At present, there are two common ways, jxl and POI. Because the more powerful POI, operational performance in the face of large amounts of data more than jxl, therefore, generally use POI at work to operate excel.
POI is an open-source library under Apache, POI provides a series of api for java programmers to provide read and write capabilities of Microsoft Office document formats.
The film will use
Example POI mode:
First of all tools, read and write Excel classes, Excelutil1
The following code, the code basically copied from the Internet, but debugging a bit, so that he can use:
package com.cailian.test.framework.utils;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;

Step use tools for testing:
the UI test automation, a value obtained on the page should be written in Excel, the need to obtain this value, then call the method setExcleFile1 write Excel on it.
When calling the method parameters are: file name, number of rows, number of columns, the value written, sheet single name.
Demand is: Excel to perform each of the embodiments, the need to write a value fixed by the columns in each row. For example, it is 30 in each row.
Line method can be used caseID, the column is fixed, the file name is written dead.
If the file name is also required to change, you can use the configuration file. The next article. . . . .
Step Three: When you run, you find that the value has been written in the document,
