ttt

A very very small tap-emitting test framework.

This is not a test runner, but you can use tap as your test runner. Because ttt outputs TAP formatted results, it'll get interpreted nicely.

I forked it to make a temporary test runner for Tessel because Tessel has a bug with string formatters and no support for captureStackTrace (yet). Once those two bugs are fixed, we can use izs' default tt lib.

USAGE

Do this in your test script:

var test = require('ttt')

test('first test', function(t) {
  t.equal(2, 1 + 1, 'math works')
  t.equal(0.3, 0.1 + 0.1 + 0.1, 'except when it doesnt')
  t.test('child test', function(t) {
    t.pass('this will always pass')
    t.fail('this will never pass')
    t.end()
  })
  t.end()
})

test('second test', function(t) {
  t.ok(true, 'etc')
  t.end()
})

Run it with node my-test.js, or your favorite TAP-aware test runner thingie.

API

The function exported by require('ttt') is the test function. Give it a name and a function. That function will get an argument object which has some assertion methods.

Every function from require('assert') are supported, but they output TAP data rather than throwing.

Also, you have t.pass(message), t.fail(message), t.comment(message), and t.test(name, fn).
