If you are still working on getting your pages AMP ready, the AMP related reporting in Google Search Console can be a bit frustrating since the error reporting is quite delayed.  And while the structured data testing tool can help show errors, it isn’t as intuitive for AMP, especially for those with little experience with the tool.

Google has taken these factors into account and created a new AMP testing tool, which makes it easy for site owners to test and debug their AMP pages.  And it makes it very obvious if a page is AMP or not.

Here is an example of the test:

One downside is that you have to know the exact AMP URL.  Even if AMP canonicals are set up properly, it will test the exact URL entered, and will not automatically go to the AMP version of the page for testing.  It would have been an added bonus if it added a “We see an AMP canonical, would you like to test the AMP version of this page?” or something similar.

Here is how it looks for a failed AMP test:
