Why BaseDevice class is derived from (pexpect.spawn):

[mirafratech]

Hi Matthew/All,
Could someone please help me to understand the below issue in boardfarm framework

I have been going through board farm framework code for a while and found that the BaseDevice class from base.py is inheretied from pexpect.spawn

class BaseDevice(pexpect.spawn):

And when I am trying to remove the inherited base class from my DebainBox class I am facing the below Error

from class DebianBox(base.BaseDevice):
to
class DebianBox():

Error Snippet:
unbound method init() must be called with spawn instance as first argument (got DebianBox instance instead)
Failed to connect to any device

These changes is needed for me to use Paramariko as my connection interactive_tool instead of pexpect to achieve dynamism in using connection modules(like pepxect or paramiko or telenetlib)

Could you please guide me to solve over the problem and Is it possible to make the connection to device independent of the pexpect module.

Thanks a lot ,
