selenium2.0处理case实例（二）

本文通过具体代码处理过程， 来展示selenium中一些比较不常用的类的用法

       1、javascriptExcutor，通过将driver强转成JavascriptExecutor类型， 调用executeScript()就可执行javascript;

       2、TakesScreenshot，自动化测试中，截图可以帮助我们直观的定位错误、记录测试步骤；webdriver的截图功能十分方便，只需要driver.get到当前要截图的页面， 再将driver强转成TakesScreenshot 类型，调用getScreenshotAs(getScreenshotAs)方法得到截图文件

       3、DragAndDrop，模拟拖放操作， 使用actions.dragAndDrop(source, target).perform();来完成。source是要拖拉操作的对象，比如一张图片等， target是要放置的位置

       4、Select类，下拉框类型的控件，可以通过Select select=new Select(driver.findElement(By.id("select1"))); 来得到Select对象， 就可以对选项进行操作，比如，提供了“清空选择项”，“通过text/index/value来选择选项”，“获得所有的选项”，“获得当前选择的选项”等方法，具体可参见api，用法可参见博客“selenium2.0处理case实例（一）”

下面代码按照顺序，列出上述类具体使用过程和场景：

package mavenSelenium;
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.interactions.Actions;
import com.google.common.io.Files;

public class TestBlog extends Assert {
    WebDriver driver;
    
    @Before
    public void init(){
        driver=new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    }
    
    @Test
    public void test()throws Exception{
        //1、driver  execute JavaScript
        driver.get("http://www.baidu.com");
        JavascriptExecutor js=(JavascriptExecutor)driver;
        String title=(String)js.executeScript("return document.title");
        System.out.println(title);
        
           //String script="function timeStamp(){ var d = new Date(); var m=d.getMonth()+1;var m=(m>9)?m:"0"+m; var dd=(d.getDate()>9)?d.getDate():"0"+d.getDate();var hh=(d.getHours()>9)?d.getHours():"0"+d.getHours();var mm=(d.getMinutes()>9)?d.getMinutes():"0"+d.getMinutes(); var ss=(d.getSeconds()>9)?d.getSeconds():"0"+d.getSeconds();var timeStamp=""+d.getFullYear()+m+dd+hh+mm+ss; return timeStamp; }var rs;rs=timeStamp();";
        String script="var d = new Date(); var m=d.getMonth()+1;var m=(m>9)?m:"0"+m; var dd=(d.getDate()>9)?d.getDate():"0"+d.getDate();     var hh=(d.getHours()>9)?d.getHours():"0"+d.getHours(); var mm=(d.getMinutes()>9)?d.getMinutes():"0"+d.getMinutes(); var ss=(d.getSeconds()>9)?d.getSeconds():"0"+d.getSeconds();var timeStamp=""+d.getFullYear()+m+dd+hh+mm+ss; return timeStamp;";
        System.out.println(script);
        String timestamps=(String)js.executeScript(script);
        System.out.println(timestamps);
        
        //2、TakesScreenshot
        File srcFile=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
        String descFilePath="d:\test2.jpeg";
        Files.copy(srcFile, new File(descFilePath));
        File descFile=new File(descFilePath);
        assertTrue(descFile.exists());
        
        //3、Drag And Drop
        driver.get("https://www.casa.com/login.qs?returnurl=/StyleBoard/Detail.qs?StyleBoardId=9468");
        driver.findElement(By.id("emailTextBox")).sendKeys("jennifer.huang@suryani.cn");
        driver.findElement(By.id("PwdTextBox_Security")).sendKeys("abc123");
        driver.findElement(By.id("SignInButton")).click();
        Thread.sleep(2000);
        WebElement source1=driver.findElement(By.xpath("//div[@id='SBProductBox1']/div/a/img"));
        WebElement target1=driver.findElement(By.xpath("//div[contains(@class,'SBDrag') and child::div[@id='SBProductBox2']]"));
        Actions actions=new Actions(driver);
        actions.dragAndDrop(source1, target1).perform();
        Thread.sleep(2000);
        WebElement source2=driver.findElement(By.xpath("//div[@id='SBProductBox2']/div/a/img"));
        WebElement target2=driver.findElement(By.xpath("//div[contains(@class,'SBDrag') and child::div[@id='SBProductBox1']]"));
        actions.dragAndDrop(source2, target2).perform();        
    }
    public void tearDown(){
        driver.quit();
    }

}

dragAndDropToObject(locatorOfObjectToBeDragged, locatorOfDragDestinationObject)

dragAndDrop(locator, movementsString)  //movementsString - offset in pixels from the current location to which the element should be moved, e.g., "+70,-300"

dragAndDrop(Point, Point) // Point point = driver.findElement(locator).getLocation();  get (x,y)
