java - 模拟响应不起作用，并调用真正的方法

Question

我正在使用mockito，我正在尝试从我的服务测试一个get方法，问题是测试正在调用真正的方法，因此它根本不起作用。接下来是我想测试的方法:

     public Hours getHours(String id) throws IllegalArgumentException {
        logger.debug("getting id {}", id);
        try {
          return repository.get(validateUuid(id).toString());
        } catch (Exception e) {
          logger.error("there was an issue querying with id {}", id, e);
          publishError("get", e);
          throw new IllegalArgumentException(
              String.format("there was an issue querying with id {%s}", id));
        }
    }

    private UUID validateUuid(String id) {
        try {
          return UUID.fromString(id);
        } catch (Exception e) {
          throw new IllegalArgumentException("the id given was was invalid", e);
        }
    }

这是我的测试代码:

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import java.util.ArrayList;
import java.util.List;
import java.util.UUID;

import static org.junit.jupiter.api.Assertions.assertArrayEquals;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.mockito.BDDMockito.given;
import static org.mockito.Matchers.*;
import static org.mockito.Mockito.when;

class serviceTest {

    @Mock
    private Repository<Hours> repository;
    private Service service;

    @BeforeEach
    public void init() {
        MockitoAnnotations.initMocks(this);
        service = new service();
    }

    @Test
    void addHours() {
        Hours hours = new Hours();
        hours.setCorrelationId("a-988787888b712ijj-0997878");
        hours.setPerner("720022");

        given(repository.post(any(Hours.class), anyBoolean())).willReturn(hours);

        Hours persistedHours = service.addHours(hours);

        assertEquals(persistedHours, hours);
    }

    @Test
    void getHours() {
        String mockedUUID = UUID.randomUUID().toString();
        Hours hours = new Hours();
        Hours.setCorrelationId("a-988787888b712ijj-0997878");

        when(repository.get(mockedUUID)).thenReturn(hours);

        Hours persistedHours = service.getHours(mockedUUID);

        assertEquals(persistedHours.getCorrelationId(), hours.getCorrelationId());
    }

    @Test
    void getHousrAll() {
        List<Hours> hoursList  = new ArrayList<>();
        PaginatedResult<Hours> result = new PaginatedResult<>();
        result.setResult(hoursList);

        given(repository.get(any(Query.class))).willReturn(result);

        PaginatedResult<Hours> result2 = service.getHousrAll(new Query());

        assertEquals(result , result2);
    }
}

我还使用过:

given(banquetLaborHoursRepository.get(anyString())).willReturn(banquetLabourHours);

但是结果是一样的。有什么想法吗？

这可以帮助你。通常，当您进行测试时，您会将依赖项设置为模拟对象。这里的存储库是 YourService 的依赖项。 @InjectsMock 基本上是将存储库模拟对象设置到您的服务中。

但是如果您不想使用注释，您需要创建一个服务的模拟对象和存储库的模拟对象，并将其设置为服务模拟对象。这也可以工作，但是像 InjectsMock 这样的注释可以减少我们的代码。

 @RunWith(MockitoJUnitRunner.class)
    class GameTester {

    @InjectMocks
    YourService service;
    @Mock
    Repository repository;

    @Test
        void getHours() {
            Hours hours = new Hours();
            hours.setCorrelationId("a-988787888b712ijj-0997878");
            when(repository.get(mockedUUID)).thenReturn(hours);

            Hours persistedBanquet = service.getHours("a-988787888b712ijj-0997878");
            assertEquals(persistedBanquet.getCorrelationId(), hours.getCorrelationId());
        }
}
