SpringRunner 无法检测配置

Question

我有一个 spring-boot 应用程序，我正在尝试为其创建单元测试用例。下面是我尝试运行的代码，我没有任何配置文件(仅使用注释)所以加载所有配置的主类是 ElastSearchBootApplication类(class)。出于某种原因，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()));
    }

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.

我看到了 @SpringBootTest用于集成测试，那么我可以将它用于单元测试吗？如果我删除它，那么我会得到另一组看起来相似的异常。如果没有 SpringBootTest，我会对运行这个测试用例更感兴趣。

为什么我的测试用例说缺少某些配置。在线示例讨论了我没有的 xml 文件。那么我在这里错过了什么？

我可以动态传递 fixedRate 的值吗？来自 Environment并把它像 @Scheduled(fixedRate = ${some.value.defined})

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先运行。但它的运行第二。也行 when(client.search(anyObject())).thenReturn(getResponse());失败了，我不明白原因......

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

@ContextConfiguration(classes = ElastSearchBootApplication.class)
