spring boot 单元测试
单元测试,在开发中用于测试我们方法或服务的正确性,一般写在工程test包下。 @RunWith(SpringRunner.class) @SpringBootTest(classes = Application.class) //表示为spring boot测试 public class AtrributeDataMapperTest { private static final Logger logger = LogManager.getLogger(AtrributeDataMapperTest.class); @Autowired private AtrributeDataMapper mappper; //注入需要测试的类 @Test public void testGetColumnValues_Level3_Cable() { Integer instanceId = 2230; String tableName = "t_cable"; Integer level = 3; String field = "Length"; List<Object> data = mappper.getColumnValues(instanceId, tableName, level, field); data.forEach(System.out::println); } } 注意:@SpringBootTest的classes属性指定springboot的启动类的class,如这里的Application.class 如果不加classes属性,那么当前测试类必须在启动类所在的包或其子包中。否则运行时异常
