Question

我在运行测试用例时遇到异常。请帮忙。

代码：

       @Test
       public void shouldSaveTypedOrder() throws Exception {
           mockControl.replay();
           sampleDto.setId(null);
           Sample savedDto = sampleDao.save(sampleDto);
           mockControl.verify();
           assertThat(savedDto).isEqualTo(sampleDto);
       }

错误：

您的DAO尝试在第121行的BaseDaoImpl的insert方法中获取与DataSource的连接。

 com.inetwork.common.dao.BaseDaoImpl.insert(BaseDaoImpl.java:121)

您可能不想连接到真实的数据库。

您还需要以某种方式模拟Connection对象并让DataSource.getConnection（）方法返回您的模拟。
