Selenium Web驱动程序：findElement（By.name…和无头浏览器

Question

我正在尝试遵循Selenium Webdrive教程

http://www.toolsqa.com/selenium-webdriver/headless-browser-testing-selenium-
webdriver/

有一个简单的测试，这里是步骤：

1. 开启网页http://google.com

2. 获取页面标题。

3. 搜索“ Selenium”

4. 再次检查页面标题。

从类代码示例开始，这是我的代码

package headlessBrowser;

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class TestOne {

public static void main(String[] args) {

    // Declaring and initialising the HtmlUnitWebDriver
    HtmlUnitDriver unitDriver = new HtmlUnitDriver();

    // open google.com webpage
    unitDriver.get("http://google.com");

    System.out.println("Title of the page is -> " + unitDriver.getTitle());

    // find the search edit box on the google page
    WebElement searchBox = unitDriver.findElement(By.name("q"));

    // type in Selenium
    searchBox.sendKeys("Selenium");

    // find the search button
    WebElement button = unitDriver.findElement(By.name("gbqfba"));

    // Click the button
    button.click();

    System.out.println("Title of the page is -> " + unitDriver.getTitle());

   }
}

尝试执行它，我遇到以下错误

Title of the page is -> 
Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element with name: q

没有打印页面名称：????? 似乎在页面中找不到“ q”元素。????

我检查了Firebug，似乎代码中存在“ q”元素（在下面的代码片段中查找name =“ q” …）

<input spellcheck="false" dir="ltr" style="border: medium none; padding: 0px; margin: 0px; height: auto; width: 100%; background: transparent url(&quot;data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw%3D%3D&quot;) repeat scroll 0% 0%; position: absolute; z-index: 6; left: 0px; outline: medium none;" aria-autocomplete="both" role="combobox" aria-haspopup="false" class="gsfi" id="lst-ib" maxlength="2048" name="q" autocomplete="off" title="Cerca" value="" aria-label="Cerca" type="text">

我在Windows 7上使用Eclipse Luna

有什么建议？先感谢您 …

我已经解决了....我在组织中的代理后面，所以我必须设置代理。

我发现了这一点：HtmlUnitDriver似乎没有正在加载page。

寻找FunThomas424242评论，并观看此链接https://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/htmlunit/HtmlUnitDriver.html

因此，正确的代码如下：

package headlessBrowser;

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class TestOne {

public static void main(String[] args) {

    // Declaring and initialising the HtmlUnitWebDriver
    HtmlUnitDriver unitDriver = new HtmlUnitDriver();

    // Necessary set Proxy if you're behind it !!!! 
    unitDriver.setProxy("proxy.YOUR-ORGANIZATION.COM", XXXX);

    // open google.com webpage
    unitDriver.get("http://www.google.com");

    System.out.println("Title of the page is -> " + unitDriver.getTitle());

    // find the search edit box on the google page
    WebElement searchBox = unitDriver.findElement(By.name("q"));

    // type in Selenium
    searchBox.sendKeys("Selenium");

    // find the search button
    WebElement button = unitDriver.findElement(By.name("btnG"));

    // Click the button
    button.click();

    System.out.println("Title of the page is -> " + unitDriver.getTitle());

   }
}

“核心”行如下

    // Necessary set Proxy if you're behind it !!!! 
    unitDriver.setProxy("proxy.YOUR-ORGANIZATION.COM", XXXX);

您必须在其中更新代理配置的位置。
