From 2454f51b2742daec05307c0138d2c1db2107412d Mon Sep 17 00:00:00 2001 From: Timo Tijhof Date: Mon, 17 Jul 2017 15:21:54 -0500 Subject: [PATCH] Upgrade QUnit from v1.23.1 to v2.4.0 Source https://code.jquery.com/qunit/qunit-2.4.0.js https://code.jquery.com/qunit/qunit-2.4.0.css Changelog https://github.com/qunitjs/qunit/blob/2.4.0/History.md This release makes 'moduleStack' private, which means we can no longer use it to detect nested modules. Change the method of detection to be a local 'nested' variable that we toggle in a wrapped version of any 'executeNow' callback, in which nesting happens.
