Ruby on Rails

Hello,

I want to test the contents of the p tag here :

~~~

<div class="productinfo text-center">
                                              <%= image_tag product.image_url %>
                                              <h2><%=number_to_currency(product.price)%></h2>
                                               <p> <%= product.title %>   </p>
              <a href="#" class="btn btn-default add-to-cart"><i class="fa fa-shopping-cart"></i>Add to cart</a>
          </div>

~~~

I tried this assert_select'.single-products.p',1 but it do not work. I get 0 items found .
