Question

以下是我在运行JUnit测试用例时遇到的错误。

在运行SV的JUnit测试用例作为代码时，我得到以下错误，即使所有SV都是代码罐。代码用于创建虚拟服务。如果我删除了行＆＃34; forGet（URL）......;＆＃34;测试用例会通过，否则会抛出错误。

以下是代码：

        String printResponse = gw.place("http://api.openweathermap.org/data/2.5/weather?q=London,uk&APPID=14c206d2c4fc6e04f152395f98fbfe20");
        System.out.println(printResponse);*/
        assertEquals(200, CUSTOM_STATUS_CODE);
      }
    }

请建议。

其中一个SV jar，依赖于JDK1.8 jar（tools.jar），因此我们需要在项目的buildpath中添加JDK1.8库。
