Review: smashtest.io - test shorthand tree and test case generation

smashtest.io put forward a tree-based shorthand for test case definition.  In a positive direction, the shorthand allows for test definition in an easy to read format that can expand to multiple manual tests and a more detailed test case description or language.  In the negative category, the standard format does not utilize data-driven variables in the language and does not address a strategy or logic for why test cases are selected.  So overall, I can not give a recommendation for this tool over a standard test generator in a spreadsheet but it may work for your organization to move the needle in test definition and generation.
