Testem finished with non-zero exit code. Tests failed.

testem.js: /*jshint node:true*/ module.exports = { "framework": "qunit", "test_page": "tests/index.html?hidepassed", "disable_watching": true, "launch_in_ci": [ "Chrome" ], "launch_in_dev": [ "PhantomJS", "Chrome" ] };

installed Versions: MacOS Sierra 10.12.6 node: 6.12.2 npm: 5.6.0 ember: 2.12.0 ember-cli: 2.18.2 phantomjs: 2.1.1

Below is partial of my tests/index.html file:

<script src="testem.js" integrity=""></script>

<script src="assets/test-support.js"></script>
<script src="assets/myApp.js"></script>

also tried with ember test --server but same error. So anyone has any idea on how to narrow down this and why testem is not getting loaded ?

Answer 1

If you already checked for the obvious browser settings and it still doesn't work: see if you're setting EMBER_ENV=test.

Answer 2

Changed testem.js with below settings. and its working fine :)

/* eslint-env node */
module.exports = {
  test_page: 'tests/index.html?hidepassed',
  disable_watching: true,
  launch_in_ci: [
    'Chrome'
  ],
  launch_in_dev: [
    'Chrome'
  ],
  browser_args: {
    Chrome: {
      mode: 'ci',
      args: [
        '--disable-gpu',
        '--headless',
        '--remote-debugging-port=0',
        '--window-size=1440,900'
      ]
    }
  }
};

Answer 3

For tests usually you need to run chrome in headless mode with enabled remote debugging. Adding these lines to your testem.json should help:

"browser_args": {
  "Chrome": [
    '--headless',
    '--disable-gpu',
    '--remote-debugging-port=9222',
    '--window-size=1440,900',
  ]
}

I also suggest to remove "PhantomJS" line - phantom may not work with recent ember versions due to this issue.
