How do I get Nightwatch to show Chai assertions in the reporter?

Question

I'm using Nightwatch JS v0.9.16 to run selenium / chai tests on my localhost. All the assertions work for nightwatch, but I can't get the chai assertion to show in the reporter.

This issue has been discussed here: https://github.com/nightwatchjs/nightwatch/issues/601 however it's been closed but there was no resolution... can anyone get this to work yet?

Here's my test:

var assert = require('chai').assert;

module.exports = {
  'pressing the "Servers" tab should change the URL to #servers' : function (client) {
    const pages = client.page,
          home_page = pages.home(),
          servers_page = pages.servers();

    home_page.navigate();
    servers_page.expect.element('body').to.be.present.before(1000);
    client.pause(1000);
    servers_page.click('@nav');
    servers_page.expect.element('@servers_div').to.be.present.before(1000);
    client.url(function(response){
        var currentUrl = response.value.replace(client.launch_url,"");
        console.log("url is ",response.value);

        //***CHAI ASSERTION doesn't get shown on reporter:***
        assert(currentUrl.indexOf('#servers')!=-1);

        client.end();
    });

  }
};

Screenshot of when this test passes shows all the assertions except the chai one:

And when it fails it shows AssertionError: Unspecified AssertionError:

According to the doc, assert() takes a message as 2nd arg (http://www.chaijs.com/api/assert/), did you try it out? If so, was the message displayed?

Alternatively, have you tried with simpler tests (one failing, one not) for example: assert.isOk(false) & assert.isOk(true)?

Last, did you try running your chai assertion outside of client.url() 's callback?

I am not familiar with Nightwatch, but that's what I would have tried.
