我有一个spring引导应用程序，它试图创建单元测试用例。下面是我试图运行的代码，我没有任何配置文件(只使用注释)，所以加载所有配置的主类是ElastSearchBootApplication类。由于某种原因，我看到了下面的错误。

@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() {
        ...

考试班：

@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()));
    }

在尝试运行spring启动测试时，我看到了以下错误：

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，所以我可以将它用于单元测试吗？如果删除它，则会得到另一组类似的异常。如果不使用SpringBootTest，我会更感兴趣地运行这个测试案例。
为什么我的测试用例说缺少一些配置。在线上的示例讨论了我没有的xml文件。我在这里错过了什么？
我是否可以从fixedRate动态传递Environment的值，并将其放在@Scheduled(fixedRate = ${some.value.defined})中

更新

我可以运行测试，但没有适当的命令。理想情况下，我希望setUp首先运行。但它的运行第二。另外，when(client.search(anyObject())).thenReturn(getResponse());的线路失败了，我不明白原因.

spring

spring-boot

spring-test

您必须将注释@ContextConfiguration添加到您的测试类中，以指定配置文件。

@ContextConfiguration(classes = ElastSearchBootApplication.class)

试试这个：

@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()));
  }
