From 941ee147f92b6064b5e5feff166ecfb97cea85b1 Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Tue, 22 May 2018 22:08:50 +0200 Subject: tests: remove gmm unit tests The test cases now implemented by TTCN3 which should not be as fragile as the unit tests. Because the unit tests expect a quite strong internal state to be happen.
