# #
# Variable Name: slow_launch_time #
# Scope: SESSION #
# Access Type: Dynamic #
# Data Type: NUMERIC #
# Default Value: 2 #
# Values: - #
# #
# #
# Creation Date: 2008-03-02 #
# Author: Sharique Abdullah #
# #
# Last change: 2008-09-09 mleich Reimplementation of this test #
# - Fix Bug#36874 : main.slow_launch_time_func test fails #
# randomly #
# - Fix other failures and streamline the test #
# #
# Description: Test Cases of Dynamic System Variable "slow_launch_time " #
# that checks behavior of this variable in the following ways #
# * Functionality based on different values #
