java - 没有 Runnable 方法和 Test 类应该只有一个公共(public)零参数构造函数

Question

每当我在 Ant 中运行我的代码时，我都会遇到错误，但在使用 (Run > JunitTest) 的 eclipse 上它运行良好，没有错误。

以下是我在生成报告时收到的错误消息:

"Test class should have exactly one public zero-argument constructor"

java.lang.Exception: Test class should have exactly one public zero-argument constructor at java.lang.reflect.Constructor.newInstance(Unknown Source)

"No Runnable methods" -java.lang.Exception: No runnable methods at java.lang.reflect.Constructor.newInstance(Unknown Source)

请看我的代码:

这段代码有注释(@)

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 是一个实用程序类，所以它不能在 ant 中运行。在 xml 上我只是排除类，<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>
