Re: what you forgot to test
>*cough* 737 MAX *cough*
Apples vs oranges. Although clearly not safe enough for commercial use, the 737 Max managed 8,600 successful flights per week while still in service. It is going to be a long time before SpaceX rockets a can be declared that safe.
Not criticizing SpaceX, space flight remains an inherently dangerous but worthy adventure. And will be so for some time yet.
