Sorry about comments! Is that the corrrect uuid?

	public void shouldPurgeAConceptSource() throws Exception {
		String uuid = "97097dd9-b092-4b68-a2dc-e5e5be961d42";
		//Assert.assertNotNull(service.getConceptSourceByUuid(getUuid()));
		Assert.assertNotNull(service.getConceptSourceByUuid(uuid));
		// MockHttpServletRequest req = request(RequestMethod.DELETE, getURI() + "/" + getUuid());
		MockHttpServletRequest req = request(RequestMethod.DELETE, getURI() + "/" + uuid);
		req.addParameter("purge", "");
		handle(req);
		// Assert.assertNull(service.getConceptSourceByUuid(getUuid()));
		Assert.assertNotNull(service.getConceptSourceByUuid(uuid));
	}
