the task for that it was developed or not.
What is Test Scenarios?
It is a detailed document of test cases that cover end to end functionality of a software application in liner statements. The test scenario is a high-level classification of testable requirements. Before performing the test scenario, the test engineer needs to consider the test cases for each scenario.
Difference between Test case and Test Scenarios
In the below table, we have listed some of the important difference between test case and test scenarios:
| S.NO | Test Case | Test Scenarios |
|---|---|---|
| 1. | The test case is a detailed document, which provides information about the testing strategy, testing process, preconditions, and expected output. | The test scenarios are those derived from the use case and give the one-line information about what to test. |
| 2. | It includes all the positive and negative inputs, navigation steps, Expected results, pre and post condition, etc. | Test scenarios are one-liner statement, but it is connected with several test cases. |
| 3. | These are low-level actions. | These are high-level actions. |
| 4. | The main objective of writing the test case is to verify the test scenario by implementing steps. | Writing the test scenario’s main objective is a cover end to end functionality of a software application. |
| 5. | It takes more time as compared to test scenarios. | It takes less time as compared to test cases. |
| 6. | The test cases are hard to maintain. | Test scenarios are easy to maintain due to their high-level design. |
| 7. | The test case will help our in-depth testing of the application. | The test scenario will help us in an agile way of testing throughout the functionality. |
| 8. | The test case is work on the basics of “How to be tested”. | The test scenarios are work on the basic to “What to be tested”. |
| 9. | To write the test, we need additional resources to create and perform test cases. | Fewer resources are sufficient to write test scenarios as compared to the test cases. |
| 10. | In a test case, we mainly focus on the document details. | In test scenarios, we will focus on thinking and discussing details. |
| 11. | It can obtain from test scenarios. | It can obtain from the use cases. |
| 12. | If the test engineer is working offside, then the creation of test cases is significant. | If the tester is particularly working in Agile methodology, then creating test scenarios helps us in a time-sensitive situation. |
| 13. | Writing test cases is a one-time attempt that can be used in the future at the time of regression testing. | The test scenarios are a time saving process; that’s why it is preferred by the new generation of software testing community. |
Conclusion
In this section, we have understood the essential differences and impotence of both test case and test scenarios.
Using both the test case and test scenario together ensures robustness and high coverage testing creativity.
It’s the best exercise if we write Test Scenarios first and then write the Test Cases because most IT companies prefer Test Scenarios in today’s Agile time. In the agile era, the test case is being replaced with test scenarios to save time.
