Williams established a DevOps model based on Gartner's layered testing strategy using CA Technologies tools. Gartner recommends shifting testing left by focusing on business logic testing using mocking, service virtualization, and reusable scripts. This reduces GUI testing and allows teams to get quality products to market more quickly. Williams implemented Agile Requirements Designer to design test cases, Test Data Manager for data virtualization, and AppTest for test automation to achieve continuous integration based on Gartner's strategy.
