This patch decreases the locally test run from 14.5 to 2.4 seconds.

Awesome!

Are we loosing coverage here for view access on render?

Ah ok then, thats the only thing I could think of, and the rest looks great- so RTBCing :)

@claudiu.cristea the access thing here feels tricky. If you comment out user_role_grant_permissions(RoleInterface::ANONYMOUS_ID, ['access comments']); in the original test it still passes so you're right that access is not being tested but should it be being tested? The only thing in CommentViewsData I can find is $data['comment_field_data']['table']['base']['access query tag'] = 'comment_access'; and that's not being tested here (or anywhere else for that matter).

Committed 3a1d204 and pushed to 8.8.x. Thanks!

Will backport to 8.7.x later.
