                </executions>
            </plugin>

        

2.Mockito测试类编写

import static org.mockito.Mockito.*;
// ... 导入必要的包

@RunWith(MockitoJUnitRunner.class)
public class CalculatorServiceTest {

    @Mock
    private CalculatorService calculatorService;
    
    @Test
    public void shouldReturnExpectedResultWhenAddTwoNumbers() {
        // 给定条件 - 设置期望行为
        when(calculatorService.add(10, 20)).thenReturn(30);
        // 执行动作
        calculatorService.add(10, 20);
    }
}

2.Mybatis-Plus相关方法mock

1.xxxService.lambadQuery().list

// 源代码
List<SysUserInfo> sysUserInfo  = sysUserInfoService.lambdaQuery().eq(SysUserInfo::getEmployeeName,"1111").list();
// mock后的代码
List<SysUserInfo> list = new ArrayList<>();
LambdaQueryChainWrapper<SysUserInfo> sysUserMapper = new LambdaQueryChainWrapper<>(mock(SysUserInfoMapper.class)); 
when(mockActivityService.lambdaQuery()).thenReturn(sysUserMapper);
when(sysUserMapper.list()).thenReturn(list);

2.调用私有方法

1.SysUserTokenCachedServiceImpl

@Service
public class SysUserTokenCachedServiceImpl implements SysUserTokenCachedService {


    private Boolean setSysUserToken(SysUserTokenEntity sysUserTokenEntity) {
        return Boolean.TRUE;
    }
}

2.反射SysUserTokenCachedServiceImpl 中的私有方法

    @Test
    @SneakyThrows
    void test_private_method() {
        SysUserTokenCachedServiceImpl service = new SysUserTokenCachedServiceImpl();
        //String.class表示参数的类型,有几个参数就写几个
        Method method = SysUserTokenCachedServiceImpl.class.getDeclaredMethod("setSysUserToken", SysUserTokenEntity.class);
        method.setAccessible(true);
        SysUserTokenEntity sysUserTokenEntity = new SysUserTokenEntity();
        method.invoke(service, sysUserTokenEntity);
    }

3.启动maven-test 生成jacoco覆盖率文件

4.Jacoco源码覆盖标记

红色:这一行没有分支被执行
黄色:这一行只有部分分支被执行
绿色:这一行被分支执行了
