以博客园登录、退出为例：

下面是LoginPage的源码：

public class LoginPage {
      private WebDriver driver;     @FindBy(how = How.ID, id = "input1")     private WebElement userName;     @FindBy(how = How.ID, id = "input2")     private WebElement passWord;     @FindBy(how = How.ID, id = "signin")     private WebElement loginButton;     public  LoginPage(WebDriver driver)     {
          this.driver = driver; PageFactory.initElements(driver,this);       PageFactory.initElements一般放在自己的构造函数中，这样别的类调用的时候能保证每次都调用成功。     }     public void login(String username, String password)     {
          userName.clear();         passWord.clear();         userName.sendKeys(username);         passWord.sendKeys(password);         loginButton.click();         driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);     } } 下面是Mainpage的代码：

public class MainPage {
      private WebDriver driver;     @FindBy(how = How.LINK_TEXT, linkText = "登录")     WebElement loginLink;     @FindBy(how = How.LINK_TEXT, linkText = "退出")     WebElement logoutLink;     public MainPage(WebDriver driver)     {
          this.driver = driver; PageFactory.initElements(driver,this);      }     public void openMainPage(String url)     {
          driver.get(url);         //loginLink = driver.findElement(By.linkText("登录"));         //logoutLink = driver.findElement(By.linkText("退出"));     }     public void login(String userName, String passWord)     {
          loginLink.click();         WebDriverWait wait = new WebDriverWait(driver,300);         wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("input1")));         LoginPage loginPage = new LoginPage(driver);         loginPage.login(userName,passWord);     }     public void logout()     {
          logoutLink.click();         LogoutPage logoutPage = new LogoutPage(driver);         logoutPage.logout();     } }

下面是测试用的TestPage的代码：

public class TestPage {
      WebDriver driver;     @BeforeTest     public void setUp()     {
          ChromeOptions options = new ChromeOptions();         options.addArguments("--start-maximized", "allow-running-insecure-content", "--test-type");         options.addArguments("--user-data-dir="+System.getenv("USERPROFILE")+"/AppData/Local/Google/Chrome/User Data/Default");         System.setProperty("webdriver.chrome.driver", "C:\\Selenium\\chromedriver.exe"); //先设置这个         driver = new ChromeDriver(options);//再选择浏览器     }     @Test     public void testMainPage() throws Exception     {
          //MainPage mainPage = PageFactory.initElements(driver,MainPage.class);   MainPage mainPage =new MainPage(driver);    有些人把PageFactory放在这里调用，其实是不合理的，这样容易漏掉LoginPage里的PageFactory         mainPage.openMainPage("http://www.cnblogs.com");         mainPage.login("WebdriverTest","Password123!");         mainPage.logout();     } }
