tap usage

=== TEST SETUPS ===
t.plan(x) // Expect x asserts. If less, test will timeout, if more, test fails
t.end() // End test if not t.plan() is used
t.fail('fail test with this description')
t.bailout("en test right here. No more to run")

// t.bailsOut() wraps a child test and succeeds if it calls bailout()
  t.bailsOut(t.test("this should bailout", function (t) {
    t.bailout("oh noes, bailing out!")
  }))


=== ASSERTS ===

t.assert = t.true = t.ok = function (trueEval, mess)
t.notOk = t.false function (falseEval, mess)
t.equal = t.equals = t.isEqual = t.is = t.strictEqual = t.strictEquals = function (actual, expected, mess)


t.error = function(err, mess)
t.pass =  function(mess)
t.fail =  function(mess)
t.skip =  function(mess)
t.throws(fn, wanted, mess)
t.doesNotThrow(fn, mess)
