无法让 Quarkus/Mockito 使用 @InjectMock 实例 - 从端点测试返回错误数据

Question

我有一个非常简单的 Quarkus REST 应用程序，可以读取/写入 Redis。在编写端点测试时（使用 Quarkus 模拟指南），但我无法从模拟返回数据。相反，它看起来像是使用非模拟注入并返回非空和空列表。

这是依赖顺序。我想嘲笑

RedisService

:

DataEndpointResource

->

DataService

->

RedisService

DataEndpointResource

：

@Path("/data")
@RequestScoped
public class DataEndpointResource {

    @Inject
    DataService service;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getAllValues() {

        Collection<DataRecord> values;
        try {
            values = service.getAllValues();
        } catch (RedisException ex) {
            return Response.serverError().build();
        }

        return Response.ok(values).build();

    }
}

DataService

：

@RequestScoped
public class DataService {
    
    @Inject
    private RedisService redisService;

    public Collection<DataRecord> getAllValues() throws RedisException {
        
        return this.redisService.getAllValues();
        
    }
}

RedisService

：

@ApplicationScoped
public class RedisService {
    
    ReactiveRedisDataSource ds;
    
    KeyCommands<String> keyCommands;
    ValueCommands<String, ObjectLockRecord> valueCommands;
    
    public RedisService(RedisDataSource ds) {
        
        keyCommands = ds.key();
        valueCommands = ds.value(ObjectLockRecord.class);
        
    }
    
    public Collection<DataRecord> getAllValues() throws RedisException {
        try {
            // do redis stuff and return values
        } catch (Exception ex) {
            log("Error obtaining values", ex);
            throw new RedisException(ex);
        }
    }
}

测试：

@QuarkusIntegrationTest
public class DataEndpointResourceIT extends DataEndpointResourceTest {
    
}

@QuarkusTest
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
@DisplayName("Data REST Resource")
public class DataEndpointResourceTest {

    @InjectMock
    RedisService redisServiceMock;

    Map<String, DataRecord> locks;

    @BeforeEach
    public void setUp() throws RedisException {

        locks = new HashMap<>();

        DataRecord r = new DataRecord("1234", "data1");
        locks.put(r.getKey(), r);
        r = DataRecord r = new DataRecord("asdf", "data2");
        locks.put(r.getKey(), r);

    }

    @Test
    @Order(1)
    @DisplayName("Endpoint: GET /data")
    public void getData() throws RedisException // without throws it complains {        

        when(redisServiceMock.getAllValues()).thenReturn(new ArrayList<>(locks.keySet()));

        List<DataRecord> list = given()
                .accept(ContentType.JSON)
                .when()
                .get("/api/v1/data")
                .then()
                .statusCode(200)
                .extract().body().as(new TypeRef<>() {
                });

        Assertions.assertNotNull(list);
        Assertions.assertEquals(2, list.size());

    }

}

总是失败：

如果您只运行 Quarkus 测试

DataEndpointResourceTest

，模拟应该可以工作。您不能将 Bean 注入

@QuarkusIntegrationTest

中。不会有任何影响。

Quarkus 文档描述了如何编写 Quarkus 集成测试：https://quarkus.io/guides/getting-started-testing#quarkus-integration-test
