Help Test Controller Angularjs and Jasmine

Question

Good morning guys, I need a help to do the unit test of a controller with Jasmine, my problem is that I need to cover the methods of this controller and I am not able to do the right way to get through all lines of code. The controller is this below.

'use Strict'; angular.module('cadastarUsuario.module') .controller('user control', Function (messagesService, sharedService, register Uservice) { var vm = this; vm.cadastrarUsuario = _cadastrarUsuario; vm. vm.dataCadastro = { indicatorExistence: ' }; vm.data vm.TELAS = sharedService.TELAS; vm.tela = vm.TELAS.INICIO; vm.confirm = _confirm; vm.back = _back;

        function _cadastrarUsuario() {
            cadastarUsuarioService.consultarCPF(vm.dados)
                .then(function (dados) {
                    if (dados.indicadorExistencia == 0) {
                        vm.dadosCadastro = dados.titulares[0];
                    }
                    vm.dadosCadastro.indicadorExistencia = dados.indicadorExistencia;
                    sucessoTransacao(vm.TELAS.CONFIRMACAO);
                }, function (e) {
                    mensagemService.error(e.error);
                });
        }

        function sucessoTransacao(tela) {
            vm.tela = tela;
            _subirRolagem();
        }

        function _subirRolagem() {
            window.parent.scroll(0, 0);
        }

        function _confirmar() {
            cadastarUsuarioService.cadastrarNovoUsuario(vm.dadosCadastro)
                .then(function (dados) {
                    vm.dadosResposta = dados;
                    sucessoTransacao(vm.TELAS.EFETIVACAO);
                }, function (e) {
                    mensagemService.error(e.error);
                });
        }

        function _voltar() {
            vm.tela = vm.TELAS.INICIO;
        }

    });

At the exit of the corevage is getting like this:

I don’t know how to make the code to go through as many lines as possible in this code, could someone please put an example of how to write this test? I would be very grateful, remembering that I am beginner with tests with Jasmine and still do not have all the necessary knowledge to do this test.

The test I wrote was like this, this was as far as I could get, which was to get to the . then of _cadastrarUsuario.

describe('', Function () {

beforeEach(module('app.core'));
beforeEach(module('sharedService.mock'));
beforeEach(module('mensagemService.mock'));

    module(function($provide) {
        $provide.service('serviceCfeHTTP', function() {
            this.post = function(url) {
                return 80;
            }
        });
    });
 
    //Inject da controller e das services mock utilizadas por ela.
    inject(function ($q, _$controller_, _mensagemServiceMock_, _sharedServiceMock_, _cadastarUsuarioService_) {
        q = $q.defer();
        $controller = _$controller_;
        mensagemServiceMock = _mensagemServiceMock_;
        sharedServiceMock = _sharedServiceMock_;
        cadastarUsuarioService = _cadastarUsuarioService_;
    });

    //Referencia das services mock usadas pela controller 
    usuarioController = $controller('cadastarUsuarioController', {
        mensagemService: mensagemServiceMock,
