How to use Laika test Meteor router or Iron router

var assert = require('assert');

 suite('Router', function() {
 test('navigate', function(done, server, client) {
 client.eval(function() {
 Meteor.Router.to ('test');
 var title = $('h1').text();
 emit('title', title); 
 })
 .once( 'title', function(title) {
 assert.equal(title,'Test');
 done();
 });
 });
 });

var page = require('webpage').create();

page.open('http://localhost:3000/ test', function () {
 ... 
}

// route to /some/path
client.evalSync(function() {
 // react on route change
 Deps.autorun(function() {
 if (Router.current().path =='/some/path') {
 emit(' return');
 this.stop();
 }
 });
 Router.go('/some/path');
});< /pre> 
Since this is in evalSync(), everything after this block will be executed after the routing is complete. Hope this helps.
 

I I am using laika for testing and meteor-router encapsulation for wiring. I want to do some tests to navigate to a certain page, fill out a form, submit it and check the success message, but I still stick to the navigation part. This is my number one Attempts:

var assert = require('assert');

suite('Router', function() {
 test('navigate', function(done, server, client) {
 client.eval(function() {
 Meteor.Router.to('test');
 var title = $('h1').text();
 emit('title', title); 
 })
 .once('title', function(title) {
 assert.equal(title, 'Test');
 done();
 });
 });
});

This does not work because Meteor.Router .to has no callback, and I don’t know how to execute the next line when loading a new page.

I also tried something like this

var page = require ('webpage').create();

page.open('http://localhost:3000/test', function () {
 ... 
} 

But I get the error error: Cannot find module'webpage'

Edit

I want to go to iron router, so any answers will be helpful.

I have the same problem. Before running the test, I need to navigate to a certain page. I am also using iron router. I think you can’t just execute Router.go('foo'), that's it. You need to wait until the actual routing occurs. Fortunately the router exposes a method Router.current(), which is a passive data source that will change once your page is ready. Therefore, in order to navigate to a specific route before running the test, I first run the following code block:

// route to /some/path
client. evalSync(function() {
 // react on route change
 Deps.autorun(function() {
 if (Router.current().path =='/some/path') {
 emit('return');
 this.stop();
 }
 });
 Router.go('/some/path'); 
});

Since this is in evalSync(), everything after this block will be executed after routing is complete. Hope this helps.
