Structured Data Testing Tool

Rich snippet testing tool, now called the structured data testing tool. 
The major improvements are:

• We’ve improved how we display rich snippets in the testing tool to better match how they appear in search results.
  

• The brand new visual design makes it clearer what structured data we can extract from the page, and how that may be shown in our search results.

• The tool is now available in languages other than English to help webmasters from around the world build structured-data-enabled websites.
