ReferenceError: Can't find variable: require a

问题:

I have a question about using jasmine with Grunt. I keep getting an error,

ReferenceError: Can't find variable: require at

whenever I run my jasmine tests. Here is my jasmine entry for my Gruntfile.js :

jasmine: {
      js: {
        src: jsFiles,
        options: {
          specs: 'tests/*_spec.js',
          helpers: 'tests/helpers/*',
          vendor: 'vendor/*'
        }
      }
    },

I can run a dummy test without a require just fine, but when I include a require in a test, like so, I get the require error.

var testD = require('../src/events_to_actions');

describe("events_to_actions", function() {
  it("is dummy test", function() {
    expect(true).toEqual(true);
  });
});

I had the same problem. Just install this node package and add this line to your Gruntfile and require should start working again.

https://github.com/cloudchen/grunt-template-jasmine-requirejs

jasmine: {
      js: {
        src: jsFiles,
        options: {
          specs: 'tests/*_spec.js',
          helpers: 'tests/helpers/*',
          vendor: 'vendor/*',
          template: require('grunt-template-jasmine-requirejs')
        }
      }
    },

The solution that @user3741597 is suggesting might work, but it is a bit of a backwards solution.

"grunt-template-jasmine-requirejs" was written for RequireJS, which is an AMD loader. On the other hand, you are using CommonJS syntax. If you want to continue to use "grunt-contrib-jasmine", then you need to find a CommonJS template, or else use the information that Jasmine has node support built-in and take a different approach.

This post may help as well.

Leading on from the solution by @justin-helmer, there is a template that allows you to use require calls (CommonJS syntax) with grunt-contrib-jasmine:

https://www.npmjs.com/package/grunt-template-jasmine-nml

An example of grunt config using this:

jasmine: {
    options: {
        template: require('grunt-template-jasmine-nml'),
        helpers: 'spec/helpers/**/*.js',
        specs: 'spec/**/*.spec.js'
    }
}
