A test scenario is a statement that describes the functionality of the application to be tested, and it is used for end-to-end testing of a feature. It is a high-level documentation that describes an end-to-end functionality to be tested. Test scenarios are created to ensure that every functionality a website or app offers is working as expected. They are a collective set of test cases that help the testing team to determine the positive and negative characteristics of the project. Test scenarios can serve as the basis for lower-level test case creation, and a single test scenario can cover one or more test cases. Test scenarios are usually created by reading the requirement documents of the system under test and figuring out possible user actions and objectives. They are critical for studying the end-to-end functioning of the program. Test scenarios can be approved by various stakeholders like business analysts, developers, and customers to ensure the application under test is thoroughly tested. Some advantages of test scenarios include that they help ensure complete test coverage, determine the most important end-to-end transactions or the real use of the software applications, and serve as a quick tool to determine the testing work effort and accordingly create a proposal for the client or organize the workforce.
