How to serve JSON files in karma

问题:

I am having great trouble to get Karma to serve json files that are needed in my application. I don't want to mock the json, I just need it to be served on the karma server.

When I check in the Karma browser, I can load the HTML files in the template folder just fine. But the JSON files in the data folder are not found.

But I have configured both folders in the exact same way!

I tried to add the fixture plugin, but it has no effect on JSON files being served.

My Karma configuration:

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: './',

    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: [
        'jasmine-jquery',
        'jasmine',
        'requirejs',
        'fixture'
    ],


    // list of files / patterns to load in the browser
    files: [
        //frontend
        {pattern: 'frontend/js/*.js', watched: true, served: true, included: false},
        {pattern: 'frontend/templates/*.*', watched: true, served: true, included: false},
        {pattern: 'frontend/data/*.json', watched: true, served: true, included: false},

        {pattern: 'test/**/*Spec.js', watched: true, included: false},

        //'test/helpers/jasmine-jquery.js',
        'test/helpers/jasmine-ajax-helper.js',
        'test/test-main.js'
    ],

    proxies: {
        "/templates/": "/base/frontend/templates/",
        "/base/../templates/": "/base/frontend/templates/",
        "/data/": "/base/frontend/data/",
        "/base/../data/": "/base/frontend/data/"
    },

    preprocessors: {
        '**/*.json'       : ['json_fixtures']
    },

    jsonFixturesPreprocessor: {
        variableName: '__json__'
    },

    // web server port
    port: 9876,

    // enable / disable colors in the output (reporters and logs)
    colors: true,

    logLevel: config.LOG_WARN,

    autoWatch: true,

    browsers: [
        'Firefox'
    ],

    singleRun: false,

  });//config.set
};//module.exports

One of my application's requireJS modules loads a JSON files:

define([
    "text!../data/mydata.json"
], function (crowdUI, jsonDATA) {//prerequisites
    'use strict';

    fields = JSON.parse(jsonDATA);

});
