Google Rich Snippets (Schema.org) ratings not working

Question

I tried to place a small piece of code and tested it in the Google Structured Data Testing tool, but no bright fragments appeared.

Here is a screenshot of what I mean:

And here is the piece of code that I used that I took directly from Schema.org:

<div itemscope itemtype="http://schema.org/Product">
    <span itemprop="name">Product name</span>
    <div itemprop="aggregateRating"
            itemscope itemtype="http://schema.org/AggregateRating">
        Rated <span itemprop="ratingValue">5</span>/5
    </div>
</div>

Any ideas why it didn't appear in the testing tool?

Thanks Baggio

For aggregate review ratings, as opposed to one review, you must indicate the total number of reviews, of which ratingValuethe average is using reviewCount. Using your code as a base:

<div itemscope itemtype="http://schema.org/Product">
<span itemprop="name">Product name</span>
<div itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating">
   Rated <span itemprop="ratingValue">5</span>/5
   Based on <span itemprop="reviewCount">100</span> reviews
</div>
</div>

Based on <span itemprop="reviewCount">100</span> reviews

. 1 , count Google. ( ).
