NoSuchElementException:没有这样的元素:尝试通过 Selenium 单击 amazon.co.uk 上的下拉元素时无法定位元素

NoSuchElementException: no such element: Unable to locate element while trying to click dropdown element on amazon.co.uk through Selenium

我是 运行 selenium/intelliJ/Java 的自动化测试。网络驱动程序应该单击亚马逊导航栏上的下拉菜单,然后单击下拉菜单中的 link 之一。它正确地完成了这两件事,下拉选项导致它的 link,但是 selenium 测试本身失败了,这里是错误:

org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"link text","selector":"Full Shop Directory"}

这是我的代码:

package com.testing.webdriver;

import io.github.bonigarcia.wdm.WebDriverManager;
import org.junit.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.WebElement;


import java.util.Random;
import java.util.concurrent.TimeUnit;

public class MyFirstTest {
    WebDriver driver = new ChromeDriver();

    @BeforeClass
    public static void setupWebdriver() {
        WebDriverManager.chromedriver().setup();
    }


    private static final By SHOP_BY_DEPARTMENT = By.cssSelector("#nav-link-shopall");
    private static final By SHOP_ALL = By.cssSelector("#nav-flyout-shopAll > div.nav-template.nav-flyout-content.nav-tpl-itemList > a");



    @Test
    public void startWebdriver() {

        driver.navigate().to("https://www.amazon.co.uk/");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.manage().window().maximize();
        WebElement shopByDepartment = driver.findElement(SHOP_BY_DEPARTMENT);
        shopByDepartment.click();

        WebElement ShopAllNav = driver.findElement(By.linkText("Full Shop Directory"));
        ShopAllNav.click();

        Assert.assertTrue("matches current url",
                driver.getCurrentUrl().matches("https://www.amazon.co.uk/gp/site-directory/ref=nav_shopall_fullstore"));

    }

    @After
    public void breakdown() throws InterruptedException {
        Thread.sleep(20000);
        driver.close();
    }

测试应该按照我所说的那样通过。正如错误所说,我认为这与下拉菜单中的 link 有关,但我仍然不知道如何纠正这个问题。如有任何帮助,我们将不胜感激。

我在亚马逊看到的:

'full shop directory' 不是(真正的 link 文本)。 如果元素是 <a>this is a text</a> 那么我认为它是 link 文本。

在您的情况下,文本由大量空格组成 **********完整商店目录************ 并且这种不稳定可能会导致问题(在你的情况下可能)。

将您的定位器更正为结构安全的,然后重试。

示例: xpath: //a/span[@class='nav-text' and text()='Full Shop Directory']

更新: 你的测试写错了或者不知道你的实际目标是什么。

你的工作:

  1. 单击导航菜单和 'full shop directory' 相同的视图页面是 越来越开放。 link不同。
  2. 单击 'shop by department' 中的按钮(隐藏)
  3. 断言 urls...

建议的步骤:

  1. 移动到 'shop by department' 并触发下拉菜单。

  2. 单击下拉菜单中的 'full shop directory' 按钮。

  3. 等待页面加载

  4. 声明页面 url.

代码:

driver.navigate().to("https://www.amazon.co.uk/");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.manage().window().maximize();
WebElement shopByDepartment = driver.findElement(SHOP_BY_DEPARTMENT);

Actions ac = new Actions(driver);
ac.moveToElement(shopByDepartment).perform();

WebElement ShopAllNav = driver.findElement(By.linkText("Full Shop Directory"));
ShopAllNav.click();

Assert.assertTrue(driver.getCurrentUrl().matches("https://www.amazon.co.uk/gp/site-directory/ref=nav_shopall_fullstore"), "matches current url");

代码已经过测试并确认可以正常工作。

您需要等待特定组件可见。在其可见性之后,您可以对其应用操作。

您可以试试下面的代码。

WebElement ShopAllNav = driver.findElement(By.linkText("Full Shop Directory"));
WebDriverWait wait = new WebDriverWait(driver,200);
wait.until(ExpectedConditions.visibilityOf(ShopAllNav));
ShopAllNav.click();

要展开 Amazon 导航栏上的 下拉菜单 ,您不需要 click()而是 Mouse Hover 导致 WebDriverWait,您可以使用以下解决方案:

  • 代码块:

    System.setProperty("god.bless.you", "C:\Utility\BrowserDrivers\chromedriver.exe");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("start-maximized");
    options.addArguments("disable-infobars");
    options.addArguments("--disable-extensions"); 
    WebDriver driver =  new ChromeDriver(options);
    driver.get("https://www.amazon.co.uk/");
    new Actions(driver).moveToElement(new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div#nav-shop>a#nav-link-shopall")))).perform();
    new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("div.nav-catFlyout.nav-flyout div.nav-template.nav-flyout-content.nav-tpl-itemList a"))).click();
    Assert.assertTrue(driver.getCurrentUrl().matches("https://www.amazon.co.uk/gp/site-directory/ref=nav_shopall_fullstore"));
    driver.quit();
