示例1: test_from_sys_path_device_not_found
# 需要导入模块: from pyudev import Devices [as 别名]
# 或者: from pyudev.Devices import from_sys_path [as 别名]
def test_from_sys_path_device_not_found(self, a_context):
sys_path = 'there_will_not_be_such_a_device'
with pytest.raises(DeviceNotFoundAtPathError) as exc_info:
Devices.from_sys_path(a_context, sys_path)
error = exc_info.value
assert error.sys_path == sys_path
assert str(error) == 'No device at {0!r}'.format(sys_path)示例2: test_from_sys_path
# 需要导入模块: from pyudev import Devices [as 别名]
# 或者: from pyudev.Devices import from_sys_path [as 别名]
