如何使用Jasmine编写angularJS代码的测试用例

Question

我必须为以下代码编写测试用例。有人可以建议如何编写以下代码的测试用例吗？

  $scope.forgotPassword = function (event) {
  var useFullScreen = ($mdMedia('sm') || $mdMedia('xs')) && 
  $scope.customFullscreen;
  $mdDialog.show({
      controller: ForgotPasswordController,
      templateUrl: 'views/forgot_password.html',
      parent: angular.element(document.body),
      targetEvent: event,
      // locals:{tenant_id: $scope.tenant_id},
      fullscreen: useFullScreen
    })
    .then(function(answer) {
      // $scope.getAllTenants(0);
    }, function() {
      $scope.status = 'You cancelled the dialog.';
    });

  $scope.$watch(function() {
    return $mdMedia('xs') || $mdMedia('sm');
  }, function(wantsFullScreen) {
    $scope.customFullscreen = (wantsFullScreen === true);
  });
}
