Can't run tests because of "Uncaught Error: Mismatched anonymous define() module"

[Reinmar]

On 21b0cf9 and ckeditor/ckeditor5-core@237ba98 when running tests I get:

require.js:166 Uncaught Error: Mismatched anonymous define() module: function () {
      return (root.sinon = factory());
    }
http://requirejs.org/docs/errors.html#mismatch
bender.js:105 Error: Deferment unlock timeout - please check your plugins
    at client.js:433

Do I miss something?

That's because of this:
benderjs/benderjs-sinon#5

You should update package.json with the proper version and run npm install there.
