title: Test canvas drawings with Protractor
body: <p>Is there a way to <strong>test if a drawing was made on a canvas using Protractor</strong>?</p>
  
  <p>i.e. I draw a rectangle based on user clicks:</p>
  
  <pre><code>var shape = new createjs.Shape();
  shape.graphics.beginStroke("black");
  shape.graphics.drawRect(crd.x, crd.y, crd.width, crd.height);
  stage.addChild(shape)
  stage.update()
  </code></pre>
  
  <p>Now I want to make a spec to test if a rectangle was drawn on the specified coordinates and, as a plus, to test if its borders are of color black.</p>
  
  <p>Is this possible using Protractor/WebDriverJS API?</p>
