travis针对不同版本的ember运行我的测试

我有repo，它使用 ember 1.11.0 .

我的bower.json看起来像这样：

{
  "name": "emberx-autosuggest",
  "dependencies": {
    "ember": "1.11.1",
    "ember-cli-shims": "ember-cli/ember-cli-shims#0.0.3",
    "ember-cli-test-loader": "ember-cli-test-loader#0.1.3",
    "ember-data": "1.0.0-beta.16.1",
    "ember-load-initializers": "ember-cli/ember-load-initializers#0.1.4",
    "ember-qunit": "0.3.1",
    "ember-qunit-notifications": "0.0.7",
    "ember-resolver": "~0.1.15",
    "jquery": "^1.11.1",
    "loader.js": "ember-cli/loader.js#3.2.0",
    "qunit": "~1.17.1"
  }
}

我的测试都在本地传递但是当我推送到github时，travis似乎正在运行我对ember 1.10.0,1.11.0和1.12.0-beta.1的测试 .

我只想对1.11.0运行，如何配置travis来做到这一点？

我的travis.yml看起来像这样：

---
language: node_js
node_js:
  - "0.12"

sudo: false

cache:
  directories:
    - node_modules

before_install:
  - "npm config set spin false"
  - "npm install -g npm@^2"

install:
  - npm install -g bower
  - npm install
  - bower install

script:
  - npm test

我的package.json看起来像这样：
