[英]Reading excel data in selenium with testNG
我是Selenium的新手,仍然在學習。 我試圖用兩個測試在TestNG中編寫一個程序,以從Excel讀取數據並使用Apache POI進行編寫。 我在同一文件夾中有一個XLS和一個XLSX文件,並嘗試使用這兩個文件。 我正在嘗試在testng.xml中配置Excel的路徑和名稱。 當我執行第一個測試以讀取數據時,工作表名稱被讀取為xml。 下面是我的testng.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="tests" thread-count="2">
<parameter name="filePath" value="C:\\Technologies\\Selenium\\WebDriver\\DataFiles\\ExcelFiles"></parameter>
<test name="Xlsx">
<parameter name="fileName" value="12142015_sx.xlsx"></parameter>
<parameter name="sheetName" value="xlsx_1"></parameter>
<classes>
<class name="handlefiles.handleExcel"/>
</classes>
</test>
<test name="Xls">
<parameter name="fileName" value="12142015_s.xls"></parameter>
<parameter name="sheetName" value="xls_1"></parameter>
<classes>
<class name="handlefiles.handleExcel"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
下面是Java類代碼。
package handlefiles;
import java.io.*;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.testng.annotations.*;
public class handleExcel {
@BeforeTest
@Parameters({"filePath", "fileName", "sheetName"})
public void readExcel(String filePath, String fileName, String sheetName) throws IOException{
// set the file path
File eFile = new File(filePath+"\\"+fileName);
//print the file path
System.out.println("File is at: "+eFile);
FileInputStream inputstream = new FileInputStream(eFile);
Workbook wb = null;
// Read and publish extension
String extensionName = fileName.substring(fileName.indexOf("."));
System.out.println("File type is: "+extensionName);
//Read the file
if(extensionName.equalsIgnoreCase(".xlsx")){
wb = new XSSFWorkbook(inputstream);
}else if(extensionName.equalsIgnoreCase(".xls")){
wb = new HSSFWorkbook(inputstream);
}
//Read the sheet name
Sheet wbSheet = wb.getSheet(sheetName);
System.out.println("Sheet Name is: "+wbSheet);
}
@Test(priority=1)
public void readData(Sheet wbSheet) {
// Get the row count
int rowCount = wbSheet.getLastRowNum() - wbSheet.getFirstRowNum();
// print data from excel
for (int i=0; i<rowCount-1; i++){
Row row = wbSheet.getRow(i);
for (int j=0; j<row.getLastCellNum(); j++){
System.out.println(row.getCell(j).getStringCellValue()+"||");
}
}
}
}
當我在Eclipse中運行時,我看到以下異常-
org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)

根據堆棧跟蹤,POI認為您正在嘗試使用POI的XLS代碼(不是XLSX代碼)打開XLSX文件。 也許文件擴展名錯誤,因為該文件是“ .xls”,但應該是“ .xlsx”,或者文件已損壞等。(或者您發現了錯誤)。
我建議改用POI的WorkbookFactory :
通過從提供的輸入中自動檢測,用於創建適當種類的工作簿(
HSSFWorkbook
或XSSFWorkbook
)的XSSFWorkbook
。
刪除以下IF條件,然后
if(extensionName.equalsIgnoreCase(".xlsx")){
wb = new XSSFWorkbook(inputstream);
}else if(extensionName.equalsIgnoreCase(".xls")){
wb = new HSSFWorkbook(inputstream);
}
添加這段代碼
wb = new XSSFWorkbook(inputstream);
我過去使用過,但從未告訴過我正在使用哪個擴展名。
