几个重要的注解
怎么用mockito写单元测试？

package Biz;import Client.FileIOClient;
import Req.FileRequest;
import Res.FileResponse;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;import static org.mockito.ArgumentMatchers.any;
import static org.mockito.Mockito.when;/*** @Author:TieJiang* @Date: 2021/1/19 8:44 下午* 人一能之，己十之，人十能之，己百之，果能此道矣，虽愚必明，虽柔必强。*/
@RunWith(MockitoJUnitRunner.class)
public class FileIOBizTest {@InjectMocksFileIOBiz fileIOBiz;@MockFileIOClient fileIOClient;@Testpublic void getFile() {
//        Mock阶段
//        构造参数FileRequest request = new FileRequest();request.setName("Title");
//        Mock Clientwhen(fileIOClient.FileRead(any())).thenReturn(5);when(fileIOClient.FileWrite(any())).thenReturn(5);//        Mock结果，进行校验：结果一定是根据现有逻辑能判断出来的FileResponse response = fileIOBiz.GetFile(request);Assert.assertNotNull(response);Assert.assertEquals(response.getValue(),"5 5");}
}

怎么写SpringRunner的单元测试？

@RunWith(SpringRunner.class) //14.版本之前用的是SpringJUnit4ClassRunner.class
@SpringBootTest(classes = Application.class) //1.4版本之前用的是//@SpringApplicationConfiguration(classes = Application.class)
public class SystemInfoServiceImplTest {@Autowiredprivate ISystemInfoService systemInfoservice;@Testpublic void add() throws Exception {}@Testpublic void findAll() throws Exception {}}
