Google has announced of grouping and rebrading the terms it used over the years to highlight website's content in the search results, such "rich snippets, rich cards, or enriched results" into more simplified terminology for all of them called "rich results."
In addition, Google has also launched a new version of its structured data testing tool for rich results testing to help diagnosing web pages' structured data more easier.
The new rich results testing tool, as Google says "focuses on the structured data types that are eligible to be shown as rich results." This new version of the tool enables users to test all data sources on your pages, like the recommended JSON-LD, Microdata, or RDFa.
Furthermore, Google said, this new tool offers more "accurate reflection of the page's appearance on Search and includes improved handling for Structured Data found on dynamically loaded content."
The tools in its initial stage currently only support to test for Recipes, Jobs, Movies, and Courses. But, support for other rich results is planned for adding later over the time.
The screenshot below shows the new testing tool and works on both desktop and mobile:
In order to test a page, just head over to this page, and enter a URL of the website to begin a test, once the test complete, you can review the output.
All the issues dectecd by the tool will highlight the invalid code in the page source. Additionally, using a preview button, you can view all the different rich results the page is eligible for.
The testing page will also show a share-icon on the bottom-right, so you can work with others quickly to remedy the issues. Once you're done with the result, tap on the "Submit To Google" button to fetch & index the page to include it in the search results, says Google.
