Page-Object思想

为什么要使用page-object
集中管理元素对象
集中管理一个page内的公共方法
后期维护方便

集中管理元素对象
实现方法：

调用方法：
WebElement element = driver.findElement(Test7.input);

Page类的实现
目的：

有了page类后，在具体的脚本中，要用到哪个page，就new这个page的对象，然后调用里面的公共方法即可
实现方法：

Page类的实现
说明：
Page类是一个基础类，其它的Page类都要继承该类，比如：



在具体的脚本中的使用方法：

具体代码如下：

Page.java具体代码：

 package com.selenium.utils;

 import org.openqa.selenium.By;
 import org.openqa.selenium.WebDriver;
 import org.openqa.selenium.WebElement;
 import org.openqa.selenium.support.ui.ExpectedCondition;
 import org.openqa.selenium.support.ui.WebDriverWait;

 public class Page {
     protected WebDriver driver;

     public Page(WebDriver driver) {
         this.driver = driver;
     }

     private boolean waitForToDisplayed(final By key) {
         boolean waitDisplayed = new WebDriverWait(driver, 10)
                 .until(new ExpectedCondition<Boolean>() {
                     public Boolean apply(WebDriver d) {
                         return d.findElement(key).isDisplayed();
                     }
                 });
         return waitDisplayed;
     }

     protected WebElement getElement(WebDriver driver, By key) {
         WebElement element = null;
         if (this.waitForToDisplayed(key)) {
             element = driver.findElement(key);
         }
         return element;
     }

 }

DemoPage.java:

package com.selenium.utils;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;

public class DemoPage extends Page {

    public static By input = By.id("user");
    public static By link = By.xpath("//div[id='link']/a");
    public static By select = By.cssSelector("select[name='select']");
    public static By radio = By.name("identity");
    public static By check = By.xpath("//div[@id='checkbox']/input");
    public static By button = By.className("button");
    public static By alert = By.className("alert");
    public static By action = By.className("over");
    public static By upload = By.id("load");
    public static String iframe = "aa";
    public static By multiWin = By.className("open");
    public static By wait = By.className("wait");

    public DemoPage(WebDriver driver) {
        super(driver);
        // TODO Auto-generated constructor stub
    }

    public void input(WebDriver Driver, String message) {
        WebElement element = this.getElement(Driver, input);
        element.sendKeys(message);
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    public void input_clear(WebDriver Driver) {
        WebElement element = this.getElement(Driver, input);
        element.clear();
    }
}

IframePage.java:

package com.selenium.utils;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;

public class IframePage extends Page {

	public static By input = By.id("user");
	public static By link = By.xpath("//div[id='link']/a");
	public static By select = By.cssSelector("select[name='select']");
	public static By radio = By.name("identity");
	public static By check = By.xpath("//div[@id='checkbox']/input");
	public static By button = By.className("button");
	public static By alert = By.className("alert");
	public static By action = By.className("over");
	public static By upload = By.id("load");
	public static By iframe = By.xpath("//iframe[@name='aa']");
	public static By multiWin = By.className("open");
	public static By wait = By.className("wait");

	public IframePage(WebDriver driver) {
		super(driver);
		// TODO Auto-generated constructor stub
	}

	public void input(WebDriver Driver, String message) {
		WebElement element = this.getElement(Driver, input);
		element.sendKeys(message);
		try {
			Thread.sleep(5000);
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	public void input_clear(WebDriver Driver) {
		WebElement element = this.getElement(Driver, input);
		element.clear();
	}

	public void switchToIframe(WebDriver Driver) {
		WebElement element = this.getElement(Driver, iframe);
		Driver.switchTo().frame(element);
		try {
			Thread.sleep(5000);
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	public void swipeOutFromIframe(WebDriver Driver) {
		Driver.switchTo().defaultContent();
	}
}

具体用起来是这样的：

TestPageObject.java

package com.selenium.test;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import com.selenium.utils.DemoPage;
import com.selenium.utils.IframePage;

public class TestPageObject {
    private WebDriver driver;

    @BeforeClass
    public void setUp() {
        driver = new FirefoxDriver();
        driver.manage().window().maximize();
        driver.navigate().to("file:///D:/BaiduYunDownload/selenium2/demo.html");
    }

    @AfterClass
    public void tearDown() {
        driver.close();
        // driver.quit();
    }

    @Test
    public void testInput() {
        DemoPage dp = new DemoPage(driver);
        dp.input(driver, "i love you");
        dp.input_clear(driver);

        IframePage ifp = new IframePage(driver);
        ifp.switchToIframe(driver);
        ifp.input(driver, "iframe");
        ifp.input_clear(driver);
        ifp.swipeOutFromIframe(driver);

        dp.input(driver, "i love you again");
        dp.input_clear(driver);
    }

}
