/**
	* Runs before all tests. Run this before each unit test in this class
	*
	*@throws Exception
	*@see {@link ActiveService}
	*/
	@Before	public void runBeforeAllTests() throws Exception {
		if (patientService == null) {
			patientService = Context.getPatientService();
			activeListService = Context.getActiveListService();
		}
		executeDataSet(ACTIVE_LIST_INITIAL_XML);
	}
