make-tap-output

build status

This is a simple toolkit for making TAP-compatible output.

Usage

make-tap-output exports a single function, and returns a readable stream with handy methods for generating TAP data from that stream.

It takes in an optional opts object. Currently there's only one possible option, which is count. Setting this to a boolean enables or disables the count number in each test result. The default is true.

var tap = require('make-tap-output')({count: true})
 
tap.pipe(process.stdout)

Upon construction, it will immediately emit

TAP version 13

on the stream.

It has these functions:

#plan(num)

tap.plan(13)
// 1..13

#diag(text)

tap.diag('this is a "diagnostic" message')
// # this is a diagnostic message

#yaml(data)

tap.yaml({
  some: {
    data: {
      foo: 'bar'
    }
  },
  stuff: 1
})
//  ---
//  some:
//    data:
//      foo: bar
//  stuff: 1
//
//  ...

#result({ok, message, directive, dataObj})

tap.result({
  ok: false,
  message: 'some failing test',
  directive: 'extra info',
  dataObj: {some: {data: true}}
})
// not ok 1 some failing test # extra info
//   ---
//   some:
//     data: true
//   ...

#pass([message, [directive]])

tap.pass('foo test', 'bar')
// ok 1 foo test # bar

#fail([message, [directive, [err]]])

tap.fail('foo test', 'bar', new Error('foo fail'))
// not ok 1 foo test # bar
//   ---
//   name: Error
//   message: foo fail
//   stack: |-
//     Error: foo fail
//         <stack line 1>
//         <stack line 2>
//         <stack line 3>
//   ...

#bail([message])

tap.bail()
// Bail out!
tap.bail('This is a bail out reason')
// Bail out! This is a bail out reason

#unbufferedSub(name)

var mySub = tap.unbufferedSub('my sub') // This is a new tap instance for you
mySub.test('foo test')
// # Subtest: my sub
//     ok 1 foo test

Note: This does not "end" the subtest. For that, just use pass or fail above.

#bufferedSub(result)

var mySub = tap.bufferedSub({ ok: true, message: 'my sub' })
mySub.test('foo test')
mySub.end()
// ok 1 my sub {
//     ok 1 foo test
// }

Standard?

This module, while helping to produce standard TAP version 13 output, can also produce non-standard output, depending on how you interat with it. For example, if you call plan midway through your tests, that's invalid TAP. It's up to you the user of this module, to use it correctly.
