Testing As a Part of Evolutionary Prototyping Life Cycle

Creation of evolutionary prototypes is a structured step-by-step approach for system development, at that each design stage is determined based on the customer’s feedback as well as test results. The prototypes are especially useful when you are having difficulty defining the basic requirements at the initial stage of the project and at the same time have the opportunity to repeatedly communicate with the customer to understand what he expects from the product. At each iteration, both static and dynamic analyses on your program are carried out.

In Evolutionary Model, development begins with the definition of the initial prototype. If the development is conducted using the spiral model, then the initial model can focus on assessing the major risks of the project. In other cases, the initial prototype can be a user interface layout in which users can provide their feedbacks in the context of functionality and convenience, and ease of maintenance of the system. Static testing should be used during development of an initial prototype, in the form of expertise or a collaborative workshop, for example, such as JAR session. QA company would be glad to examine your products as thoroughly as possible for the purpose of catching nasty and annoying defects.

Once the prototype is defined, the development team starts designing, coding and testing the prototype, while the testing team simultaneously develops test plans, creates tests and runs them. This model requires close interaction between the development team and the testing team so that to sufficiently test the prototype before it is demonstrated to the user. If the functionality of the system increases with each iteration, the test team should be able to conduct regression testing at each phase of the life cycle. In other words, it is necessary to run specific tests to make sure that the old functionality is not destroyed or degraded as a result of adding new functionality. Automation can be extremely useful for regression testing. If the number of tests performed manually increases with each development cycle, the labor costs for testing job significantly increase and require more and more time.

After the completion of a sufficiently large number of development cycles before the final product is sent to the customer will need to complete the final system and acceptance tests of the software.
