$httpBackend.whenGET(some url).passThrough() throws exception?

I have some problem here. I am trying to mock some of my http request to the server and pass some of them through ! When I call passThrougth() an Error is thrown !

Error: Unexpected request: GET view/networks.html
No more request expected

here is my run

myAppDev.run(function ($httpBackend) {
    $httpBackend.whenGET("view/networks.html").passThrough();
    $httpBackend.whenGET('/r/networkInterface').respond(networkInterfaces);

});

What is the problem with my config ?

Any way, When I call response(" with some response "), I get results right. i.e the $httpBackEnd returns what is put in response !
