# if we want to use some key sequence in the test, we first need to test
# that it itself does what it is expected to do. Most of the tests are
# designed that way.
#
# example: "arrows & delete test 1". we enter a partially valid command,
# then move 3 chars left and use delete three times. this way we get to
# know that "delete", "left" and "ctrl+B" all work (because if any of
# them fails, the whole test will fail and next tests won't be run).
#
# each test consists of name, character sequence to send to child,
# and expected output (if any).
