spyOn could not find an object to spy upon for all()

Question

I'm getting the above error when I want to mock http REST services created using Restangular. Here's my piece of code:

var someParameter = [{ "id": 1, "name": "Length" }]
   spyOn(Restangular, 'one').and.callThrough();
    it('expect company service to be called', function () {     
        httpBackend.expectGET('http://localhost:8283/com/companies', {
            someParameter: someParameter
        }).respond(mockToReturn);
    });

Has anybody encountered the same issue.And any fix ?

Solution

This is how I did it, hope it helps.

var Restangular;
beforeEach(inject(function( _Restangular_) {
    Restangular = _Restangular_;
    spyOn(Restangular, 'all').and.callThrough();
}));

Trying to use inject and it is near impossible to debug because there is no explanation as to what it is or why to use it.

No, spies should be added in a beforeEach

For reference: it is angular.mock.inject.
