A set of Chai assertions ready for your DOM.

Installation

$ ember install ember-chai-dom-helpers

In your /tests/test-helper.js file, simply add :

import setupChaiDomHelpers from 'ember-chai-dom-helpers/test-support/setup';

setupChaiDomHelpers();

The assertion subject have to be one of the following:

  • A DOM element

Here's the helpers availables:

Rendered

expect('.something').to.be.rendered;
expect('.something').to.be.not.rendered;

Test the plain text content of the subject.

expect('.something').to.have.textContent('foobar');
expect('.something').to.not.have.textContent('foobar');

Test the html content of the subject.

expect('.something').to.have.htmlContent('<div>foobar</div>');
expect('.something').to.not.have.htmlContent('<div>foobar</div>');

Test the number of elements that matches the subject.

expect('.something').to.have.count(1);
expect('.something').to.not.have.count(1);

expect('.something').to.not.have.class('active');

expect('.something').to.not.have.localClass('active');
