Are @safe unittests actually checked for safety?

Are unittests that are marked @safe actually checked for safety?


https://github.com/dlang/phobos/blob/v2.093.1/std/file.d#L4937
How comes this unittest is @safe when `dirEntries` appears to be 
@system?


Example I:

https://run.dlang.io/is/Vf0STw
>  Error: @safe function onlineapp.listdir cannot call @system 
> function std.file.dirEntries


Example II (by adr):

> int* a = cast(int*) 0xdeadbeef;
> also was allowed..
> making me think @safe unittest doesn't actually check the safety

PS: is there a @safe version of `dirEntries`?
