A successful test object with two assertions:

var TapOut = require('tapout')
var tap = new TapOut()

tap.pipe(process.stdout)

tap.write({
  name: 'my first test'
  , results: [
    { name: 'assert was correct', ok: true }
    , { name: 'assert was true', ok: true }
  ]
})

tap.end()

output:

$ node my-test.js
TAP version 13
# my first test
ok 1 assert was correct
ok 2 assert was true

1..2
# tests 2
# pass  2

# ok

var TapOut = require('tapout')
var tap = new TapOut()
tap.pipe(process.stdout)

tap.end({
  name: 'my only failing test'
  , results: [
    {
      name: 'assert was correct'
      , ok: false
      , error: new Error()
      , file: 'my-file.js'
      , line: 20
      , column: 10
    }
  ]
})

$ node my-failing-test.js
