Service:

myApp.factory('UserApi', ['$http', function($http) { var checkCredentialsUrl = '....'; return { checkCredentials: function(user, pass) { return $http({ method: 'POST', data: { jUser: user, jPass: pass }, 'headers': { 'Content-Type': 'application/x-www-form-urlencoded' }, transformRequest: function(obj) { var str = []; for(var p in obj) str.push(encodeURIComponent(p)+"="+encodeURIComponent(obj[p])); return str.join("&"); }, url: checkCredentialsUrl }); } } }]);

Test:

 describe('UserApi', function () { var UserApi, $httpBackend, user, pass, checkCredentialsUrl, succeeded = false; beforeEach(module('myApp')); beforeEach(inject(function (_UserApi_, _$httpBackend_){ UserApi = _UserApi_; $httpBackend = _$httpBackend_; checkCredentialsUrl = '...'; user = 'qwerty'; pass = 'qwerty'; })); afterEach(function() { $httpBackend.verifyNoOutstandingExpectation(); $httpBackend.verifyNoOutstandingRequest(); }); describe('Auth', function () { it('CheckCredentials', function () { $httpBackend.expectPOST( checkCredentialsUrl, { jUser: user, jPass: pass }, function(headers) { return headers['Content-Type'] === 'application/x-www-form-urlencoded'; }).respond(200); UserApi.checkCredentials(user, pass).then(function(response){ succeeded = true; }); $httpBackend.flush(); expect(succeeded).toBe(true); }); }); });

If you remove the transformRequest section from the service, then the test works.
Tell $httpBackend how to tie transformRequest to $httpBackend ?

    Oddly enough, but enough to replace:

     $httpBackend.expectPOST( checkCredentialsUrl, { jUser: user, jPass: pass }, function(headers) { return headers['Content-Type'] === 'application/x-www-form-urlencoded'; }).respond(200);

    On:

     var data = { jUser: user, jPass: pass }; $httpBackend.expectPOST( checkCredentialsUrl, function (data) { return data; }, function(headers) { return headers['Content-Type'] === 'application/x-www-form-urlencoded'; }).respond(200);

    The reason did not begin to disassemble, the test wound up.
    If anyone explains in the comments, add to the answer.

    Thanks to everyone who came.
