karma-ng-json2js-preprocessor

Preprocessor for converting JSON files to AngularJS constants.

Installation

The easiest way is to keep karma-ng-json2js-preprocessor as a devDependency in your package.json. You can simple do it by:

npm install karma-ng-json2js-preprocessor --save-dev

Configuration

// karma.conf.js
module.exports = function(config) {
  config.set({
    preprocessors: {
      '**/*.html': ['ng-html2js'],
      '**/*.json': ['ng-json2js']
    },

    plugins: [
        'karma-ng-json2js-preprocessor'
    ],

    files: [
      'test/fixture/*.js',
      '*.html'
    ],

    ngJson2JsPreprocessor: {
      // strip this from the file path
      stripPrefix: 'test/fixture/',
      // prepend this to the
      prependPrefix: 'served/',

      /* or define a custom transform function
      cacheIdFromPath: function(filepath) {
        return cacheId;
      }
      */
    }
  });
};

How does it work ?

This preprocessor converts JSON files into Angular constants and puts them in separate Angular modules; each named the same as the source JSON file and generates Angular modules.

For instance this test/fixture/data.json ...

{
    prop: val
}

... with the configuration given above will be converted into:

angular.module('served/data.json', []).constant('servedData', {
    prop: 'val'
});

Inject json fixture into your test case:

describe('me', function(){
    beforeEach(module('served/data.json'));

    it('should not fail', function() {
        var testFixture;
        inject(function (_servedData_) {
            testFixture = _servedData_;
        });

        expect(testFixture).toEqual({
            prop: 'val'
        });
    });

});
