I think the problem is, that it is not categorized as ethernet device. But the test is checking for one Vmstat.ethernet_devices.size.should == 1. Since the data comes from /proc/net/dev, which doesn't have info regarding the type, type is detemined by the name. If you want the test to pass rename the interface to eth0.
