They’ve had two falcon 9 systems explode unintentionally. The CRS-7 system failed in flight, and AMOS-6 failed on the launch pad during fueling. They also unintentionally blew up a Crew Dragon capsule.
It is true that they do testing differently from Boeing. Boeing uses a NASA testing plan where hardware is verified on the ground through extensive part or subsystem-level testing. This method has a downside which is that many things end up needing a higher factor of safety than absolutely necessary due to uncertainty in the risk calculations.
SpaceX uses a different testing strategy where a lot more stuff is tested as a complete system. There is increased potential for full system failures, which we have seen, but the entire system can be vetted more quickly.

I'm sure they are tested as integrated systems, but they are also exercised extensively ahead of that. The Super Dracos used for the launch escape system have been test-fired since well before the Crew Dragon got its name.
- BurnGpuBurn 7y agoWait, Boeing does testing? Should've done that with MCAS then.
- m4rtink 7y agoJust adding that AMOS-6 actually failed ruing fueling failed before a planned hot fire test, not during fueling before a planned launch. Due to that, it was not on an official live stream. Though I think it was recorded by at least one unofficial one covering the hot fire.
