Description: Scenario testing is a validation technique in the realm of automated testing and software testing, based on executing predefined test cases to evaluate the software’s behavior under specific situations. These tests allow for simulating real-world conditions, ensuring that the software performs as expected under various circumstances. By defining concrete scenarios, development teams can identify errors and unexpected behaviors before the software is released to the market. This methodology is particularly relevant in the context of Test-Driven Development (TDD), where scenarios are used to guide code development, ensuring that each new feature meets established requirements. Scenario testing not only helps improve software quality but also facilitates communication among team members, as it provides a clear and understandable framework for discussing the expected behavior of the system. In summary, scenario testing is an essential tool in any development team’s arsenal, contributing to the creation of more robust and reliable software.
