Google’s updated Structured Data Testing Tool now offers previews when you submit a URL or code snippet for testing. This means you can check and see what your markup would look like in the search results without having to wait for it to go live.
The preview functionality only works for some types of schema – both product and recipes are supported.
To view the preview, you actually need to click through to the specific schema type from the test results.
If the preview option is available, it will show then.
It seems to be designed specifically for those checking mobile schema, as it states it is “Best viewed on mobile devices” and it includes AMP previews.
When you click through to “View all”, you see the detailed view version.
Here is an example from a product markup:
There could be other schema types that are supported but this are the only two I saw.
Google previously had a preview tool many years ago, but it had been removed.
You can access it via the Google Structured Data Testing Tool.

The preview tool shows nicely the rating, price, availability, but on google search results page they do not appear. Is Google just not showing them for some reason?
Jennifer Slegg says
If the implementation is correct, it is a quality issue then. If they show in a site: search but not in the regular search results, Google has deemed the site to not be of high enough quality to show the markup.
