I a trying to mock restetmplate but don't why I am getting the below error. I am using doreturn to verify the invocation of the resttemplate.Is there by other way to mock the rest template and mock the HTTP request
class ToTest{
public ResponseEntity<String> getValue(){
if (StringUtils.isNotEmpty(token)) {
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", "Bearer " + token);
headers.setContentType(MediaType.APPLICATION_JSON);
UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(etsServiceResourceDetails.getAccessTokenUri())
.queryParam("test","tsetValue");
builder.queryParam("some","someValue");
HttpEntity<?> entity = new HttpEntity<>(headers);
try {
response = restTemplate.exchange(builder.toUriString(), HttpMethod.GET, entity, String.class);
}
catch (RestClientResponseException ex ) {
log.error(ex);
if ( ex.getRawStatusCode() == HttpStatus.NOT_FOUND.value()) {
return ResponseEntity.notFound().build();
}
}
}
}
}
Unit Test for the rest Temaplate
@Test
public void testExchange() {
String token="abbjabxkcbkscksckbckbkcbksckckkcb";
MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<>();
queryParams.add("query", "star");
queryParams.add("test", "star2");
UriComponents uriComponents = UriComponentsBuilder.newInstance().scheme("http").host("localhost:8080/some/add").path("/").queryParams(queryParams).buildAndExpand();
RestTemplate r = new RestTemplate();
RestTemplate r1 = spy(r);
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", "Bearer " + token);
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<?> entity = new HttpEntity<>(headers);
// ResponseEntity responserm= //r1.exchange(uriComponents.toUriString(),HttpMethod.GET,entity,String.class); //I am getting error org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8080 doReturn(new ResponseEntity("", HttpStatus.OK)).when(r1).exchange(anyString(), any(HttpMethod.class), any(HttpEntity.class), any(Class.class));
verify(r1, times(1)).exchange(eq(uriComponents.toUriString()), any(), any(), eq(String.class));
assertEquals("check", "http://localhost:8080/some/add/?query=s1&test=s2", uriComponents.toUriString());
}

Actually, there were zero interactions with this mock.
Wanted but not invoked:
