Trouble testing state transition in ui-router

I'm trying to write a test for an Angular app using ui-router similar to that suggested by http://ift.tt/1Dr7N0u.

it('should transition to state', inject(function($rootScope, $state, $log) {
  $rootScope.$on('$stateChangeError', function(ev, toState, toParams, fromState, fromParams, error) {
    $log.error('$stateChangeError: ', error);
  });
  $rootScope.$on('$stateNotFound', function(ev, toState, toParams, fromState, fromParams, error) {
    $log.error('$stateNotFound: ', error);
  });

  var caseId = 1;
  $state.go('case.summary', { id: caseId }, { notify: true, reload: true });
  $rootScope.$digest();
  $log.debug('$state.current.name: ' + $state.current.name);
  expect($state.current.name).toEqual('case.summary');  // fails
  expect($state.is('case.summary', { id: caseId })).toBeTruthy(); // fails
}));

But this test fails.

summary section ✓ should respond to URL LOG LOG: 'debug: caseSvc.get, url: ,http://ift.tt/1Dr7KC4' LOG LOG: 'debug: $state.current.name: ' ✗ should transition to state Expected '' to equal 'case.summary'.

Nevertheless, this test succeeds:

it('should respond to URL', inject(function($state) {
  expect($state.href('case.summary', { id: 1 })).toEqual('#/cases/1/summary');
}));

Currently trying to trace this in the Chrome debugger.

I'm pretty stumped at this point.
