What it is
A short official SpaceX clip showing a full-duration static fire of a Falcon 9 first stage, the booster from the May JCSAT mission, on the horizontal test stand at the company's McGregor, Texas development facility. It is raw test footage with no narration.

Cites David says Reinstate Monica · 2016-07 · Space Exploration Stack Exchange · on “Why doesn't this SpaceX rocket test fire use water sprays?”
I know that rocket launches always have water towers spray water all around when the rocket is launching to suppress the extreme sounds and shockwaves generated by the launch and ensure the rocket doesn't tear itself apart. But in this [this video] video of a test fire no water towers are visible. How does SpaceX prevent damage from vibrations in this case?
Cites Aditya Oktaviandra · 2016-11 · Space Exploration Stack Exchange · on “What is the new horizontal test stand at SpaceX's McGregor, TX facility meant to test?”
Looks like now it has been answered (though not officially), but here's a video from SpaceX with JCSAT-14 booster test. In this video, you can clearly see the test stand and you also can see it looks like also designed with three core Falcon Heavy.
Cites karthikeyan · 2018-08 · Space Exploration Stack Exchange · on “Which of the orientation is preferred for static fire testing of a liquid rocket engine - vertical or horizontal?”
Liquid rocket engine's hot fire testings are performed both vertically and horizontally. Vertical orientation - Falcon heavy [LINK] , Falcon 9 [this video] , Rutherford engine [LINK] , UCSD Engine test from 2014 [LINK] , Merlin 1D [LINK] , MASA UMich [LINK] Horizontal orientation - UCSD Engine test from 2015 [LINK] , Launcher Space Test [LINK] , Masten Space system test [LINK] , Armadilo Aerospace [LINK] , SpaceX's Raptor [LINK] What is the basis of the testing orientation - from the point of view of safety, size, complexity (or ease of operation), data collected, etc.? NOTE: There appears to a trend wherein low thrust engines are preferred to be tested horizontally while high thrust engines are
