未使用业力 spyOn 调用函数

Question

我的控制器是：

window.map.controller('ScheduleHomeController', ['$scope', '$location', '$route', '$routeParams', 'cache', 'patientCache',
    function($scope, $location, $route, $routeParams, cache, patientCache) {

        cache.set('ui', 'headerMessage', '');

        if(cache.get('patient', 'currentPatient').patientId !== $routeParams.patientId) {
            cache.set('patient', 'currentPatient', patientCache.getPatient(parseInt($routeParams.patientId, 10)));
        }

        switch($route.current.originalPath) {
            case '/patients/:patientId/schedule':
                cache.set('ui', 'schedulePage', 'daily-schedule');
                $scope.showScheduleNavbar = true;
                break;
            default:
                $scope.showScheduleNavbar = false;
                break;
        }
    }
]);

我的测试是：

fdescribe('ScheduleHomeController', function() {
    var scope, cache, $route, patientCache, $routeParams;

    beforeEach(function() {
      module('mapApp');

      return inject(function($injector) {
        var $controller, $rootScope;
        $rootScope = $injector.get('$rootScope');
        $controller = $injector.get('$controller');
        $route = $injector.get('$route');
        cache = $injector.get('cache');
        patientCache = $injector.get('patientCache');
        $routeParams = $injector.get('$routeParams');

        scope = $rootScope.$new()
        $route.current = { originalPath: '/patients/:patientId/schedule' };

        $controller('ScheduleHomeController', {
            $scope: scope,
            cache: cache,
            patientCache: patientCache,
            $route: $route,
            $routeParams: $routeParams
        });

        return scope.$digest();

      });
    });

    it('should set the ui.headerMessage to empty', function() {
        spyOn(cache, 'set');
        expect(cache.set).toHaveBeenCalledWith('ui', 'headerMessage', '');
    });

});

所以我希望调用 cache.set，但我得到的是 Expected spy set to have been called with [ 'ui', 'headerMessage', '' ] but it was never called.

我做错了什么？

您必须在函数执行之前监视 cache.set（在控制器初始化中）。所以把它放在 $contorller 之前：

...
spyOn(cache, 'set');
$controller('ScheduleHomeController', {
...
