How to make travis execute Angular tests on Chrome ("Please set env variable CHROME_BIN")

Question

I'm working on a sample Angular project generated by yeoman.
I am able to run karma tests locally (I set system variable CHROME_BIN to point to chromium binary, but this could have been done in more elegant way. Just a quick work-around.)

However, when attempting to produce a successful build with travis, I get following error:

ERROR [launcher]: Cannot start Chrome     Can not find the binary google-chrome     Please set env variable CHROME_BIN 

I've followed the steps described here (basically using generator-travis-ci)
Then tried to fix it with this - got another error:
/home/travis/build.sh: line 142: ./.travis/scripts/install_chrome.sh: Permission denied

It's a standard angular app created with Yeoman - things should work out of the box, whereas reality is different ...
Has anybody successfully configured it?

---

Software versions I've been using:

user@machine:~/somewhere $ yo -v; grunt --version; bower -v 1.0.4 grunt-cli v0.1.9 grunt v0.4.1 1.2.6 

my Travis job: https://travis-ci.org/vucalur/editor-yeoman-test

Use this solution to get it running using the preinstalled Chromium Version in Travis-CI VM: https://github.com/karma-runner/karma/issues/1144#issuecomment-53633076

.travis.yml

  node_js:   - "0.10"  script: node_modules/karma/bin/karma start test/karma.conf.js --single-run  before_install:   - export CHROME_BIN=chromium-browser   - export DISPLAY=:99.0   - sh -e /etc/init.d/xvfb start 

karma.conf.js

module.exports = function(config) {   var configuration = {      /* ... */      // start these browsers     browsers: ['Chrome', 'ChromeCanary'],      customLaunchers: {       Chrome_travis_ci: {         base: 'Chrome',         flags: ['--no-sandbox']       }     },      /* ... */    };    if(process.env.TRAVIS){     configuration.browsers = ['Chrome_travis_ci'];   }    config.set(configuration); };

I'm afraid to say that you can only run Firefox (because it's already installed in the VM) and PhantomJS (because it's portable and headless).

Add the following into your .travis.yml file to startup Firefox:

before_install:   - "export DISPLAY=:99.0"   - "sh -e /etc/init.d/xvfb start" 

Then you'll just have to enable Firefox as a Karma browser in your configs.
