Use Cases Benefits in Software Testing

Use Case

A use case is very important in testing because most of the test cases developed are at the system or acceptance level. Use cases “capture how a user will interact with a solution to achieve a specific goal.” Use Cases will provide as well describe step by step process that a user will go through to achieve the stated objective. They are so important that if written properly, one doesn’t need to be an IT expert to use them when executing the test cases for the desired results.

Elements of a use case

A use case has similar elements as any test case that is used in the software testing. Below are the elements of a use case.

  • Name – It is used to define the scope of the use case
  • Description – Contains the text to describe the scope
  • Preconditions – Anything that can be thought of as being true when the use case begins.
  • Flow – The flow can be basic or alternate or Exception. The flow will capture how the user will interact with the system.
  • Post Conditions – Something that will be true when the use case has been completely executed.

Benefits of Use Case

  • Easy to understand – Use cases since they mainly focus on the user or customer interaction of the system, the software needs are easily communicated back to the developer. A quick fix will be done based on the feedback from the customer or user.
  • Things that may go wrong – More so, use cases help to identify exceptions to perfect scenario by identifying what might go wrong early in the project. More requirements will be required hence saving time before the project is rolled with defects.
