Test#registerHelper()

registerHelper is used to register a test helper that will be injected when App.injectTestHelpers is called.

The helper method will always be called with the current Application as the first parameter.

For example:

Ember.Test.registerHelper('boot', function(app) {
  Ember.run(app, app.advanceReadiness);
});

This helper can later be called without arguments because it will be called with app as the first parameter.

App = Ember.Application.create();
App.injectTestHelpers();
boot();
