selenium2.0处理muti-Windows 、 Frames 、Popup Dialogs

selenium2.0处理多窗口，弹窗等，只需要调用WebDriver 嵌套类：TargetLocator(driver.switchTo.……)，如下：

driver.switchTo().window("windowName");//target="windowName" ，或者 直接都是使用获取当前窗口句柄来定位

driver.switchTo().frame("frameName");

Alert alert = driver.switchTo().alert();

注：当 driver.switchTo().alert()得到alert后，就可以对alert做accept,dismiss,读alert内容，或者填写prompt，适合于alert/confirm/prompts

下面是具体实例操作代码：

package mavenSelenium;

import java.util.Set;

import org.openqa.selenium.By;
import org.junit.*;
import org.openqa.selenium.Alert;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class VariableWindows extends Assert {

    protected WebDriver driver;
    @Before
    public void setUp(){
        driver=new FirefoxDriver();
    }
    
    @Test
    public void test()  throws Exception{
        driver.get("file:///C:/Users/jennifer.huang/Desktop/AlertConfirmPromptPage.html");
        //1、操作confirm弹出框
        WebElement e1=driver.findElement(By.id("btnConfirm"));
        e1.click();
        Alert alert11=driver.switchTo().alert();
        if(!alert11.getText().contains("Choose an option.")){
            fail("The confirm should contains [Choose an option.]");
        }
        alert11.accept();
        String expectString="Confirmed";
        verifyResult(expectString);//验证结果Assert.fail
        
        e1.click();
        Alert alert12=driver.switchTo().alert();
        alert12.dismiss();
        expectString="Rejected!";
        verifyResult(expectString); 
        
        //2、操作Alert
        WebElement e2=driver.findElement(By.id("btnAlert"));
        e2.click();
        Alert alert21=driver.switchTo().alert();
        if(!alert21.getText().contains("I'm blocking")){
            fail("Alert should conatins [I'm blocking]");
        }
        alert21.accept();
        expectString="Alert is gone";
        verifyResult(expectString);
        
        //3、操作prompt
        WebElement e3=driver.findElement(By.id("btnPrompt"));
        e3.click();
        Alert alert31=driver.switchTo().alert();
        expectString="selenium2.0";
        alert31.sendKeys(expectString);
        alert31.accept();
        verifyResult(expectString);
        
        //4、操作新Tab
        //4.1 打开新tab  target="_blank"
        WebElement e4=driver.findElement(By.id("linkNewWindow"));
        e4.click();
        changeFocus("百度一下，你就知道");
        System.out.println("当前窗口title："+driver.getTitle());
        //4.2按钮打开新窗口
        changeFocus("主窗口");
        System.out.println("当前窗口title："+driver.getTitle());
        WebElement e5=driver.findElement(By.id("btnNewNamelessWindow"));
        e5.click();
        changeFocus("博客园 - 程序员的网上家园");
        System.out.println("当前窗口title："+driver.getTitle());
        //4.3按钮打开新窗口
        Thread.sleep(5000);
        changeFocus("主窗口");
        WebElement e6=driver.findElement(By.id("btnNewNamedWindow"));
        e6.click();
        changeFocus("博客园 - 程序员的网上家园");
        
        //另外selenium2.0其他操作窗口语句有：
        driver.get("http://www.google.com");//Load a new web page in the current browser window
        driver.navigate().to("http://www.cnblogs.com/jenniferhuang/"); //和driver.get(“url”)，都是新载一个页面
        Thread.sleep(2000);
        driver.navigate().back();  //move backwards in  browser’s history:
        Thread.sleep(2000);
        driver.navigate().forward();  //move forwards in  browser’s history:

    }
    @After
    public void tearDoown(){
        driver.quit();
    }
    
    /**
     * 验证结果
     * @param expectString
     */
    public void verifyResult(String expectString){
        String resultString=driver.findElement(By.id("output")).getText();
        if(!resultString.contains(expectString)){
            fail("Element [" + By.id("output") + "] should contains [" + expectString + "] ; but now it contains: " + resultString);
        }
    }
    /**
     * 窗口跳转， 通过title来确定要跳到哪个窗口
     * @param windowTitle
     */
    public void changeFocus(String windowTitle){
        for(String handle:driver.getWindowHandles()){
            if(driver.switchTo().window(handle).getTitle().equals(windowTitle)){
                driver.switchTo().window(handle);
                break;
            }
        }
    }
