org.openqa.selenium.NoSuchElementException

Question

我正在尝试使用xsl表导入登录凭据，如：username和password，使用下面的代码，但运行时出现NoSuchElementException异常，

我的xsl表格如下：

  username    |  password

我正在使用：

• 蚀
• webdriver.iostream
• selenium tool

Login.java：

package Iostream;

import java.io.FileInputStream;

import jxl.Sheet;
import jxl.Workbook;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;

public class Login {

  public WebDriver driver;

  @Test
  public void f()throws Exception {
      FileInputStream fi=new FileInputStream("E:\\workspace1\\SeleniumAutomation\\test data\\login.xls");
      Workbook w= Workbook.getWorkbook(fi);
      Sheet s=w.getSheet(0);
      driver.findElement(By.id("f_id")).sendKeys(s.getCell(0,1).getContents());
      driver.findElement(By.id("f_pwd")).sendKeys(s.getCell(1,0).getContents());
      Thread.sleep(5000);
      driver.findElement(By.linkText("input.signin")).click();
      Thread.sleep(3000);
  }

  @BeforeTest
  public void beforeTest() {
      System.setProperty("webdriver.chrome.driver","\\E:\\lib\\chromedriver.exe");
      driver=new ChromeDriver();
      driver.get("http://www.gmail.com");
  }

  @AfterTest
  public void afterTest() {
  }
}

例外是：

Driver info: org.openqa.selenium.chrome.ChromeDriver

问题出在哪里？

Answer 1

您遇到了这个问题，因为当您get("http://gmail.com/")时，"f_id"和"f_pwd"不在那里。

如果您打算登录，那么您应该更具体地使用您的网址，并且您应该使用以下代码：

  @Test
  public void f()throws Exception {
      FileInputStream fi=new FileInputStream("E:\\workspace1\\SeleniumAutomation\\test data\\login.xls");
      Workbook w= Workbook.getWorkbook(fi);
      Sheet s=w.getSheet(0);
      driver.findElement(By.id("Email")).sendKeys(s.getCell(0,1).getContents());
      driver.findElement(By.id("Passwd")).sendKeys(s.getCell(1,0).getContents());
      Thread.sleep(5000);
      driver.findElement(By.cssSelector("input#signIn")).click();
      Thread.sleep(3000);
      }
  @BeforeTest
  public void beforeTest() {
      System.setProperty("webdriver.chrome.driver","\\E:\\lib\\chromedriver.exe");
      driver=new ChromeDriver();
      driver.get("https://accounts.google.com/ServiceLogin?service=mail");
  }

另外，您在点击登录按钮时会注意到，您正在寻找与TEXT "input.signin"的链接我认为您的意图是CSS选择器input类signin，但该元素也不存在。
