        this._currentElement = {props: initialProps};
        this._rootNodeID = 'test';

      Object.assign(NodeStub.prototype, ReactDOMComponent.Mixin);
      genMarkup = function(props) {
        var transaction = new ReactReconcileTransaction();
        return (new NodeStub(props))._createContentMarkup(
          transaction,
          props,

        );

        },

    it('should handle dangerouslySetInnerHTML', function() {
      var innerHTML = {__html: 'testContent'};
      expect(
