# `bats-core` will consume both stdout and stderr for the `run` command's output.
|
|
# However `jq` prints its DEBUG output on stderr.
|
|
#
|
|
# Lines starting with `["DEBUG:",` will be prefixed with a hash and printed on file descriptor 3.
|
|
# Other lines on stderr will remain on stderr for bats to consume.
