java - 如何自动化 Google 主页自动建议？

Question

这是我的测试类，包含所有代码行。我认为问题出在 xpath 中，因为它无法找到元素。

package practice;

import java.util.List;

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class selPractice {

public static void main(String[] args) throws InterruptedException
{
    String key="webdriver.chrome.driver";
    String value="./software/chromedriver.exe";
    System.setProperty(key, value);
    WebDriver driver=new ChromeDriver();
    driver.get("https://www.google.com");
    //to automate auto suggestion 

driver.findElement(By.xpath("//input[@title='Search']")).sendKeys("motogp");
List<WebElement>motolist=driver.findElements(By.xpath("//ul[@role='listbox]
//li/descendant::div[@class='sbl1']"));
    Thread.sleep(2000);

    int count=motolist.size();
    System.out.println(count);
    for(WebElement list:motolist)
    {
        String text=list.getText();
        System.out.println(text);
    }
}
}

从 Google Home Page 上的搜索框提取自动建议您必须为 visibilityOfAllElements 引入 WebDriverWait，并且可以使用以下解决方案:

• 代码块:

  import java.util.List;
  
  import org.openqa.selenium.By;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.WebElement;
  import org.openqa.selenium.chrome.ChromeDriver;
  import org.openqa.selenium.chrome.ChromeOptions;
  import org.openqa.selenium.support.ui.ExpectedConditions;
  import org.openqa.selenium.support.ui.WebDriverWait;
  
  public class Google_Auto_Suggestions {
  
      public static void main(String[] args) {
  
          System.setProperty("webdriver.chrome.driver", "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("http://www.google.com");
          new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.name("q"))).sendKeys("motogp");
          List<WebElement> motolist = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.xpath("//form[@action='/search' and @role='search']//ul[@role='listbox']//li//span")));
          for(WebElement list:motolist)
          {
              String text=list.getText();
              System.out.println(text);
          }
      }
  }
