GM Financial implemented test data management and service virtualization to improve their testing processes. They started with a proof of concept using CA DevTest and added additional integrations and phases over time. This allowed them to generate more test data, increase test coverage by 30%, and validate changes more repeatably. Phasing in the automation helped them understand best practices for long term use and "shift left" processes in software development.

Abstract
Case Study: GM Financial' s Our Automated Testing Journey
The CA engagement at GM Financial built an interface for a future application
allowing development and QA to test 6 months before the interface availability.
The engagement incorporated TDM as a future repository of loan parameters
supplying DevTest and SV necessary values for performance. The engagement also
allows for dynamic loan data generation coupled with virtual services that
guarantees new loan parameters.
This story is how we are using automated testing to ensure development builds
utilizing CA Test Data Manager for data, CA Service Virtualization to supplement 3rd
party inquiries necessary to approve a loan or trigger loan attributes for business
rules validation.

Summary

17. 17 © 2016 CA. ALL RIGHTS RESERVED.@CAWORLD #CAWORLD
Outcome of
Automation
Our team was able to increase
funding loans for testing by
200% allowing for a very
granular response to validate
very specific credit and
collections variables.
Phasing Automation
Phasing in automation helped
our team understand the
importance of Test Data
Management and CA
Virtualization in our
environment and determine
best practices for long-term
use.
Benefits with
Automation
Using TDM and Service
Virtualization with test
automation has allowed GMF
to increase test coverage in
certain areas by as much as
30% by creating repeatable
processes to validate monetary
changes.
Summary
Using TDM and CA Service Virtualization allows for GMF to “shift left” for repeatable
processes in software development
