Application Testing Services: What Pitfalls May Be Encountered While Using The Use Case Method
As with any other software development method, the application of use case techniques may involve many problems. To avoid some of them, you need not to be in a rush to provide application testing services if you have to do with:
Too many use cases. If you feel completely overwhelmed because you have a plurality of ideas about different use cases swimming around inside your head, you may be unable to write each one at the appropriate level of abstraction. Do not create a separate use case for every possible scenario. It is better to include the normal direction of development, alternative directions and exceptions as scenarios in one use case. As usual, the number of use cases exceeds the number of business requirements and functions; however, there are usually much more functional requirements in a project than use cases. QA testing companies are eager to perform required tests on a particular software app to understand if they meet needs and expectations of their users.
Very complex use cases. For instance, use case can be four-pages long, densely filled with a description of the stages of interaction, built-in logic and branch conditions. Such a document may seem to be very unintelligible. Actually, you are not allowed to control the complexity of business tasks, but you can choose the way they are presented in use cases. You select one successful way to execute a use case, with one combination of the valid and invalid values for different logical decisions and call it the normal direction. Define other successful logical branches as alternative directions and assign exceptions for handling failed branches. There can be a multitude of alternative directions, but, each should be concise and understandable. In order not to complicate this scheme, write the use cases using basic terms for describing the interactions between the system and the user, without specifying details.
Addition of the user interface to use cases. In fact, use cases should describe what users need to perform using the system, rather than how it will look on the screen. Focus on the conceptual interaction of the user and the system and postpone work on the user interface until the design stage. For instance, the correct wording at this stage is “the system provides a choice for its user” and not “the system displays a drop-down list”.
