API
var tapOut = require('tap-out');

var t = tapOut(function (output) {

  console.log(output);
});

t.on('assert', function (assert) {

	// Do something
});

process.stdin.pipe(t);

Methods

var t = tapOut(function (err, output) {})

Returns a stream that emits events with various TAP data. Takes a callback which is called when all parsing is done.

Events

t.on('output', function (output) {})

All output after all TAP data is parsed.
Example output
{
  tests: [
    { name: 'is true', number: 1, raw: '# is true', type: 'test' }
  ],
  asserts: [
    { name: 'true value', number: 1, ok: true, raw: 'ok 1 true value', test: 1, type: 'assert' },
    { name: 'true value', number: 2, ok: true, raw: 'ok 2 true value', test: 1, type: 'assert' }
  ],
  results: [],
  versions: [],
  comments: [],
  fail: [],
  pass: [
    { name: 'true value', number: 1, ok: true, raw: 'ok 1 true value', test: 1, type: 'assert' },
    { name: 'true value', number: 2, ok: true, raw: 'ok 2 true value', test: 1, type: 'assert' }
  ],
}

t.on('test', function (test) {})

Parsed test object with details.
  • type - value will always be test
  • name - name of the test
  • raw - the raw output before it was parsed
  • number - the number of the test

{
  type: 'test',
  name: 'is true',
  raw: '# is true',
  number: 1
}

t.on('assert', function (assertion) {})

Parsed assert object details.
  • type - this will always be assert
  • name - the name of the assertion
  • raw - the raw output before it was parsed
  • number - the number of the assertion
  • ok - whether the assertion passed or failed
  • test - the number of the test this assertion belongs to

{
  name: 'true value',
  number: 1,
  ok: true,
  raw: 'ok 1 true value',
  test: 1,
  type: 'assert'
}

t.on('version', function (version) {})

Parsed version data.
  • type - this will always be version
  • raw - the raw output before it was parsed

{
  raw: 'TAP version 13',
  type: 'version'
}

t.on('result', function (result) {})

Parsed test result data for tests, pass, fail.
  • type - this will always be result
  • name - the name of the result
  • raw - the raw output before it was parsed
  • count - the number of tests related to this result

Tests
{
  count: '15',
  name: 'tests',
  raw: '# tests 15',
  type: 'result'
}

Pass
{
  count: '13',
  name: 'pass',
  raw: '# pass  13',
  type: 'result'
}

Fail
{
  count: '2',
  name: 'fail',
  raw: '# fail  2',
  type: 'result'
}

t.on('pass', function (assertion) {})

Parsed assertion that has passed with details. The assertion formate is the same as the assert event.

t.on('fail', function (assertion) {})

Failed assertion that has passed with details. The assertion formate is the same as the assert event.

t.on('comment', function (comment) {})

Generic output like console.log() in your tests.
  • type - this will always be comment
  • raw - the raw output before it was parsed
  • test - the number of the test this comment belongs to

{
  type: 'comment',
