的webdriver：无法点击“单选按钮”

Question

我已经创建了包含在两个单独的类

两套代码任务所需：需要点击PH支付页面上的“现金”按钮。

1. 第一类=简单的类，简单的代码=代码的作品，可以点击现金选项。
   

2. 二类=设置包含页面对象，框架使用不同的结构=代码无法到达付款页面时，在现金选择权点击=“org.openqa.selenium.StaleElementReferenceException：元素不在缓存中找到”
   
   

3. 我已经在两个类中使用了相同的定位器，但是当在'2'中使用正确的定位器时，它无法点击'收音机'按钮;如上所列，我得到列出的错误;我试图创建定制方法;使用循环等和不同的定位器，但没有任何工作。
   

工作代码和类：

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.firefox.FirefoxDriver; 
import org.testng.annotations.BeforeClass; 
import org.testng.annotations.BeforeSuite; 
import org.testng.annotations.Test; 

public class TestClass { 

    @Test 
    public void test() throws InterruptedException { 
     //System.setProperty("webdriver.chrome.driver", "C:\\Users\\GBruno\\Desktop\\masteringSelenium\\Framework\\src\\test\\resources\\chromedriver.exe"); 
     // WebDriver driver = new ChromeDriver(); 
     WebDriver driver = new FirefoxDriver(); 

     driver.get("http://www.pizzahut.co.uk"); 
     driver.manage().window().maximize(); 

     //click pizza button 
     driver.findElement(By.cssSelector("div[id='page'] [href='/menu/pizza']")).click(); 

     //select any pizza to start order 
     driver.findElement(By.cssSelector("div[class='col-xxs-8 col-xs-6 col-sm-8 col-md-7 col-lg-6'] *> button")).click(); 

     //enter postcode and find hut 
     Thread.sleep(2000); 
     driver.findElement(By.cssSelector("#ajax-postcode-txt")).sendKeys("TS1 4AG"); 
     driver.findElement(By.cssSelector(" #get-store-btn")).click(); 


     //click start order button 
     Thread.sleep(3000); 
     driver.findElement(By.xpath(".//*[@id='store-collection-section']/div[2]/div[4]/div[4]/div/a")).click(); 

     //add pizza 
     Thread.sleep(5000); 
     driver.findElement(By.xpath(".//*[@id='pizza-product-list']/div/div[1]/div/div[2]/div[2]/div[3]/div/form/button")).click(); 

     //click mini basket 
     driver.findElement(By.xpath("html/body/nav/div/div/div[3]/div/div[1]/div[2]/span[3]")).click(); 

     Thread.sleep(2000); 
     //click checkout 
     driver.findElement(By.xpath(".//*[@id='divBasket']/div[1]/div/div[2]/div[2]/a")).click(); 

     Thread.sleep(2000); 
     //checkout guest & enter details 
     driver.findElement(By.xpath(".//*[@id='frmCheckout']/div[2]/div/div[1]/a")).click(); 
     driver.findElement(By.xpath(".//*[@id='ddlTitleSelectBoxIt']")).click(); 
     driver.findElement(By.linkText("Mr")).click(); 
     driver.findElement(By.xpath(".//*[@id='FirstName']")).sendKeys("Tom"); 
     driver.findElement(By.xpath(".//*[@id='LastName']")).sendKeys("Hanks"); 
     driver.findElement(By.xpath(".//*[@id='EmailAddress']")).sendKeys("tom_hanks12344566@mail.com"); 
     driver.findElement(By.xpath(".//*[@id='ConfirmEmailAddress']")).sendKeys("tom_hanks12344566@mail.com"); 
     driver.findElement(By.xpath(".//*[@id='PhoneNumber']")).sendKeys(""); 

     driver.findElement(By.xpath(".//*[@id='btnFindAddress']")).click(); 

     Thread.sleep(3000); 
     driver.findElement(By.xpath(".//*[@id='ddlAddressesToChooseSelectBoxItArrowContainer']")).click(); 
     driver.findElement(By.linkText("K F C 189-191 Linthorpe Road Middlesbrough TS14AG")).click(); 
     driver.findElement(By.xpath(".//*[@id='btnContinue']")).click(); 

     driver.findElement(By.xpath(".//*[@id='payment-methods']/div[1]/div/label/input")).click(); 

    } 
} 

代码dosnt工作：

public void selectPaymentTypeAndPayForOrder() throws Exception { 
    Thread.sleep(3000); 
    driver.findElement(By.xpath(".//*[@id='payment-methods']/div[1]/div/label/input")).click(); 

    driver.findElement(By.cssSelector(" form[id='CheckoutForm'] input[data-paymentname='Cash']")).click(); 

Answer 1

的弗洛翼码解决了这个问题：

List<WebElement> iframes = driver.findElements(By.tagName("iframe")); 
if(iframes.size() == 0) { 
    Assert.fail();  
} else { 
    // Frames present  
    Assert.assertTrue(true); 
}
