Woot web sites have one item for sale every 24 hours.* author Tony*/public interface Woot {/*** Defines the interface of the method we use to get the price* of the item for sale on a Woot website* param selenium the selenium object we pass in which is used to interact* with the browser/web page* return String representation of the price of the item for sale*/public String getPrice(Selenium selenium);/*** Defines the interface of the method we use to get the product name* of the item for sale on a Woot website* param selenium the selenium object we pass in which is used to interact* with the browser/web page* return String representation of the product name of the item for sale*/public String getProductName(Selenium selenium);} 然后我多次实现了此接口以表示各种woot页面的实际行为–例如如果是winewoot页面 public class WineWoot extends BaseWoot {/*** Constructor* param url pass in the url of the web site*/public WineWoot(String url) {super(url);}/*** Implementation of the method to get the price of the object for sale on* the Woot web site.*/public String getPrice(Selenium selenium) {//if you need to update the xpath to the piece of text of interest - use xpather firefox pluginString xPath //html/body/header/nav/ul/li[8]/section/div/a/div[3]/span;selenium.waitForCondition(selenium.isElementPresent(\xpath xPath \);, 12000);return selenium.getText(xPath) ;}/*** Implementation of the method to get the product name of the item for sale* on the Woot web site**/public String getProductName(Selenium selenium) {//if you need to update the xpath to the piece of text of interest - use xpather firefox pluginString xPath //html/body/header/nav/ul/li[8]/section/div/a/div[2];selenium.waitForCondition(selenium.isElementPresent(\xpath xPath \);, 12000);return selenium.getText(xPath) ;}} 注意–当时我使用了xPather插件–对于最新版本的firefox无效因此现在我使用firebug 。 然后我写了实际的“测试” package uk.co.doogle;import com.thoughtworks.selenium.*;import java.io.BufferedWriter;import java.io.FileWriter;import java.util.ArrayList;import java.util.List;/*** This class is where we define tests of the Woot web sites* author Tony**/public class TestWoots extends SeleneseTestCase {/*** Outputstream for our results file*/private BufferedWriter out;/*** Our list of Woot web sites we want to test*/private ListBaseWoot sites new ArrayListBaseWoot();/*** This is where we do any set up needed before our test(s) run.* Here we add the list of Woot web sites we want to test and we create an* output stream ready to write results to file*/public void setUp() throws Exception {sites.add(new BaseWoot(http://www.woot.com/));sites.add(new ShirtWoot(http://shirt.woot.com/));sites.add(new WineWoot(http://wine.woot.com/));try {//lets append to our file...FileWriter fstream new FileWriter(out.csv, true);out new BufferedWriter(fstream);out.write(Site, Product Name, Product Price);out.newLine();} catch (Exception e) {System.err.println(Error creating a file to write our results to: e.getMessage());}}/*** Tests getting the item name and price for the item for sale on each Woot web site we test.
