Butterfly Model of Test Development?

Question

How the 2 wings and body of the Butterfly Model of Test Development is Represented?

Santosh Kumar Kotnala · Answer

Butterfly Model of Test Development: The Butterfly Model focuses on verification and validation of software products. Butterflies are composed of three parts: two wings and body. Each part represents a piece of software testing. The model establishes three general areas of test activities that are illustrated by the butterfly's graphic outline. They are: Test Analysis (butterfly's left wing): The left wing of the butterfly represents test analysis – the investigation, quantization, and/or re-expression of a facet of the software to be tested. Test Design (right wing): The right wing of the butterfly represents the act of designing and implementing the test cases needed to verify the design artifact as replicated in the implementation. Test Execution (butterfly's body): Test execution includes only the formal running of the designed tests. Informal test execution is a normal part of test design, and in fact is also a normal part of software design and development.

Thanks Santosh and Sean for your replies.

The Butterfly Model focuses on verification and validation of software products and is therefore a good fit for software testing tasks that are incorporated into the V-model of software development. This model provides a graphic picture of the complexity of test tasks using the outline of a butterfly. The areas occupied by the wings and body are approximately related to the level of effort afforded to each of the activities included in the model. In addition to this the reference of the butterfly stems from Chaos theory which states that a small disturbance in part of a system can have huge consequences in some other part of the system.
