Question

我有一个Spring-boot应用程序，正在尝试为其创建单元测试用例。以下是我要运行的代码，我没有任何配置文件（仅用于注释），因此加载所有配置的主要类为ElastSearchBootApplication类。由于某种原因，我看到以下错误。

@ComponentScan(basePackages = "com.somename")
@SpringBootApplication
@EnableScheduling
public class ElastSearchBootApplication {

    private static final Logger LOG = LoggerFactory.getLogger(ElastSearchBootApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(ElastSearchBootApplication.class, args);
    }

    @Autowired
    private ElastSearchLogLevel logsSearch;

    @Scheduled(fixedRate = 120000)
public void scheduledSearchLogs() {
        ...

测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = ElastSearchBootApplication.class)
public class LogSearchTest {

    @Mock
    private RestHighLevelClient client;
    @Mock
      private ExecutorService ALERT_POOL;

    @Before
    public void setUp() throws Exception {
          client = mock(RestHighLevelClient.class);
        ALERT_POOL = mock(ExecutorService.class);

        try {
            when(client.search(anyObject())).thenReturn(getResponse());
        } catch (Exception e) {
            // I see NullPointerException but both the instances are available here
            e.printStackTrace();
        }
        doNothing().when(ALERT_POOL.invokeAll(anyObject()));
    }

当尝试运行spring-boot测试时，我看到以下错误：

org.springframework.boot.test.context.SpringBootTestContextBootstrapper buildDefaultMergedContextConfiguration
INFO: Neither @ContextConfiguration nor @ContextHierarchy found for test class [com.somename.search.LogSearchTest], using SpringBootContextLoader
org.springframework.test.context.support.AbstractContextLoader generateDefaultLocations
INFO: Could not detect default resource locations for test class [com.somename.search.LogSearchTest]: no resource found for suffixes {-context.xml, Context.groovy}.
org.springframework.test.context.support.AnnotationConfigContextLoaderUtils detectDefaultConfigurationClasses
INFO: Could not detect default configuration classes for test class [com.somename.search.LogSearchTest]: LogSearchTest does not declare any static, non-private, non-final, nested classes annotated with @Configuration.

我看到@SpringBootTest用于集成测试，因此我可以将其用于单元测试吗？如果删除它，则会得到另一组看上去类似的异常。我将对在没有SpringBootTest
为什么我的测试用例说缺少某些配置。在线样本讨论了我没有的xml文件。那我在这里想念什么？
我可以从fixedRate动态传递Environment的值，并像@Scheduled(fixedRate = ${some.value.defined})那样放置它吗？

更新

我可以运行测试，但没有正确的顺序。理想情况下，我希望setUp首先运行。但其运行第二。此外，行when(client.search(anyObject())).thenReturn(getResponse());失败了，我不知道原因...

Answer 1

您必须在测试类中添加@ContextConfiguration注释以指定配置文件。

@ContextConfiguration(classes = ElastSearchBootApplication.class)

Answer 2

尝试一下：

@RunWith(SpringRunner.class)
@SpringBootTest
public class LogSearchTest {

  @MockBean
  private RestHighLevelClient client;
  @MockBean
  private ExecutorService ALERT_POOL;

  @Before
  public void setUp() throws Exception {
   try {
        when(client.search(anyObject())).thenReturn(getResponse());
    } catch (Exception e) {
        // I see NullPointerException but both the instances are available here
        e.printStackTrace();
    }
    doNothing().when(ALERT_POOL.invokeAll(anyObject()));
  }

SpringRunner无法检测到配置
