# This script reads json files given in the command-line (each file
|
|
# must be written in the format described in
|
|
# https://github.com/Jxck/hpack-test-case). And then it decompresses
|
|
# the sequence of encoded header blocks (which is the value of 'wire'
|
|
# key) and checks that decompressed header set is equal to the input
|
|
# header set (which is the value of 'headers' key). If there is
|
|
# mismatch, exception will be raised.
