请帮忙。
我已经解决了我的问题,谢谢你的帮助。。我只是排除了PieChart.class,因为每当我运行junit时,因为PieChart.class是一个实用类,所以不能在ant中运行。。在xml上,我只是排除了类,
,只是为了确保添加了

ABMTSuite是什么样子的?这些代码来自selenium,我添加了一个条件,只是为了跟踪测试用例是否失败/通过,顺便说一句,忽略@test中的代码,我只是使用selenium记录,这只会出现在google站点上,然后键入一个搜索关键字,就这样。正如您所看到的,我强制在if-else条件下通过了这个测试——这只是一个测试,在这里它将调用PieChart.class来生成一个饼图,并将其保存到指定的位置。希望我能回答你的问题。对不起,我的英语不好。如果您执行ABMTSuite,请显示套件的代码。或者将ant改为使用ABMTLinks。我没有套件,在eclipse中我只运行代码ABMTLinks by(run>junittest)并工作。在ant上时,例如我的类文件夹:C:/workspace/ABMT Test/:然后我在命令提示符下键入ant命令。。e、 g C:/workspace/ABTM Test/:ant clean C:/workspace/ABTM Test/:ant compile C:/workspace/ABTM Test/:ant run如果您有套件,请查看ant文件中的junit任务!
