      You inspired me to do that today:
      http://github. com/Walfisch/ boring-assert/

      A Javascript test framework that uses chaining,
      the code to use looks like that then (without with and without "o."):

      assert(!!document. body, "document.body should exist").

      print(!!document. body, "document.body should exist").
      print(!document. body, "document.body shall not exist");

      suite("Suite 1", function () {
      assert.print( typeof alert === "function", "alert is function");
      suite("Suite 2", function () {
      print(0.1 + 0.2 === 0.3, "0.1 + 0.2 === 0.3").
      print(0.5 - 0.2 === 0.3, "0.5 - 0.2 === 0.3");

      > Adding a bunch of "o."s in there bugs ... but that's personal and I'm not trying to convince anyone of that. Most test frameworks just bash the global scope, which I don't like either. I could var up all the functions at the top of the closure, so the ugliness is just in one place, but there are too many functions to duplicate all that code.
