Designing Reusable Test Automation

This paper introduces the Sequencer design that facilitates the creation and execution of reusable operations. The idea behind the Sequencer is to carve the product under test into sets of functional operations. A test case data file describes the operations to be executed including their order and required data. The Sequencer’s test driver executes the test by loading the test case and sequencing the operations. The beauty of this approach is with a well-stocked library of operations coded, new tests can be generated by combining different sequences of existing operations.
