Yeah, it's not a good look, though at this point in the program some engine test failures would be expected:

During a firing on June 30 at a West Texas facility of Jeff Bezos' space company, a BE-4 engine detonated about 10 seconds into the test, according to several people familiar with the matter. Those people described having seen video of a dramatic explosion that destroyed the engine and heavily damaged the test stand infrastructure.
The people spoke to CNBC on the condition of anonymity to discuss nonpublic matters.
The engine that exploded was expected to finish testing in July. It was then scheduled to ship to Blue Origin's customer United Launch Alliance for use on ULA's second Vulcan rocket launch, those people said.
A Blue Origin spokesperson, in a statement to CNBC on Tuesday, confirmed the company "ran into an issue while testing Vulcan's Flight Engine 3."
"No personnel were injured and we are currently assessing root cause," Blue Origin said, adding "we already have proximate cause and are working on remedial actions."
This was to go on the flight with the SNC Dreamchaser launch, and I guess it's a good thing this happened on the test stand vs. 2,000 or so feet off the launch tower.
https://www.space.com/blue-origin-be-4-rocket-engine-explosionIt was during acceptance testing, which is why they do acceptance testing. Obviously not ideal, especially compared to the testing reliability of SpaceX engines (something like 1600 Raptor tests?!?!).
I have no idea what cadence they are cranking out BE-4 engines, but I know it's nowhere near SpaceX. If one engine fails and that affects many other programs, then that's a huge logistics issue for sure.
And if they can't find the root cause of the failure, that's also a huge issue. Will be interesting to see how this plays out.
