+*** Settings ***
+Documentation Beta Version of the Longevity Test. Currently:
+... 1. runs one iteration of the switch scale test based on ${NUM_SWITCHES}
+... 2. runs one iteration of the host scale test based on ${NUM_HOSTS}
+... Steps 1 and 2 are run in a psuedo infinite loop and before each loop is
+... run, a time check is made against the ${TEST_LENGTH}. If the test duration
+... has expired, the loop is exited and the test is marked PASS
+...
+... If either of steps 1 or 2 fail to reach their configured value of ${NUM_SWITCHES}
+... or ${NUM_HOSTS} the test will exit immediately and not continue.

+*** Keywords ***
+Check If There Is A Reason To Exit Test Or If Duration Has Expired
+ [Documentation] In order to simplify the main test case, this keyword will make all the neccessary checks
+ ... to determine if the test should FAIL and quit because of some problem. It will also return a bool to
+ ... indicate if the requested duration of the longevity test has elapsed. The caller does not have to use
+ ... that return value.
+ [Arguments] ${comparator1}=1 ${comparator2}=1 ${comparator_failure_message}=null
+ Should Be Equal ${comparator1} ${comparator2} ${comparator_failure_message}
+ Verify Controller Is Not Dead ${CONTROLLER}
+ ${is_expired}= Check If Test Duration Is Expired
+ [Return] ${is_expired}
+
+Check If Test Duration Is Expired
+ [Documentation] Compares the current time with that of the suite variable ${end_time} to determine if the
+ ... test duration has expired.
+ ${test_is_expired}= Set Variable False
+ ${current_time}= Get Current Date
+ ${current_time}= Convert Date ${current_time} epoch
+ ${test_is_expired}= Set Variable If "${current_time}" > "${end_time}" True
+ [Return] ${test_is_expired}
+
+Longevity Suite Setup
+ [Documentation] In addtion to opening the REST session to the controller, the ${end_time} that this
+ ... test should not exceed is calculated and made in to a suite wide variable.
+ Create Session session http://${CONTROLLER}:${RESTCONFPORT} auth=${AUTH} headers=${HEADERS_XML}
+ ${start_time}= Get Current Date
+ ${end_time}= Add Time To Date ${start_time} ${TEST_LENGTH}
+ ${end_time}= Convert Date ${end_time} epoch
+ Set Suite Variable ${end_time}
+
+Longevity Suite Teardown
+ [Documentation] Any cleanup neccessary to allow this test to be run in a static environment should go here
+ ... Currently, the same steps needed for the scalability suites should suffice.
