Depending on what the test is, a %Q{ } pair might work better. You
will have to escape any '}'.

a = [
%Q{\
Multi line
  white      space is kept.
My here doc clone "can have quotes" 'of' any kind.},

%Q{\
just remember to use a \} to close
your text}
]

Personally, I don't care for heredoc format so i don't use it often.
