It seems to me you just missed some basic syntax (?).

You can write:

:augroup MyTest
:augroup END
:augroup dave
:augroup END

" clear existing autocmds of each group:
:autocmd! MyTest
:autocmd! dave

" add autocommands
:autocmd MyTest FocusGained * :if has('clipboard') | echomsg "has clipboard" | endif
:autocmd dave User Test :echomsg 'It works!'
