The Challenge

The customer had an application that used a web-based interface to allow agents, customers, and lenders to access their policy information. It was linked to the customer’s data residing on a mainframe computer. The application had to be released on time, and it was critically important that test coverage was known to eliminate defects in all stages of the end-to-end operation.

There were challenges during the initial period of the project. One involved understanding the complex functionalities of the integrated products in the suite. A second challenge was that 85% of the project was on a company mainframe and testing was done manually. Fast, comprehensive testing was imperative to meet their schedule and avoid surprise errors at the later delivery stages. This was especially true for the mainframe code interaction with the graphical user interface (GUI) application.

The Solution

Manual test design was recognized as a bottleneck that had to be eliminated to enable successful on-time delivery. The client’s manual testing was the baseline used to assess efficiency gain delivered by tools being considered in the deployment. A testing group with insurance representatives and developers made up the team building the applications to ensure that the correct data was accessed. The testing team tried several test suites to find one that satisfied the client’s requirements. First and foremost, it needed to use its current automation platform to handle the application’s complexity, provide known coverage of the system’s operation, run both GUI and mainframe testing, and automatically generate executable scripts to shorten testing time.
