從Selenium中的Excel文件中讀取數據Java

Question

我想從Excel表格中讀取數據以自動執行我的測試（使用許多登錄憑據）。我正在使用我在網上找到的實用程序。但它沒有成功運行。

這裏是實用

package google; 

    import java.io.File; 
    import java.io.IOException; 
    import java.util.Hashtable; 

    import jxl.Cell; 
    import jxl.Sheet; 
    import jxl.Workbook; 
    import jxl.read.biff.BiffException; 

    public class class2 { 

    static Sheet wrksheet; 
    static Workbook wrkbook =null; 
    static Hashtable dict= new Hashtable(); 
    //Create a Constructor 
    public class2(String ExcelSheetPath) throws BiffException, IOException 
    { 
    //Initialize 
    wrkbook = Workbook.getWorkbook(new File(ExcelSheetPath)); 
    //For Demo purpose the excel sheet path is hardcoded, but not recommended :) 
    wrksheet = wrkbook.getSheet("Sheet1"); 
    } 

    //Returns the Number of Rows 
    public static int RowCount() 
    { 
    return wrksheet.getRows(); 
    `enter code here` } 

    //Returns the Cell value by taking row and Column values as argument 
    public static String ReadCell(int column,int row) 
    { 
    return wrksheet.getCell(column,row).getContents(); 
    } 

    //Create Column Dictionary to hold all the Column Names 
    public static void ColumnDictionary() 
    {`enter code here` 
    //Iterate through all the columns in the Excel sheet and store the value  
    for(int col=0; col <= wrksheet.getColumns();col++) 
    { 
    dict.put(ReadCell(col,0), col); 
    } 
    } 

    //Read Column Names 
    public static int GetCell(String colName) 
    { 
    try { 
    int value; 
    value = ((Integer) dict.get(colName)).intValue(); 
    return value; 
    } catch (NullPointerException e) { 
    return (0); 

    } 
    } 

    } 

而下面是調用該實用程序類。

package google; 

import java.io.IOException; 

import jxl.read.biff.BiffException; 

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.ie.InternetExplorerDriver; 
import org.testng.annotations.BeforeTest; 
import org.testng.annotations.Test; 

import google.class2; 

public class class3 { 

//Global initialization of Variables 
static class2 xlsUtil; 
WebDriver driver = new InternetExplorerDriver(); 

//Constructor to initialze Excel for Data source 
public class3() throws BiffException, IOException 
{ 
//Let's assume we have only one Excel File which holds all Testcases. Demo !!! 
xlsUtil = new class2("C:/Users/admin/workspace/login.xls"); 
//Load the Excel Sheet Col in to Dictionary for Further use in our Test cases. 
xlsUtil.ColumnDictionary(); 
} 

@BeforeTest 
public void EnvironmentalSetup() 
{ 
    System.setProperty("webdriver.chrome.driver", 
"C:/Users/admin/Downloads/chromedriver.exe"); 
    WebDriver driver = new ChromeDriver(); 
    driver.get("http://192.168.1.20/dental/userlogin"); 
} 

@Test 

public void GmailLoginPage() throws InterruptedException { 

//Create a for loop.. for iterate through our Excel sheet for all the test cases. 
for(int rowCnt = 1;rowCnt <= xlsUtil.RowCount();rowCnt++) 
{ 

//Enter User Name by reading data from Excel 
WebElement userName = driver.findElement(By.name("UserName")); 
userName.clear(); 
userName.sendKeys(xlsUtil.ReadCell(xlsUtil.GetCell("EmailUserName"), rowCnt)); 

//Enter Password 
WebElement password = driver.findElement(By.name("Password")); 
password.clear(); 
password.sendKeys(xlsUtil.ReadCell(xlsUtil.GetCell("Emailpassword"), rowCnt)); 

//Click on the Sign In Button 
// WebElement signin = driver.findElement(By.name("signIn")); 
password.submit(); 

//Sleep for some time,so that we can see things in action @ Screen :) 
Thread.sleep(2000); 
} 
} 

} 

但是當我運行DIS中國社會科學院它說「不能實例google.class3 我沒有在這裏得到的錯誤。 請幫我成功運行這段代碼。

Answer 1

FileInputStream file = newFileInputStream(newFile("C:/Users/admin/workspace/login.xls")); 

    //Get the workbook instance for XLS file 
    HSSFWorkbook workbook = new HSSFWorkbook(file); 

    //Get first sheet from the workbook 
    HSSFSheet sheet = workbook.getSheetAt(0); 

    //Iterate through each rows from first sheet 
    Iterator<Row> rowIterator = sheet.iterator(); 

    while(rowIterator.hasNext()) { 

     Row row = rowIterator.next(); 

     //For each row, iterate through each columns 
     Iterator<Cell> cellIterator = row.cellIterator(); 
     while(cellIterator.hasNext()) {   

      Cell cell = cellIterator.next(); 
      if(cell.getColumnIndex() == 0){ 
        driver.findElement(By.name("UserName")).sendKeys(cell.getStringCellValue()); 
      } 
      else 
       driver.findElement(By.name("Password")).sendKeys(cell.getStringCellValue()); 
     }

    String userDir = System.getProperty("user.dir"); 
    filePath = userDir+"\\testdata\\Test_Data.xlsx"; 
    String data = null; 
    FileInputStream fis = new FileInputStream(filePath); 
    Workbook wb = WorkbookFactory.create(fis);

    for(int r=0 ; r<rowcount; r++){ 
     Row row = sh.getRow(r); 
     if(row.getCell(0).getStringCellValue().toLowerCase().equals(testID.toLowerCase())){ 
     int col = row.getLastCellNum();
