Engines are also tested for speeds and altitudes where birds are typically encountered - ie, not Mach 0.8 at FL35. Canopy tests are similar.
If I’m remembering correctly, I think the typical “speed limit” is 250 kts below Class A airspace, which is a far cry from a Mach number.
edit: I also recall that the testing allows for destruction of the engine as long as shrapnel does not penetrate the fuselage. Engines are not happy ingesting a goose regardless of speed or altitude. There’s a liner surrounding the turbine blades the must remain intact to pass the test.
