Is it possible to set up travis to run tests for several languages?

Question

I have a rails project and am running tests for my JavaScript test (Jasmine) through Karma

.travis.yml file

language: ruby rvm:   - 2.0.0 script:   - RAILS_ENV=test bundle exec rake --trace db:migrate test   - karma start --single-run --browsers PhantomJS test/karma/config/unit.js 

Travis fails saying it does not find karma. is there a way to define node_js as another language and install karma on the build VM?

Answer 1

It is not possible yet to have several languages on travis configuration file.

On the other hand, all environments run node.js. The following script does the trick:

language: ruby rvm:   - 2.0.0 before_script:   - npm install karma script:   - RAILS_ENV=test bundle exec rake --trace db:migrate test   - karma start --single-run --browsers PhantomJS test/karma/config/unit.js

K-Yo's answer got me moving in the right direction, but far short of success. Here is what I needed:

First in my .travis.yml:

language: ruby  rvm:   - 2.1.1  before_script:   - psql -c 'create database spokenvote_test;' -U postgres   - cp config/database.travis.yml config/database.yml   - rake db:test_prep   - npm install karma   - npm install karma-jasmine   - npm install karma-coverage   - npm install karma-phantomjs-launcher   - npm install karma-coffee-preprocessor  script:   - bundle exec rspec spec # basic for ruby   - node_modules/karma/bin/karma start config/karma.conf.js --single-run --browsers PhantomJS 

Then I also placed this code in my package.json, though I'm not sure if it was needed:

"devDependencies": {     "karma": "~0.12",     "karma-jasmine": "~0.2",     "karma-coverage": "~0.2.6",     "karma-phantomjs-launcher": "~0.1.4",     "karma-coffee-preprocessor": "~0.2.1" }, 

Finally, I learned that Travis is case sensitive, so:

'bower_components/jquery/dist/jquery.min.js', 

in my karma.conf.js needed to be:

'bower_components/jQuery/dist/jquery.min.js',
