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);

    }
