标题: 菜鸟学自动化测试（九）----WebDirver

关于什么是WebDirver，上一节做了简单的描述，环境也在上一章中搭建完成。

下面我们拷贝了官网提供的一个实例。让其在我们的eclipse中运行。

Selenium WebDirver 代码如下：

package MySel20Proj;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Selenium2Example  {
public static void main(String[] args) {
      // 用Firefox driver创建一个新的的实例
      //注意:其他的代码依赖于界面
      //不执行

      System.setProperty ( "webdriver.firefox.bin" , "E:/Program Files/Mozilla Firefox/firefox.exe" );
      WebDriver driver = new FirefoxDriver();// 这里我们可以使用firefox来运行测试用例
      //WebDriver driver = new ChromeDriver(); //这是chrome浏览器的驱动
      //WebDriver driver = new InternetExplorerDriver(); //这是IE浏览器的驱动
   // WebDriver driver = new HtmlUnitDriver(); //这是一个无界面测试模式，不用打开浏览器，通过后台输入来判断测试用例是否通过

      // 现在用这个来访问谷歌
      driver.get("http://www.google.com");
      // 也可以用下面的方式访问谷歌
      // driver.navigate().to("http://www.google.com");

      // 找到文本输入元件的名字
      WebElement element = driver.findElement(By.name("q"));

      // 在搜索框内输入“cheese!”
      element.sendKeys("Cheese!");

      // 现在递交表格. WebDriver会发现我们的形式元素
      element.submit();

      // 后台打印输出，检查网页的标题
      System.out.println("Page title is: " + driver.getTitle());

      // 谷歌的搜索是渲染过的动态JavaScript. 等待页面加载，暂停10秒
      (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
         public Boolean apply(WebDriver d) {
            return d.getTitle().toLowerCase().startsWith("cheese!");
         }
      });

      // Should see: "cheese! - Google Search"
      System.out.println("Page title is: " + driver.getTitle());

      //关闭浏览器
      driver.quit();
}
}

运行时报出了错误；

Exception in thread "main" org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: XP

Build info: version: '2.16.1', revision: '15405', time: '2012-01-05 12:30:12'

我们只要在WebDriver driver = new FirefoxDriver(); 前面指定我们浏览器的具体信息即可：

System.setProperty ( "webdriver.firefox.bin" , "E:/Program Files/Mozilla Firefox/firefox.exe" );

WebDriver driver = new FirefoxDriver();

WebDirver 的实现：

驱动名称	对操作系统的支持	调用的接口
FireFox Driver	ALL	org.openqa.selenium.firefox.FirefoxDriver
Chrome Driver	ALL	org.openqa.selenium.chrome.ChromeDriver
InternetExplorer Driver	Windows	org.openqa.selenium.ie.InternetExplorerDriver
HtmlUnit Driver	ALL	org.openqa.selenium.htmlunit.HtmlUnitDriver

什么情况下选用WebDirver ？

（1）Selenium-1.0不支持的浏览器功能。
（2）multiple frames, multiple browser windows, popups, and alerts.
（3）页面导航。
（4）下拉。
（5）基于AJAX的UI元素。

同样,我们的selenium IDE也支持WebDriver类型脚本的导出。

将我们录制好的脚本导出为junit(WebDriver) 类型

下面代码是我录制的一个google搜索“selenium”关键安的操作：

package com.test.hzh;

import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;

public class Test1 {
private WebDriver driver;
private String baseUrl;
private StringBuffer verificationErrors = new StringBuffer();
@Before
public void setUp() throws Exception {
      System.setProperty ( "webdriver.firefox.bin" , "E:/Program Files/Mozilla Firefox/firefox.exe" );
      driver = new FirefoxDriver();
      baseUrl = "http://www.google.com.hk/";
      driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}

@Test
public void test() throws Exception {
      driver.get(baseUrl + "/");
      driver.findElement(By.id("lst-ib")).clear();
      driver.findElement(By.id("lst-ib")).sendKeys("selenium");
      driver.findElement(By.name("btnK")).click();
}

@After
public void tearDown() throws Exception {
      driver.quit();
      String verificationErrorString = verificationErrors.toString();
      if (!"".equals(verificationErrorString)) {
         fail(verificationErrorString);
      }
}

private boolean isElementPresent(By by) {
      try {
         driver.findElement(by);
         return true;
      } catch (NoSuchElementException e) {
         return false;
      }
}
}

暂时看到有点吃力啊

呜呜，还行，希望可以一起交流一下

对于菜鸟的我来说果然吃力啊~~

打开浏览器，接下来就不动了。
这个是什么原因？
