angularjs - Angular 1.5 unit test controller that requires parent component's controller -

i'm trying unit test (child) controller of angularjs 1.5 (with webpack) component requires parent component , controller module.

child controller structure:

function childcontroller () {   var vm = this;    vm.searchtext = '';    vm.submit = function() {     var data = {};     data['srch'] = vm.searchtext;     vm.parentctrl.submittextsearch(data);   }; }  module.exports = childcontroller; 

child component:

var template = require('./child.html'); var controller = require('./child.controller');  var childcomponent = {   require: {     parentctrl: '^parent'   },   template: template,   controller: controller,   controlleras: 'vm' };  module.exports = childcomponent; 

so mock out parentctrl that's required in childcontroller's submit()-function. i've been unable find how this. i've found similar child-parent directive solutions , tried those, e.g. injecting parent controller through fake html-element described in this child-parent directive example , same stackoverflow solutions no results. problems differ @ least in fact child , parent controller in different modules. , suppose scope-tricks not angular 1.5-style?

the skeleton of jasmine test without failed mock attempts:

describe('child component', function() {   describe('child controller', function() {     var controller;     beforeeach(angular.mock.module('child'));     beforeeach(inject(function(_$componentcontroller_) {       controller = _$componentcontroller_('child');     }))     it('should work', function() {       controller.searchtext = "test";       controller.submit();     })   }) }) 

that results in typeerror: cannot read property 'submittextsearch' of undefined. should mock parent controller out? limited experience in angular, i'm out of ideas.

in case you're add parentctrl dependency of component in order test have mock parent component , assign controller. you'd need like:

beforeeach(inject(function(_$componentcontroller_) {   controller = _$componentcontroller_('child');   parentctrl = _$componentcontroller_('parent');   controller.parentctrl = parentctrl; }))
