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 DriverALL org.openqa.selenium.firefox.FirefoxDriver
Chrome DriverALLorg.openqa.selenium.chrome.ChromeDriver
InternetExplorer DriverWindowsorg.openqa.selenium.ie.InternetExplorerDriver
HtmlUnit DriverALLorg.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
http://pic002.cnblogs.com/images/2012/311516/2012021013074646.jpg 下面代码是我录制的一个google搜索“selenium”关键安的操作：
http://common.cnblogs.com/images/copycode.gif
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？
