Dev Onboarding - adding test to JMeter test suite

Getting up to speed on the code base by running Jmeter tests locally and adding an additional functional test (and additional assertion to existing test) in the Validation suite.  Additional test was to perform an XML well formed check.  Additional assertion was to validate the error message on the required header missing test.

NOTE: I noticed that my jmeter updated the properties version to 2.3.  Is there a way to easily execute my branch from jenkins to ensure my jmeter didn't do something that'll fail to run in earlier versions?
