Requirements Based Testing Techniques: Modeling and Use Cases


Course Details


Use cases have proven to be a very powerful technique for gathering detailed requirements. Specifically, Use Cases help derive details on interactions between the system and all types of users and other external entities interacting with it. These details are equally important for the development team and the test team in order to deliver a high quality system. Although many projects have used some form of Use Cases, few projects reap the full benefits of this powerful technique because they do not know how to hierarchically integrate essential business level use cases with detailed, interface specific, concrete use cases and then systematically derive test cases from the use case hierarchy.

The role of use cases in the requirements process is examined, and best practices explored. Use cases are an official part of the Unified Modeling Language (UML) – a specification maintained by the OMG. We will examine the official UML specification of a use case and compare it to actual usage in industry. A use case template is presented and sample use cases critiqued.

Course Objectives:

  • Learn how to effectively participate in Use Case development and analysis sessions
  • Learn how to systematically identify Use Case scenarios to find system requirements otherwise missed that must be handled by the system and tested by the test team
  • Learn how to systematically derive test cases and test procedures from use cases
  • Understand the role of Use Cases in UML and the various industry approaches to Use Cases
  • Learn how to structure use cases to improve clarity and eliminate redundancy

Additional Topics include:

  • Use Cases and UML
  • Actor models
  • Preconditions, post-conditions
  • Success scenarios, failure scenarios, alternate courses
  • Domain analysis
  • Essential use cases, Concrete use cases
  • Actor goals
  • Writing Use Cases
  • Use case template
  • Extends, includes, generalization, uses
  • Use Case to Test Case
  • Test scenarios
  • Use Case Guidelines and Pitfalls
