Structured Data Testing Tool

  Google, Online Tools

You can test your source code for your schema by using the Schema Markup Validator. You can either have Google fetch the URL or paste the code snippet. Google recommends starting with the Rich Results Test. Rich results are experiences on Google surfaces like Search that go beyond the standard blue link. Rich results can include carousels, images, or other non-textual elements.
