Preview Chai.js based expect assertions

[beatfactor]

This is a preview of the new upcoming assertion library in v0.7 based on Chai.js. It provides a much more flexible syntax and style.

Example:

  client.url('http://google.com')

  client.expect.element('#lst-ib').to.be.enabled;
  client.expect.element('body').to.be.present.before(1000);
  client.expect.element('#lst-ib').to.have.css('display').matches(/block/).before(2000);
  client.expect.element('body').to.have.attribute('class').which.matches(/vasq$/);
  client.expect.element('#hplogo').text.to.match(/Norge/).before(1000);

  client.setValue('#lst-ib', 'Norway').pause(500);
  client.expect.element('#lst-ib').to.have.value.equal('Norway');
  client.expect.element('#lst-ib').to.be.an('input');
  client.expect.element('#lst-ib').to.be.not.selected;
  client.expect.element('#lst-ib').to.be.visible;

  client.end();
};

Out of curiosity why not check client.locateStrategy here?

It's on the TODO list :)

FYI: The main reason I picked nightwatch over the alternatives a couple of weeks ago was specifically the lack of any BDD-style API (which is BS, IMO).

Well, I can't say I'm a big fan of BDD but this offers much more flexibility and that's quite important.
