Final Answer

Thank you for the opportunity to help you with your question!

(Meyer,1997)," Object Oriented Software Construction",1997 discusses issues such as driving the system design too literally from use cases and using use cases to the exclusion of other potentially valuable requirements analysis techniques.

  • In some organizations Use cases have been used to design test cases. But use case pre- and post conditions should be applied to all scenarios of a use case which limits the oppurtunity for designing the test cases. For example, the outputs and final state of a failed attempt to withdraw cash from an ATM are not the same as a successful withdrawal: if the post conditions reflect this, they too will differ; if the post conditions donot reflect this, then they canot be used to specify the expected behavior of tests.
  • Some systems like data-mining and Business Intelligence systems are better suited and described in a data driven approach than in a the functionality-driven approach of use cases.

  • Please let me know if you need any clarification. I'm always happy to answer your questions.
