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
