【问题描述】：
每当我在 Ant 中运行代码时都会出错，但在 Eclipse 上使用 (Run > JunitTest) 运行良好且没有错误。
以下是我生成报告时收到的错误消息：
“测试类应该只有一个公共零参数构造函数”
java.lang.Exception: 测试类应该只有一个公共 零参数构造函数 java.lang.reflect.Constructor.newInstance(Unknown Source)
“没有可运行的方法” -java.lang.Exception：java.lang.reflect.Constructor.newInstance（未知来源）中没有可运行的方法
请看我的代码：
这段代码有注释（@）

if (iTotalTestCaseCtr == iSum) {

请帮忙。
【问题讨论】：
-
ABMTSuite 长什么样子？
-
该代码来自 selenium，我添加了一个条件来跟踪测试用例是否失败/通过，顺便说一句，只需忽略 @Test 中的代码，我只是使用 selenium 记录，即只在谷歌网站上然后输入搜索关键字就可以了。如您所见，我强制在 if-else 条件下通过此测试 - 只是一个测试，在这里它将调用 PieChart.class 生成饼图并将其保存到指定位置。希望我回答你的问题。对不起我的英语。
-
在您执行 ABMTSuite 的 ant 中，请显示该套件的代码。或者更改 ant 以使用 ABMTLinks。
-
我没有套件，在 Eclipse 中我只运行我的代码 ABMTLinks（运行 > Junit 测试）并且可以工作。在 ant 上，例如我的类文件夹：C:/workspace/ABMT-Test/: 然后从这里我只需在命令提示符中键入 ant 命令.. 例如 C:/workspace/ABTM-Test/: ant clean C:/workspace/ ABTM-Test/: ant compile C:/workspace/ABTM-Test/: ant run
-
你有套件，看看你的ant文件中的junit任务！
