请参阅中的代码
我想知道如何添加另一个间谍来窥探$filter(‘date’)返回的方法,以便我可以验证
expect(something,something).toHaveBeenCalledWith('1234','dd-MMM-yyyy');
你应该能够模拟传递给控制器的过滤器,并从这个模拟中返回一个间谍.然后,您可以测试间谍是否正常调用.
原文链接：https://www.f2er.com/angularjs/142149.html例：
describe('MyCtrl',function () {
var filter,innerFilterSpy,http,scope;
beforeEach(inject(function ($rootScope,$controller,$http) {
http = $http;
innerFilterSpy = jasmine.createSpy();
filter = jasmine.createSpy().and.returnValue(innerFilterSpy);
scope = $rootScope.$new();
controller = $controller('MyCtrl',{
'$scope': scope,'$http': http,'$filter': filter
});
}));
it('call $filter("date") and test()',function () {
expect(scope.date).toBe('01-Jan-1970');
expect(http.get).toHaveBeenCalled();
expect(filter).toHaveBeenCalledWith('date');
expect(innerFilterSpy).toHaveBeenCalledWith('1234','dd-MMM-yyyy');
});
});
