Using multiple versions of dependencies in Karma tests

I'm writing a module for Angular JS and I'd like to ensure that it works with several versions of Angular. Is there a way to tell Karma to run the test suite with several different dependencies (e.g. first all the tests with Angular 1.2.1, then 1.2.2 and so on)?

With the help of another question I used grunt-karma's overrides to reuse my karma config file. So my Gruntfile.js has this:

meta: {
  jsFiles: [
    'app/scripts/**/*.js',
    'test/spec/**/*.js'
  ]
},
karma: {
  options: {
    configFile: 'karma.conf.js',
    singleRun: true
  },
  angular13: {
    files: [{
      src: [
        'test/ref/angular-v1.3.js',
        '<%= meta.jsFiles %>'
      ]}
    ]
  },
  angular14: {
    files: [{
      src: [
        'test/ref/angular-v1.4.js',
        '<%= meta.jsFiles %>'
      ]}
    ]
  }

Note the src: inside files:. Without it you'll get a "Cannot use 'in' operator ..." error and has to do with how Grunt handles files.

I assume you run your test with Grunt, so you can

1) define your grunt different entries for different angular versions

karma: {
  ang11: {
    configFile: './test/karma-ang1.1.conf.js',
    autoWatch: false,
    singleRun: true
  },
  ang12: {
    configFile: './test/karma-ang1.2.conf.js',
    autoWatch: false,
    singleRun: true
  }
}

2) in each file you refers different angular version and the test suits

3) you configure a task to run sequently your karma config files
