From 2b1999b7c7b32931b14cc8df554fc4fa46950ecc Mon Sep 17 00:00:00 2001 From: Rich Trott Date: Fri, 25 Dec 2015 21:52:52 -0800 Subject: [PATCH] test: remove unused vars in ChildProcess tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In addition to removing unused vars, this also fixes an instance where booleans were set presumably to check something but then never used. This now confirms that the events that were setting the booleans are fired.
