Mocha测试以及对“ require”模块的后续调用

Question

I have a project that uses Mocha test runner via the commandline ( mocha -- test/test-dir ) and Browserify. Currently the unit tests are very simple and we just require the source javascript (unbrowserified) to run the tests on. So far it has worked fine.

//test/test-dir/my-test.js

var foo = require('../../js/src/foo.js');
var assert = require('assert');

describe('foo.getBar', function() {
...

We recently wanted to add another dependency to foo.js , typeahead.js .

//js/src/foo.js

var jQuery = require("jquery");
var typeahead = require("typeahead.js");

...

Now our simple test fails with a TypeError: _.mixin is not a function . This _.mixin is defined in typeahead.js but I'm suspecting that the nested require in foo.js is not being evaluated by Mocha?

Not too familiar with Mocha or Browserify, I thought that switching the test to use the browserified version of the foo.js would help as then the required modules would be built and available in foo.min.js , although I'm seeing the same error. I know that typeahead supports CommonJS packages so I'm not sure what is wrong with these tests? Any help would be very much appreciated. Thanks!

I added mochify to handle what I believe to be some commonJS issues with Mocha. I'd love to know why this works but the tests pass now using mochify -- test/test-dir/**/*.js now. yay.
