Disconnected, because no message in 10000 ms.

Jasmine 2.7.0 fails to launch headless Chrome (--no-sandbox) on Shippable node_js 7.4.0. As a workaround, reverting to 2.6.4 resolves the issue.

Logs copied below, for reference.

$ xvfb-run --server-args="-ac" yarn test

yarn run v0.24.5
$ ng test -cc -sr --progress false --reporters coverage-istanbul,junit,spec

Jasmine doesn't launch a browser, it should be karma that's doing that for you. Check over here: https://github.com/karma-runner/karma

Hope this helps. Thanks for using Jasmine!

Hrmm ... I wonder why changing the Jasmine package version in isolation causes this behavior, but I shall follow up with the Karma team.

Thanks, Gregg!

See angular/angular-cli#7281

Add this to your Karma.conf:

captureTimeout: 210000,
browserDisconnectTolerance: 3, 
browserDisconnectTimeout : 210000,
browserNoActivityTimeout : 210000,

@byrondover I don't think the Karma team will be able to assist you much further on this issue. I was having the same problem and following the advice of @cport1 resolved my issue, but he set his timeout to nearly four minutes. I found that 30 seconds was more than enough time. Might bump it up to 60 seconds. Running this all on Jenkins daily so I'm sure I'll get an email if this happens again. For development I am running off of an older Macbook Pro 13" Mac OS X Sierra.

Thanks, gents! Appreciate the advice. 🙂

Thanks @cport1 - This worked like a charm.

Using @swetapatil1 answer, I am now able to finally work!

Using the flags from this:

/home/jenkins/workspace/node_modules/puppeteer/.local-chromium/linux-579032/chrome-linux/chrome --user-data-dir=/tmp/karma-62557134 --no-default-browser-check --no-first-run --disable-default-apps --disable-popup-blocking --disable-translate --disable-background-timer-throttling --disable-renderer-backgrounding --disable-device-discovery-notifications --disable-gpu --headless --no-sandbox --remote-debugging-port=9222 http://localhost:9876/?id=62557134

You may also want to try the same command but without --headless to see what happens. (Note that the URL will probably be invalid.)

I was finally able to forge a working karma.conf.json (for headless ubuntu+chrome):

karma.conf.json

      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client:{
      clearContext: false, // leave Jasmine Spec Runner output visible in browser
      jasmine: {
        random: false
      }
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, 'coverage'),
      reports: [ 'html', 'lcovonly' ],

    },

};
