Loading a mock JSON file within Karma+AngularJS test

Question

I have an AngularJS app set up with tests using Karma+Jasmine. I have a function I want to test that takes a large JSON object, converts it to a format that\'s more consumab

Answer 1

Serving JSON via the fixture is the easiest but because of our setup we couldn't do that easily so I wrote an alternative helper function:

Repository

Install

$ bower install karma-read-json --save

  OR

$ npm install karma-read-json --save-dev

  OR

$ yarn add karma-read-json --dev

Usage

1. Put karma-read-json.js in your Karma files. Example:

   files = [
     ...
     'bower_components/karma-read-json/karma-read-json.js',
     ...
   ]
   

2. Make sure your JSON is being served by Karma. Example:

   files = [
     ...
     {pattern: 'json/**/*.json', included: false},
     ...
   ]
   

3. Use the readJSON function in your tests. Example:

   var valid_respond = readJSON('json/foobar.json');
   $httpBackend.whenGET(/.*/).respond(valid_respond);
