### Allow users to create automated testing suite BDT WEB APP

As a user I would like to be able to save combinations of inputs and their expected outputs as an automated test so that I can automatically execute a suite of regression tests that will ensure my screener is behaving as expected as I make changes. Providing the ability to create automated tests will allow users to increase the reliability of their screeners and avoid bugs as DMN models grow in complexity.

Current Plan
- Allow users to save a current set of inputs and outputs from the preview screen
- Create button to execute all saved tests
- Create screen to view test results including the inputs, expected outputs, and actual outputs of any failing tests.
- Create screen to view currently saved test suites, delete any tests that are no longer needed.
