Testing asynchrone function gives unexpected request

Question

Unittest:

"use strict";

var usersJSON = {};

describe("mainT", function () {


 var ctrl, scope, httpBackend, locationMock, 

    beforeEach(module("testK"));
    beforeEach(inject(function ($controller, $rootScope, $httpBackend, $location, $injector) {
        scope = $rootScope.$new();
        httpBackend = $httpBackend;
        locationMock = $location;

        var lUrl = "../solr/users/select?indent=true&wt=json",
        lRequestHandler = httpBackend.expect("GET", lUrl);          
        lRequestHandler.respond(200, usersJSON);     

        ctrl = $controller("mainT.controller.users", { $scope: scope, $location: locationMock});
        httpBackend.flush();
        expect(scope.users).toBeDefined();

    }));

    afterEach(function () {
        httpBackend.verifyNoOutstandingRequest();
        httpBackend.verifyNoOutstandingExpectation();
    });




        describe("method test", function () {
        it('should test', function () {
            expect(true).toBeFalsy();
        });
    });
});

I test (works): Asynchrone function in init which gives me problems (uses ../ solr / users / select? Indent = true & wt = json):

 $scope.search = function () {
                    var lStart = 0,
                        lLimit = privates.page * privates.limit;


                    Search.get({
                        collection: "users",
                        start: lStart,
                        rows: lLimit)
                    }, function(records){
                        $scope.users= records.response.docs;
                    });
                };

What I think:
1. Tell the backend what request it will receive. 2. inform the backend about the answer to this request with an empty JSON
3. create a controller (Search.get get executed)
4. Inform the backend to receive all requests and respond to them (flash)

But I always get the following error:

Error: Unexpected request: GET : ../solr/users/select?indent=true&wt=json

Have I really missed the asynchronous image search function? how should this be done?

Answer 1

BeforeEach httpBackend.when httpBackend.expect. , () BeforeEach, it(). , lRequestHandler. 200 , . httpBackend :

httpBackend.when("GET", "/solr/users/select?indent=true&wt=json").respond({});

:

    describe("method test", function () {
        it('scope.user should be defined: ', function () {
            expect(scope.user).toEqual({});
        });
    });
