You are implementing test automation for a project and you want to be able to generate test cases automatically using a series of test design tools which use a variety of test design techniques such as decision tables, pairwise testing and boundary value analysis. You also want to generate test data automatically which can then be used by the tests. Initially these tests will be run manually to verify their correctness and ultimately you want to include them in the test execution tool so that they can run unattended. Which layer of the gTAA will be used to support the specification of the test cases and preparation of the test data?
