# description: Test if we get unbuffered stdout, stderr, and logfile output.
# This is important, to see output during a long running step and
# not only at the end.
# see also: example.buffer
# The following tests are included:
# (1) check ia_out
# (2) check ia_logout
# (3) check ia_logerr
# (4) check exit,ia_out
# (5) check exit,ia_logout
# (6) check exit,ia_logerr
