rimary goals of test automation should be increased coverage, decreased manual effort and flexibility to accommodate changing requirements.  DataDynamo is a new testing tool that supports these goals. This tool supports requirements specification and test case specification in terms of work  flows and data equivalence classes. By using templated output, the format of the test data produced is highly customizable, and can even include  dynamically calculated test expectations. The combined use of straightforward specification inputs, tool-assured test case coverage, and  customizable output enables a tester to achieve increased coverage in less time, while maintaining the flexibility to adapt to requirements changes;  Modifications to the specification input and possibly output templates are all that’s required and the tests are re-generated. This reduces time spent  on test case generation and requirements gathering and alleviates gaps between requirements and test cases generated.
