From 1f335d18e57ba9494e09184008ce7eccfd6755c9 Mon Sep 17 00:00:00 2001 From: Robert Foley Date: Wed, 1 Jul 2020 14:56:17 +0100 Subject: tests/vm: pass args through to BaseVM's __init__ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adding the args parameter to BaseVM's __init__.
