Reply to comment by New_Poet_338 in SpaceX on Twitter: Super Heavy Booster 7 completed a full duration static fire test of 31 Raptor engines, producing 7.9 million lbf of thrust (~3,600 metric tons) – less than half of the booster’s capability by allforspace

There's also full (launch) duration testing. Doing a full duration test with an engine is often about essentially simulating a launch, ensuring that you can sustain the performance you need for the requisite amount of time.

They did that for SLS but the first flight of SLS was a mock production flight. The first flight of SS will be a test flight. There is no chance the infrastructure at Boca Chica would survive that.
