在Selenium Java中从Excel文件读取数据
我正在尝试从Excel工作表中读取数据以自动执行我的testing（使用许多login凭证）。 我正在使用我在网上find的实用程序。 但它没有成功运行。
这是实用程序
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); } } } 以下是调用此实用程序的类。
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，当我运行dis cass它说'不能实例化google.class3我不明白这里。 请帮助我成功运行此代码。
