1.导入依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency>
2.使用idea自动创建测试类,也可以自己手动创建

3.写测试类
@RunWith(SpringRunner.class)
@SpringBootTest
public class TestImpl2Test {
@Autowired
@Qualifier("testImpl2")
ITestServer iTestServer;
@Test
public void test(){
iTestServer.showClassName();
}
}
