# Virtual¶

The virtual interface can be used as a way to write OS and driver independent tests.

A virtual CAN bus that can be used for automatic tests. Any Bus instances connecting to the same channel (in the same python program) will get each others messages.

import can

bus1 = can.interface.Bus('test', bustype='virtual')
bus2 = can.interface.Bus('test', bustype='virtual')

msg1 = can.Message(arbitration_id=0xabcde, data=[1,2,3])
bus1.send(msg1)
msg2 = bus2.recv()

assert msg1 == msg2
