Encountering the error message "require is not defined" while running tests in AngularJS with Karma

I have implemented AngularJS with Browserify for my app development. To conduct testing, I have decided to utilize Karma. The configuration file I have set up is as follows:

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

    basePath: '',

    frameworks: ['jasmine', 'browserify'],

    files: [
      'node_modules/angular/angular.js',
      'node_modules/angular-mocks/angular-mocks.js',
      'src/app/*',
      'src/app/*/*'
    ],

    exclude: [
      'src/app/*/*.jade'
    ],

    reporters: ['progress'],

    port: 9876,

    colors: true,
    logLevel: config.LOG_INFO,

    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false,

    browserify: {
      debug: true
    },

    preprocessors: {'src/app/*/*.js': ['browserify']}
  });
};

Furthermore, my app.js file is structured as below:

    require('angular')
require('angular-mocks')

var uiRouter          = require('angular-ui-router')
var serices    = require('./services')
var directives  = require('./directives')
var controllers = require('./controllers')
var routes            = require('./routes')

angular.module('myApp', [uiRouter, 'ngMocks'])
  // load Routes
  .config(routes)

  // Services
  .service('someService', services.someService)

  // Controllers
  .controller('myCtrl', controllers.myCtrl)

  // Directives
  .directive('myDirective', directives.myDirective);

Despite using karma-browserify, I encounter an error message during testing:

'require is not defined'

What steps can I take to resolve this issue?

Answer №1

To successfully execute your unit tests, it is necessary to utilize browserify on the test files and ensure they are included in the files list. In this instance, I have incorporated bundled.js, which contains browserified application code.

This method closely aligns with your approach and has proven effective.

(function() {
    'use strict';
    // Configuration for Karma

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

            // Base directory used to resolve patterns such as files and exclusions
            basePath: '../',

            // Frameworks utilized
            // Available frameworks: https://npmjs.org/browse/keyword/karma-adapter
            frameworks: ['mocha', 'chai-as-promised', 'chai', 'browserify'],

            // Files and patterns to load in the browser
            files: [
                // Application-specific code generated by gulp browserify, includes Angular
                'webapp/bundled.js',
                // Third-party resources
                'node_modules/angular-mocks/angular-mocks.js',
                // Test files
                'unit/**/*.js'
            ],
            // Excluded files
            exclude: ['karma.conf.js', 'protractor-conf.js'],
            // Browserify configuration
            browserify: {
                watch: true,
                debug: true
            },
            // Preprocessing of files before serving to the browser
            preprocessors: {
                'unit/**/*.js': ['browserify']
            },

            // Reporter for test results
            reporters: ['progress'],

            // Port for the web server
            port: 9876,

            // Color output in the reports and logs
            colors: true,

            // Logging level
            logLevel: config.LOG_INFO,

            // Watch files for changes and execute tests accordingly
            autoWatch: true,

            // Browsers to launch
            browsers: ['Chrome', 'IE', 'Firefox'],

            // Continuous integration mode
            singleRun: true
        });
    };
})();
