If that "100s of MB" is acceptable to be in memory, then bufio.Scanner with properly sized scanner.Buffer is the easiest and battle tested solution.
If not, then you have to reimplement the same, with a temp file as a buffer: read input, store in file, seeking to the start on each '\n', copying the file to STDOUT when "test" is found. Not too hard, but have a few edge cases.
