Google posted on Webmaster central blog that it is introducing of new version of structured data testing tool in order to make diagnosing your pages’ structured data easier.
A common terminology of “rich results” will be used for rich snippets, rich cards, and enriched results.
Google said the new testing tool “focuses on the structured data types that are eligible to be shown as rich results.” it would allow you to test all data sources on your pages, including the recommended JSON-LD, Microdata or RDFa. Google said this new version is a “more accurate reflection of the page’s appearance on Search and includes improved handling for Structured Data found on dynamically loaded content.”
Currently, only the tests for Recipes, Jobs, Movies, and Courses are supported. However, Google plans to expand over time.
Here is a screenshot of the tool, which works equally good on mobile and desktop:
