How to mock promise with data from JSON fixture

I'm testing my Angular controller using mock data pulled in from a JSON file. The problem I'm running into is that my controller expects a promise, whereas my mock data is simply a JSON object.

Relevant controller code:

var vm = this;
var playerId = $routeParams.playerId;

playersService.getInfo({
  playerId: playerId
}).$promise.then(function(info) {
  vm.info = info;
});

Relevant test code:

$httpBackend = $injector.get('$httpBackend');
jasmine.getJSONFixtures().fixturesPath = 'base/test/fixtures';

$httpBackend.whenGET('/api/players/5/info').respond(
  getJSONFixture('info.json')
);

I'm trying to work out how to setup my test to work with the controller's promise structure.
