net-driver-test

This is a set of scripts for testing Linux network device driver functionality.

These scripts are intended to be used with rapido to test the driver in a VM.

Some advantages to this test approach include:

• the host is protected from memory corruption errors caused by buggy kernel drivers;
• the PCI peripheral can be physically installed in a multi-use machine, reducing hardware & lab requirements;
• debugging info is easily available;
• the development cycle is short and simple - rapid even :)

PCI Passthrough is required to be able to assign the real hardware peripheral to the VM.

These tests implement the Kernel Test Anything Protocol (KTAP) to format test results.

Usage:

1. Clone the repo
2. Create a test script to run start.sh. Example below.

Using with rapido:

#!/usr/bin/bash

if [[ $(id -u) -ne 0 ]]; then
        echo "Run this script as root"
        exit 1
fi
