really? I get: sed: line number 0 is illegal

for this one: 

>{echo test; echo test1; echo test2} | sed '1,/^test$/d' # has no output

it deletes line 1, then continues deleting lines until it finds ^test$
which it never does. Perhaps adding a newline at the start is the quickest
way to get what you want?

{echo; echo test; echo test1; echo test2} | sed '1,/^test$/d'

test1
test2
