示例1: test_get_console_width_no_stderr_on_failure
# 需要导入模块: import subprocess [as 别名]
# 或者: from subprocess import py [as 别名]
def test_get_console_width_no_stderr_on_failure():
# run docker-make with a non-console standard input
# (inspiration from Python's subprocess.py)

assert b"ioctl for device" not in stderr 示例2: check_output
