One more thing, user stories arent just single sentence affairs. It will find out the defects in integration testing. Consider a scenario where a user is buying an item from an online shopping site. The use case explains the goal of the technology or process, not how the technology functions. Scenarios help a complex system to test better where in the scenarios are to be credible which are easy to evaluate.
In software and systems engineering, a use case is a list of actions or event steps, typically defining the interactions between a role known in the unified modeling language as an actor and a system, to achieve a goal. Its different than a business process, which might capture all the things that that user would do to achieve a bigger picture goal or outcome in the organization. Use case testing is a functional testing technique which helps in identifying and test scenario on the whole system or doing start to end transactions. Use cases capture all the possible ways the user and system can interact that result in the user achieving the goal. As a tester, you should put yourself in the end users shoes and figure out. What is difference between test cases vs test scenarios. You can use scenarios to expose failures to deliver. A usecase scenario is an instance of a use case, or a complete path through the use case.

In software and systems engineering, a use case is a list of actions or event steps, typically defining the interactions between a role known in the unified modeling. They are described by ivar jacobson in his book objectoriented software engineering. Test scenario, also known as scenario testing, is a highlevel documentation of a use case.
Use case and use case testing complete tutorial software. Hence use case testing is defined as a blackbox test design technique in which test cases are designed to execute scenarios of use cases. In order to understand this in detail, lets look into a familiar use case of login functionality. In this type of testing, the testers take assistance from clients, stakeholders, and developers to create test scenarios that ensure all the business. Use case testing is defined as a software testing technique, that helps identify test cases that cover the entire system, on a transaction by transaction basis from start to the finishing point. Use case testing is a functional testing technique which helps in identifying test scenario on the whole system or doing start to end transactions.
