Exploratory testing on 3.16 about wp-rocket HOT 7 CLOSED

CDN exploratory test results reported here

from wp-rocket.

How it works with video + preview image?: “To investgiate to understand, not necessarily to fix” Insert a video in a page/post and enable the preview image option on WP Rocket. Check how the LCP would work on this ; also check in case this is the ATF -> Ideal scenario is that the optimized element on the front-end would be the preview image

If this is a LCP, I get this result in the DB: {"type":"img","src":"https:\/\/i.ytimg.com\/vi\/HPFyrgMl9uE\/hqdefault.jpg"}. when reloading the page, It doesn't seem to do anything more. The preview image gets lazyloaded.

If it is a ATF, it still gets lazyloaded. Doesn't seems to do anything more on the image from the video.

Pages in a background tab? What if we open the page with Ctrl+Click and don’t visualize the page? What happens to the beacon script?

The beacon script seems to work properly as I get coherent result saved in the DB.

Import new settings in old version/old settings in new version while rucss on/off. Export/Import from 3.15->3.16: no errors/no warnings ; if possible, all settings should be preserved.

Exported settings from 3.15.10 with RUCSS enabled/disabled are imported correctly with no error/warning and all settings are preserved.

If lcp is next-gen while imagify is used and serving/not serving images. make sure we identify and optimize the right image that is actually served.

LCP candidate is correctly identified and optimized with Display images in Next-Gen format on the site enabled/disabled.

How it works with sliders and image image carousels? “To investgiate to understand, not necessarily to fix”: same here. Sliders -> Install slider plugin and no visual reg./no errors.

Used Slick Slider Plugin.
PSI identifies either the page title or the layer of text within the slider component as LCP. In our DB,above_the_fold table, will be one of the images inside the slider/carousel identified as lcp. O/w no errors.

Element 0 opacity, Element with low entropy?. “To investgiate to understand, not necessarily to fix”: What happens with those elements on PSI? What about our beacon script?

• image with 0 opacity: PSI identifies h1 as LCP, in DB will be the zero opacity image identified as lcp
• low resolution / icon or blurry image: same results on PSI & DB
• heavily optimized images: same results on PSI & DB
