Java和Selenium顯示Google搜索結果的最佳方式

Question

我對Selenium和Java非常陌生，但我試圖製作一個簡單的程序，它可以加載谷歌，執行搜索，然後顯示多少結果以及加載需要多長時間谷歌搜索。我正在與結果的問題，並獲得該顯示

import org.openqa.selenium.firefox.FirefoxDriver; 
import org.openqa.selenium.support.ui.ExpectedConditions; 
import org.openqa.selenium.support.ui.WebDriverWait; 
import org.openqa.selenium.By; 
import org.openqa.selenium.WebElement; 

public class GoogleSearch { 

public static void main(String[] args) { 

    FirefoxDriver driver = new FirefoxDriver(); 
    driver.get("http://google.com"); 


    WebElement searchTextBox = driver.findElement(By.id("lst-ib")); 
    searchTextBox.sendKeys("Colin"); 

    String pageUrl = driver.getCurrentUrl(); 
    System.out.println(pageUrl); 

    WebElement searchButton = driver.findElement(By.className("lsb")); 
    searchButton.click(); 

    String pageTitle = driver.getTitle(); 
    System.out.println("Page title is:" + pageTitle); 


    WebDriverWait wait = new WebDriverWait(driver, 5);// 5 seconds 
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("resultsStats"))); 
    driver.findElement(By.id("resultsStats")); 

    WebElement results = driver.findElement(By.id("resultsStats")); //displays # of results from search 
     System.out.println(results); 

    //driver.quit(); 


} 
} 

下面是我得到的結果：

https://www.google.com/?gws_rd=ssl 
Page title is:Google 
Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"id","selector":"resultsStats"} 
Command duration or timeout: 13 milliseconds

Answer 1

這不是resultsStats，它是resultStats。改變一樣，你很好走！

wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("resultStats"))); 
driver.findElement(By.id("resultStats")); 

WebElement results = driver.findElement(By.id("resultStats")); //displays # of results from search
