我正在尝试为https://www.booking.com/编写测试，只是为了我自己的经验。因此，我遇到了一个问题：尝试更改表单中的客人数量时，我不断收到 NoSuchElementException。

Message: OpenQA.Selenium.NoSuchElementException : no such element: Unable to locate element: 
{"method":"xpath","selector":"//*[@id="xp__guests__inputs - container"]/div/div/div[2]/div/div[2]/button[2]"}
  (Session info: chrome=79.0.3945.88)

我已经尝试过关于 SOF 的任何建议：

driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(120);

和new WebDriverWait(driver, TimeSpan.FromSeconds(200)).Until(condition: ExpectedConditions.ElementIsVisible(By.XPath("//*[@id=\"xp__guests__inputs - container\"]/div/div/div[1]/div/div[2]/button[2]")));

并尝试使用 XPath Axes 访问我需要的元素

所有这些策略似乎都不适合我。

我的代码：

using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
using System;

namespace Tests
{
    public class Tests
    {
        IWebDriver driver;

        [SetUp]
        public void StartBrowser()
        {
            driver = new ChromeDriver("D:\\Development\\chromedriver_win32");
            //driver.Url = "https://www.booking.com/";
        }
        [Test]
        public void TestAccomodation()
        {
            driver.Url = "https://www.booking.com/";
            IWebElement cityTextbox = driver.FindElement(By.XPath("//*[@id=\"ss\"]"));
            cityTextbox.SendKeys("Осака");
            IWebElement accomodationDate = driver.FindElement(By.XPath("//*[@id=\"frm\"]/div[1]/div[2]/div[1]/div[2]/div/div/div/div"));
            accomodationDate.Click();

            driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);
            IWebElement accArival = driver.FindElement(By.XPath("//*[@id=\"frm\"]/div[1]/div[2]/div[2]/div/div/div[3]/div[2]/table/tbody/tr[2]/td[2]"));
            accArival.Click();

            driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);
            IWebElement accDeparture = driver.FindElement(By.XPath("//*[@id=\"frm\"]/div[1]/div[2]/div[2]/div/div/div[3]/div[2]/table/tbody/tr[3]/td[2]"));
            accDeparture.Click();


            IWebElement partyMembers = driver.FindElement(By.XPath("//*[@id=\"frm\"]/div[1]/div[3]"));
            partyMembers.Click();


            //IWebElement container = driver.FindElement(By.XPath("//**[@id=\"frm\"]/div[1]/div[3]/div")); //ERROR!

            IWebElement partyChildren = driver.FindElement(By.XPath("//*[@id=\"xp__guests__inputs - container\"]/div/div/div[2]/div/div[2]/button[2]")); //ERROR!
            partyChildren.Click();
        }

        [TearDown]
        public void CloseBrowser()
        {
            System.Threading.Thread.Sleep(5000);
            driver.Close();
        }

    }
}

To set number of guests in the form of https://www.booking.com/ as Adults as 3, Children as 2 and Rooms as 2 you have to induce WebDriverWait for the ElementToBeClickable() and you can use the following Locator Strategies:

  • Code Block:

    driver.Url = "https://www.booking.com/";
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("label.xp__input#xp__guests__toggle"))).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("button[aria-label='Increase number of Adults']"))).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("button[aria-label='Increase number of Children']"))).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("button[aria-label='Increase number of Children']"))).Click();
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("button[aria-label='Increase number of Rooms']"))).Click();
