I use PHPUnit with Jenkins. PHPUnit outputs many "stty: standard input: Inappropriate ioctl for device." like this
[***] $ /bin/sh -xe /tmp/jenkins3872195701082406677.shÂ
+ vendor/bin/phpunit tests/
PHPUnit 5.7.22 by Sebastian Bergmann and contributors.
stty: standard input: Inappropriate ioctl for device
...
What should I do to suppress this message?
