Question

每当我在Ant中运行我的代码时都会出现错误，但是在使用（运行＆gt; JunitTest）的eclipse上它运行良好而没有错误。

下面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public   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

请查看我的代码：

此代码包含注释（@）

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是一个实用程序类，所以它不能在ant中运行。在xml上我只是排除了类<exclude name = "PieChart.class" />，只是为了确保我刚刚添加了<exclude name="PieChart.java" />

                <classpath refid="Igloo.path" />
                <batchtest todir="${Igloo.reportsDir}" fork="true">
                    <fileset dir="${Igloo.dest}">
                        <include name="ABMTLinks.class" />
                        <exclude name = "PieChart.class" />
                        <exclude name = "PieChart.java" />
                    </fileset>
                </batchtest>
            <formatter type="xml" />
            <classpath refid="Igloo.path" />
            </junit>

                <junitreport todir="${Igloo.reportsDir}">
                    <fileset dir="${Igloo.reportsDir}">
                        <include name="TEST-*.xml" />
                    </fileset>
                    <report todir="${Igloo.reportsDir}"/>       
                </junitreport>
        </target>

No Runnable方法和Test类应该只有一个公共零参数构造函数
