"""
The ideas behind these test and the named templates is to ensure consistent output
across all supported different scenarios:

TODO: cover more scenarios
 * terminal vs. redirect stdout
 * different combinations of `--print=HBhb` (request/response headers/body)
 * multipart requests
 * streamed uploads
