Uncaught ReferenceError: require is not defined

Question

For a project that I am working on I have been using a hodgepodge of JavaScript libraries. The main logic of my code is broken down into multiple commonjs modules. I use google closure to combine the modules into one output js file which I use within my AngularJS application.

The problem I am having is trying to perform tests with testacular. There error I receive is Uncaught ReferenceError: require is not defined. It is happening because, unlike google closure, testacular doesn't understand commonjs modules. There are a couple work arounds I can do, but I was hoping to make it work without having to restructure my code.

1. I can restucture the modules so that I'm no longer using commonjs. I don't like this because it feels like a step backwards. I want my code to be modular.
2. I can run testacular on the compiled js from google closure. I don't mind doing it this way, but I have not been able to trigger everything to work on file changes. Testacular can re-run itself on file changes, but I haven't seen anyway to make google closure re-compile on changes.
3. Finally, I can enable commonjs module in testacular. Ideally this is the way I want to go, but it may not be the easiest.

Has anyone else run into a similar problem? I'm open for trying different things; I just don't want anything hacky.

javaclassstreamreader.spec.js:

"use strict"

var JavaClassStreamReader = require('../javaclassstreamreader.js').JavaClassStreamReader;

describe('javaclassstreamreader', function() {

  it('reader can be constructed', function() {
    var dataView = {
      byteLength : 0
    };
    //FIXME load dataView

    var reader = new JavaClassStreamReader(dataView);
    expect(reader.dataView).toBe(dataView);
    expect(reader.offset).toBe(0);
    expect(reader.maxOffset).toBe(0);
  });

});

javaclassstreamreader.js:

function JavaClassStreamReader(dataView, initialOffset, maxBytesToRead) {
  this.dataView = dataView;
  this.offset = initialOffset || 0;
  this.maxOffset = this.offset + (maxBytesToRead || this.dataView.byteLength);
}
//... code trucated ...

Answer 1

It seems there is/was an issue with Testacular.

Could you try the following:

• clear npm cache: npm cache clean
• install another version of testacular: npm install -g [email protected]
