From becc3ec372baeef0a4b89923968d874010966c49 Mon Sep 17 00:00:00 2001 From: Ruben Bridgewater Date: Mon, 14 May 2018 16:16:33 +0200 Subject: [PATCH] test: remove common.globalCheck This flag is partially used in tests where it was not necessary and it is always possible to replace this flag with `common.allowGlobals`. This makes sure all globals are truly tested for.
