Is it possible to run the unittests of a module with -betterC 
like

     dmd -D -g -main -unittest -betterC f.d

?

This currently errors as

/usr/include/dmd/druntime/import/core/internal/entrypoint.d:34: error: 
undefined reference to '_d_run_main'

for an empty file f.d

AFAIK no,

https://dlang.org/spec/betterc.html#unittests

-unittest sets the 'unittest' version identifier. So this works:

  unittest {
     assert(0);
  }

  version(unittest) {
      extern(C) void main() {
          static foreach(u; __traits(getUnitTests, 
__traits(parent, main)))
              u();
      }
  }

dmd -betterC -unittest -run module.d
