How can I see the output of my travis build

My tests (only one) is defined in the package.json file:

  "scripts": {
    "test": "grunt --verbose"
  },

And all I do in the .travis.yml file is:

language: node_js
node_js:
  - "0.10"

script:
  - cd microservicebus.host && npm test

script:
  - echo 'Hello'

Checking connectivity... done.
$ cd microServiceBus/microservicebus.host
$ git checkout -qf 9ad3d17e94e6f4bacbc.....
This job is running on container-based infrastructure, which does not al....
If you require sudo, add 'sudo: required' to your .travis.yml

$ nvm install 0.10
