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;

 */
@RunWith(MockitoJUnitRunner.class)
public class FileIOBizTest {

    @InjectMocks
    FileIOBiz fileIOBiz;

    @Mock
    FileIOClient fileIOClient;

    @Test
    public void getFile() {
//        Mock阶段
//        构造参数
        FileRequest request = new FileRequest();
        request.setName("Title");
//        Mock Client
        when(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 {

        @Autowired
        private ISystemInfoService systemInfoservice;

        @Test
        public void add() throws Exception {
        }

        @Test
         public void findAll() throws Exception {
         }

}
