Unit testing if statement based on $state.includes

I am trying to unit test the init function of this controller.I cannot find a way of doing this and keep getting the error

TypeError: 'undefined' is not a function (evaluating '$state.includes('profile.details')')

I have tried mocking the state as a string and using transitionTo, has anyone else found a way of testing includes for states?

var init = function () {
            $scope.global = global;
            $scope.partialViews = {
                personForm: "/app/users/views/details/_personForm.html",
                passwordForm: "/app/users/views/details/_passwordForm.html"
            };

            if (!$state.includes('profile.details') && !$state.includes('profile.organizations')) {
                if (global.activeProfile.defaultOrganizationId) {
                    $state.go("dashboard.notifications", { orgId: global.activeProfile.defaultOrganizationId });
                } else {
                    $state.go("profile.organizations");
                }
            }
        };
