}
写好这些类之后，就可以开始着手测试了。
写一个测试CSV文件生成的jsp文件。如：

<%@ page contentType="text/html" import="com.vogoal.util.*,com.vogoal.util.csv.*,java.io.IOException" %>
create a csv file
<%
        try {
            CSVCreater csvCre = new CSVCreater("C:\\test.csv");
            csvCre.setConvertFlag(true);
            csvCre.setData("aaa");
            csvCre.setData("aa,a");
            csvCre.writeLine();
            csvCre.setData("aa\"a");
            csvCre.setData("aa,a");
            csvCre.setData("aa,a");
