我正在使用挂毯开发 Web 应用程序。我正在使用 junit 测试套件测试我的应用程序，并使用 ant build 生成战争文件和 html 报告。在我的 html 报告文件中，我有以下警告。
Multiple annotations found at this line:
- Attribute (width) is obsolete. Its use is discouraged in HTML5 documents.
- Attribute (cellpadding) is obsolete. Its use is discouraged in HTML5
documents.
- Undefined attribute value (0).
- Attribute (language) is obsolete. Its use is discouraged in HTML5 documents.
以下是我的测试和报告生成代码。
<target name="test" depends="compile" description="Running Test Suite">
<mkdir dir="${target.data.dir}"/>
<mkdir dir="${target.htmlreports.dir}"/>
<junit fork="no" haltonfailure="no" showoutput="yes" printsummary="true" >
<test name="${junit.class.name}" todir="${target.data.dir}"/>
<formatter type="brief" usefile="false"/>
<classpath refid="classpath.test"/>
<sysproperty key="ant.home" value="${ant.home}"/>
<formatter type="xml"/>
</junit>
<junitreport todir="${target.htmlreports.dir}">
<fileset dir="${target.data.dir}">
<include name="TEST-*.xml"/>
</fileset>
<report format="frames" todir="${target.htmlreports.dir}"/>
</junitreport>
</target>
这是我的 html 报告文件之一。
