 I had two motivations behind Tamarin.  The first was to convert the steps behind my cucumber tests from ruby to javascript _(It seems these days that the front-end javascript developers end up maintaining the ruby steps .... and they hate it!)_ and the second was to simplify those steps to only include the actual tests and not all that extra code just to make the tests work consistently.
