what I think a JavaScript BDD syntax should look like

gistfile1.js

story("do a thing", function() {

  scenario("when I do something under certain conditions", function() {

    given("certain conditions", function() {
      console.log("certain conditions");
    });

    when("I do something", function() {
      console.log("I do something");
    });

    then("pigs should fly", function() {
      console.log("pigs should fly");
    });

    and("some other observation", someOtherObservation);

    function someOtherObservation() {
      console.log("some other observation");
    }

  });

});
