WebDriver拾级而上·之十 封装与重用

WebDriver对页面的操作，需要找到一个WebElement，然后再对其进行操作，比较繁琐：

// Find the text inputelement by its name
WebElement element = driver.findElement(By.name("q"));
 // Enter something to search for
element.sendKeys("Cheese!");

我们可以考虑对这些基本的操作进行一个封装，简化操作。比如，封装代码：

protected void sendKeys(By by, String value){
   driver.findElement(by).sendKeys(value);
}

那么，在测试用例可以这样简化调用：

sendKeys(By.name("q"),"Cheese!");

看，这就简洁多了。

类似的封装还有：

package com.drutt.mm.end2end.actions;

import java.util.List;
import java.util.NoSuchElementException;
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.ui.WebDriverWait;

import com.drutt.mm.end2end.data.TestConstant;

public class WebDriverAction {

   //protected WebDriverdriver;
   protected RemoteWebDriverdriver;
   protected WebDriverWaitdriverWait;


    protected booleanisWebElementExist(By selector) { 
        try { 
            driver.findElement(selector);
            return true; 
        } catch(NoSuchElementException e) { 
            return false; 
        } 
    } 

    protected StringgetWebText(By by) { 
        try { 
        return driver.findElement(by).getText();
        } catch (NoSuchElementException e) { 
            return "Textnot existed!"; 
        } 
    } 

    protected voidclickElementContainingText(By by, String text){
        List<WebElement>elementList = driver.findElements(by);
        for(WebElement e:elementList){
            if(e.getText().contains(text)){
                e.click();
                break;
            }
        }     
    }

    protected StringgetLinkUrlContainingText(By by, String text){
        List<WebElement>subscribeButton = driver.findElements(by);
        String url = null;
        for(WebElement e:subscribeButton){
            if(e.getText().contains(text)){
                url =e.getAttribute("href");
                break;
            }
        }
        return url;
    }

    protected void click(Byby){
       driver.findElement(by).click();
       driver.manage().timeouts().implicitlyWait(TestConstant.WAIT_ELEMENT_TO_LOAD,TimeUnit.SECONDS); 
    }

    protected StringgetLinkUrl(By by){
        return driver.findElement(by).getAttribute("href");
    }

    protected void sendKeys(Byby, String value){
       driver.findElement(by).sendKeys(value);
    }
