When a TTY is attached to the test unit, grep -q will generate SIGPIPE for the previous command in the pipeline which in combo with `pipefail` will cause the command to fail with exit status 141 which will fail the test. Replace with >/dev/null to avoid this from happening. See also https://www.gnu.org/software/grep/manual/html_node/Usage.html > There is a related problem with Bash’s set -e -o pipefail. Since grep > does not always read all its input, a command outputting to a pipe read > by grep can fail when grep exits before reading all its input, and the > command’s failure can cause Bash to exit.
