Mockito.When 方法在调用方法时无法 return 模拟对象

Question

我看到很多关于这个问题的帖子，但仍然无法解决我的问题。

when(queryEngineService.getRelationshipWithResources(anyString(), refEq(filterDto), anyString(), anyString(),
                anyInt(), anyInt(), anyString())).thenReturn(tenantResponseDto);
TenantResponseDto dto = queryEngineService.getRelationshipWithResources(anyString(), refEq(filterDto),
                anyString(), anyString(), anyInt(), anyInt(), anyString());

当我调试对象时。我看不到其中的模拟数据。有什么我想念的吗？

下面是我的测试类：

    public class QueryEngineAPITest extends AbstractTest {

    QueryEngineService queryEngineService = Mockito.mock(QueryEngineService.class);
    TenantResponseDto tenantResponseDto;

    private QueryEngineDto queryEngineDto;
    private RelationshipFilterDto filterDto;
    @Before
    public void setUp() throws Exception {
        super.setUp();
        prepareMockData();

    }

    void prepareMockData() {
        tenantResponseDto = new TenantResponseDto();
        int i = 0;
        queryEngineDto = new QueryEngineDto();
        List<Map<String, Object>> mockDataList = new ArrayList<Map<String, Object>>();
        while (i < 10) {
            Map<String, Object> mockDataMap = new HashMap<String, Object>();
            mockDataMap.put("APPLICATION", "AWS");
            mockDataMap.put("ENVIRONMENT_NAME", "SIGMA LABS" + i);
            mockDataList.add(mockDataMap);
            i++;
        }
        queryEngineDto.setQueryData(mockDataList);
        tenantResponseDto.setResponseAsQueryEngineDto(queryEngineDto);
tenantResponseDto.setResponseCount(Long.valueOf(queryEngineDto.getQueryData().size()));

    filterDto = new RelationshipFilterDto();
    filterDto.setBefore("");
}

@Test
public void getRelationShipsTest() throws Exception {
    when(queryEngineService.getRelationshipWithResources(eq(""), refEq(filterDto), eq(""), eq(""), eq(1), eq(1),
            eq(""))).thenReturn(tenantResponseDto);
    TenantResponseDto dto = queryEngineService.getRelationshipWithResources(eq(""), refEq(filterDto), eq(""),
            eq(""), eq(1), eq(1), eq(""));
    assertFalse(dto.getResponseAsQueryEngineDto().getQueryData().isEmpty());
    assertEquals(Long.valueOf(dto.getResponseAsQueryEngineDto().getQueryData().size()), Long.valueOf(10));

}

你的带有参数的模拟方法与你调用的方法不匹配

when(queryEngineService.getRelationshipWithResources(eq(""), refEq(filterDto), eq(""), eq(""), eq(1), eq(1),eq(""))).thenReturn(tenantResponseDto);
TenantResponseDto dto = queryEngineService.getRelationshipWithResources(eq(""), refEq(filterDto), eq(""),
                eq(""), eq(1), eq(1), eq(""));

您需要将第二行更改为：

TenantResponseDto dto = queryEngineService.getRelationshipWithResources("",filterDto, "", "", 1, 1, "");

eq 和 refEq 称为参数匹配器，当您想运行测试时，您需要按原样提供参数，而不是在参数匹配器中
