tap-exit-code/test/index.js

Receives streaming TAP, passes it through, and sets the process exit code to 1 if there are any failing tests.

const {spawn} = require('child_process')
const {join: joinPath} = require('path')
const fs = require('fs')

  t.plan(1)

  fs.createReadStream(joinPath(__dirname, 'fixtures/pass.tap'))
    .pipe(p.stdin)
  p.on('close', exitCode => t.equal(exitCode, 0))
