From 1681ba53783835e500e602a1b7500e0221eb08f9 Mon Sep 17 00:00:00 2001 From: Emma Foley Date: Thu, 22 Feb 2018 19:11:12 +0000 Subject: Update TaskParser to deal with qualified name in Context The context name depends on the defined name in the testcase input file, the task ID and the flags of the context. If the context is going to be undeployed at the end of the test, the task ID is suffixed to the name to avoid interferences with previous deployments. If the context needs to be deployed at the end of the test, the name assigned is kept. This patch makes this process transparent to the developer. This patch modifies how TaskParser determines the correct context name, taking into account that the name might change based on context flags.
