Problem mocking restTemplate

[Gowher Naik]

Hi, I am using EasyMock for mocking and i am having problem while mocking restTemplate . My class calls "exchange" method of restTemplate which returns responseEntity<String> . Here is the method i want to test. Whenever i run the junit for this , it retuns an error message saying 7 methods expected and 5 recorded. I am using Spring 3.0.2

HttpHeaders httpHeaders = new HttpHeaders();
		httpHeaders.setContentType(MediaType.APPLICATION_XML);
		HttpEntity<String> entity = new HttpEntity<String>(httpHeaders);
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, entity,
				String.class, apiversion, clientid, productid, campaignCode);
		this.setException(this.getHeaderMap(response).get("x-capi-error-code"));

		JAXBContext context = JAXBContext
				.newInstance(ResponseVO.class);
		Unmarshaller unmarshaller = context.createUnmarshaller();
		ProductEnquiryResponseVO xmlResponse = (ResponseVO) unmarshaller
				.unmarshal(new StringReader(response.getBody()));
		return xmlResponse;

please suggest any solution to write a junit for this method.
