test converter, work in progress

[WardCunningham]

The tck is written in the style of Cucumber tests. We explore the possibility of mechanically converting these to the Deno test framework. Our first question, do we understand how we will recognize the various parts of the test specification.

We tally the keywords that begin each line of input. Given, When and Then are expected. A few other keywords appear in some feature files. We add additional match cases until we encounter no more surprises.

A next step would be to look a little deeper into the keyword lines. Then we would define Deno test helpers that match the semantics of those used in Cucumber.
