detect when tap output is finished
npm install tap-finisheddetect when tap output is finished
Normally with tap-parser the'results' event fires only after the stream is closed. This module lets you
detect whether a stream seems closed without waiting for the 'end' event.
Given this tap output in tap_output.txt:
``
TAP version 13wait
ok 1 (unnamed assert)
not ok 2 should be equal
---
operator: equal
expected: 5
actual: 4
...
1..2
and given this script that pipes stdin into the finished stream:
js
var finished = require('tap-finished');
var stream = finished(function (results) {
console.dir(results);
});
process.stdin.pipe(stream);
`We'll use
to create a stream that contains the tap output but doesn't end
and then pipe that to the script:`
$ cat tap_output.txt /dev/stdin | node stream.js
{ ok: false,
asserts:
[ { ok: true, number: 1, name: '(unnamed assert)' },
{ ok: false, number: 2, name: 'should be equal' } ],
pass: [ { ok: true, number: 1, name: '(unnamed assert)' } ],
fail: [ { ok: false, number: 2, name: 'should be equal' } ],
errors: [],
plan: { start: 1, end: 2 } }
^C
Even though the
message never came, we still got the parsed results.
Yay!methods
` js
var finished = require('tap-finished')
`var ws = finished(opts={}, cb)
Return a writable stream
that consumes tap input.
cb(results) fires with the results from
tap-parser
when the stream seems finished or when the 'end' event occurs.opts.wait controls how long to wait in milliseconds for more input before
firing the cb if the 'end' event doesn't fire.install
With npm do:
`
npm install tap-finished
