org.openqa.selenium.NoSuchElementException

Question

我試圖導入登錄憑證，如：username和password使用XSL表，使用下面的代碼，但我得到了NoSuchElementException異常運行時，

我的XSL表如下：

 
    username | password

現在用：

• 日食
• webdriver.iostrea米
• 硒工具

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() { 
    } 
} 

的例外是：

問題出在哪裏？

Answer 1

如果您聽到這個問題，因爲當你get("http://gmail.com/") ID用（"f_id"和"f_pwd"不存在。

如果你的目的是要登錄，那麼你或許應該更具體與您的網址，你應該使用下面的代碼：

@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"); 
    } 

此外，你點擊登錄按鈕時要注意，你正在尋找與文本"input.signin"一個鏈接，我認爲你的意思做的，是一個CSS選擇器input帶班的signin但這ele也不存在。
