code: function(element, transformAttr, expectedCss) {
      var testDiv = angular.element('<div>');
      testDiv.css(transformAttr, expectedCss);
      expect(element.css(transformAttr)).toBe(testDiv.css(transformAttr));
    }
docs: Verifies that an element has the expected CSS for its transform property.
  Works by creating a new element, setting the expected CSS on that
  element, and comparing to the element being tested. This convoluted
  approach is needed because if jQuery is installed it can rewrite
  'translate3d' values to equivalent 'matrix' values, for example turning
  'translate3d(240px, 120px, 0px) scale(0.5, 0.5)' into
  'matrix(0.5, 0, 0, 0.5, 240, 120)'.
