 Writing tests
 -------------
 
-* Import ``resources/mocha.html`` and ``resources/chai.html``
-* Write tests in [mocha format](http://mochajs.org/#getting-started) and use [chai asserts](http://chaijs.com/api/assert/):
-```html
-describe('My pretty test of my subject', function() {
-  var subject = new MySubject();
-
-  it('should be pretty', function() {
-    assert.ok(subject.isPretty);
-  });
-});
-```
+* We recommend using the ``unittest.dart`` testing framework.
+* See ``sky/tests/lowlevel/attribute-collection.sky`` for an example.
