The DWARF assembler is in gdb/testsuite/lib/dwarf.exp.
It has a large comment that explains most of how to use it;
plus a few specific comments next to some exported procs.
Search gdb.dwarf2 for Dwarf::assemble for some examples.

In this case I think the test case is just testing that gdb reacts
properly when the DWARF has an invalid version.  This is simple to do
with the assembler; just pass something unusual to the "cu" proc.
