Wedding Cake Model - Functional Testing |
| |
| Abstract |
Insurance companies spend millions of dollars to integrate legacy systems or implement
Straight Through Processing (STP) applications. The success of these integration or
implementation efforts lies in the timely roll out of these applications in accordance with
their business requirements. These systems must be tested thoroughly to verify that
business requirements have been met and that business processes are functioning
correctly and reliably.
Functional testing plays a major role in the release of any new application. New
applications must be thoroughly tested before they can be rolled out. Having a proper
Functional Test Plan helps to mitigate this risk. There are different testing models, tools
and methodologies available in the market to facilitate an effective and efficient functional
test process. Selecting the right process and methodology for your functional testing
ultimately affects the success of the project.
One model for testing new insurance applications is the "Wedding Cake Model". With the
Wedding Cake Model, testing of the application functionality is spread over the testing
phase. The model is designed to gradually increase the complexity of the test case and
functionalities covered over the testing phase. For example, in testing a new business life
insurance application, this model might have a simple case to flow through the system at
the beginning, which is then modified to reflect complex scenarios as the testing
progresses. As the case gets complex, the testing covers more functional areas of the
system.
This paper presents a brief overview of the Wedding Cake Model functional testing
approach, and is designed to help you to structure and plan your testing approach. This
paper also discusses the automation of functional testing to help companies meet tight
delivery schedules.
