MockRestServiceServer.verify不适用于使用Unirest库的服务

问题描述

我正在尝试为调用第三方API的服务编写测试用例。我的服务代码如下：

public List<FoodTruckDto> listFoodTruckLocations(Double givenLatitude,Double givenLongitude) throws Exception{
        
        log.info("Given Latitude => "+givenLatitude+" Given Longitude => "+givenLongitude);

        List<FoodTruckDto> foodTrucks = new ArrayList<>();

        HttpResponse<List<FoodTruckDto>> foodTrucksResponse = Unirest.get(locationUrl)
                .queryString("facilitytype","Truck")
                .asObject(new GenericType<List<FoodTruckDto>>(){});

        if (foodTrucksResponse.getStatus() == HttpStatus.OK) {
            
            foodTrucks = foodTrucksResponse.getBody();          
            
            foodTrucks.sort(new SortingLocations(givenLatitude,givenLongitude));           
            
        } else {
            UnirestParsingException ex = foodTrucksResponse.getParsingError().get();
            log.error("Error Message => "+ex.getMessage());
            log.error("Error Cause => "+ex.getCause());
            log.error("Error Original Body => "+ex.getoriginalBody());          
            throw new CustomException("exc001");
        }       

        return foodTrucks;

    }

服务方法的测试代码如下，该代码使用RestTemplate和MockRestServiceServer：

@SpringBoottest
public class LocationServiceImpltest {

    @Mock
    private RestTemplate restTemplate;

    private MockRestServiceServer mockServer;

    @MockBean
    private LocationService locationService;

    @BeforeEach
    public void setUp() {

        mockServer = MockRestServiceServer.createServer(restTemplate);

    }    
    
    @Test
    public void testListFoodTruckLocations() throws Exception {

        Gson gson = new Gson();

        List<FoodTruckDto> foodTruckResult = new ArrayList<>();

        this.mockServer.expect(ExpectedCount.once(),requestTo("https://data.sfgov.org/resource/rqzj-sfat.json?facilitytype=Truck"))
        .andExpect(method(HttpMethod.GET)).andRespond(withStatus(HttpStatus.OK).contentType(MediaType.APPLICATION_JSON).body(gson.toJson(foodTruckResult)));                         

        List<FoodTruckDto> foodTruckDtos = locationService.listFoodTruckLocations(233.3,-131.02);

        mockServer.verify();    

        assertthat(foodTruckDtos).isEqualTo(foodTruckResult);
    }

}

测试代码在mockServer.verify()处失败。这与Unirest和RestTemplate有什么关系吗？不能使用RestTemplate测试使用Unirest的服务？
