Test running python on remote device nodes

[mbanders]

Is the idea you would still connect to the WAN device normally with pexpect? You'd just have a test that also used Pyro (or similar) to run python on the WAN device?

[mattsm]

I think pyro would connect via some sort of network connection and not over pexpect. pexpect would still be present. Maybe the pyro session would be added to the pexpect object.

def foobar():
.... some native python to run on target device ....

wan.pyro.invoke(foobar)

Looks like it just connects via a port

We can probably use ssh to forward a port so we don't need to worry about opening new ports?

@mattsm looking at Pyro4 documentation, it seems like the code has to be present on the remote device (or wan device in this case). So an outline of the process seems like it would be:

1. the machine running bft runs a test, and within that test, copies a python file on the wan device.
2. The test then connects and
3. starts the code in that python file

Does that sound about right?

I was hoping to avoid copying, I wonder if there is a way to do that... the latter parts look correct. Might search for some alternative python remoting frameworks as well.

After research @mbanders says there is no great solution... pyro4 requires copying files over.
