Question

我得到了代码如何在selenium中以正常方式使用WebDriverEventListener。但是不知道如何将它用于PageFactory模式。

代码如下，首先需要实现WebDriverEventListner接口

public class EventHandler implements WebDriverEventListener{

    private Log log = LogFactory.getLog(this.getClass());

    public void afterChangeValueOf(WebElement arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("inside method afterChangeValueOf on " + arg0.toString());
        log.info("inside method afterChangeValueOf on " + arg0.toString());
    }

    public void afterClickOn(WebElement arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("inside method afterClickOn on " + arg0.toString());
    }

    public void afterFindBy(By arg0, WebElement arg1, WebDriver arg2) {
        // TODO Auto-generated method stub
        log.info("Find happened on " + arg1.toString() 
                + " Using method " + arg0.toString());
    }

    public void afterNavigateBack(WebDriver arg0) {
        // TODO Auto-generated method stub

        log.info("Inside the after navigateback to " + arg0.getCurrentUrl());
    }

    public void afterNavigateForward(WebDriver arg0) {
        // TODO Auto-generated method stub
        log.info("Inside the afterNavigateForward to " + arg0.getCurrentUrl());
    }

    public void afterNavigateTo(String arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("Inside the afterNavigateTo to " + arg0);
    }

    public void afterScript(String arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("Inside the afterScript to, Script is " + arg0);
    }

    public void beforeChangeValueOf(WebElement arg0, WebDriver arg1) {
        // TODO Auto-generated method stub

        log.info("Inside the beforeChangeValueOf method");
    }

    public void beforeClickOn(WebElement arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("About to click on the " + arg0.toString());

    }

    public void beforeFindBy(By arg0, WebElement arg1, WebDriver arg2) {
        // TODO Auto-generated method stub
        log.info("Just before finding element " + arg1.toString());

    }

    public void beforeNavigateBack(WebDriver arg0) {
        // TODO Auto-generated method stub
        log.info("Just before beforeNavigateBack " + arg0.getCurrentUrl());

    }

    public void beforeNavigateForward(WebDriver arg0) {
        // TODO Auto-generated method stub
        log.info("Just before beforeNavigateForward " + arg0.getCurrentUrl());

    }

    public void beforeNavigateTo(String arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("Just before beforeNavigateTo " + arg0);
    }

    public void beforeScript(String arg0, WebDriver arg1) {
        // TODO Auto-generated method stub
        log.info("Just before beforeScript " + arg0);
    }

    public void onException(Throwable arg0, WebDriver arg1) {
        log.info("Exception occured at " + arg0.getMessage());

    }

    public void afterNavigateRefresh(WebDriver arg0) {
        // TODO Auto-generated method stub

    }

    public void beforeNavigateRefresh(WebDriver arg0) {
        // TODO Auto-generated method stub

    }

}

接下来我们需要在脚本中使用它，如下所示：

@BeforeClass()
    public void signIn() throws Exception
        {

        BasicConfigurator.configure();
        PropertyConfigurator.configure(PROPERTIES_FILEPATH);

        log = Logger.getLogger("SuperTest");

        //Delete the test-output directory
        try
        {
        FileUtils.deleteDirectory(new File("./test-output"));
        }
        catch(Exception e)
        {

        }

        //Get the Browser Type and initiate the Driver
        driver = GenericUtilLibrary.initializeBrowser(driver, BROWSER_TYPE);
        driver.manage().deleteAllCookies();
        driver.manage().timeouts().implicitlyWait(40, TimeUnit.SECONDS);
        driver.manage().window().maximize();

        //create a object for EventFiringWebDriver Class
        eventDriver = new EventFiringWebDriver(driver);

        //create object of the class (EventHandler) which implemented WebDriverEventListener Interface. 
        handler = new EventHandler();

       //register handler object with EventFiringWebDriver
        eventDriver.register(handler);


        eventDriver.get(URL);


        //CLICK ON SIGNIN BUTTON IN LOGIN PAGE.
        LoginPage lpage = new LoginPage(driver);
        lpage.clickSignInButton();


        //ENTER USER CREDENTIALS AND CLICK ON SIGNON BUTTON IN SIGNIN PAGE.
        SignInPage spage = new SignInPage(driver);
        spage.clickSignInButton(USERNAME, PASSWORD);
    }

一旦注册，当我们对所有WebElements使用eventDriver时，eventDriver将处理记录WebDriver的操作。

直到eventDriver.get（URL）;我没有问题但是当谈到下一步时，我正在调用Object Page Classes并调用它们的方法。要发送eventDriver而不是驱动程序对象，我在调用第一个方法本身时会收到NULLPOINTEREXCEPTION。

我不知道如何使用WebDriverEventListener。

请任何人帮助我。

在您的代码中，您有一个简单的错误。

代替：

 //CLICK ON SIGNIN BUTTON IN LOGIN PAGE.
        LoginPage lpage = new LoginPage(driver);
        lpage.clickSignInButton();

您应该使用：

 //CLICK ON SIGNIN BUTTON IN LOGIN PAGE.
        LoginPage lpage = new LoginPage(handler);
        lpage.clickSignInButton();

问题出在WebDriverEventListener类中，而不是初始化每个类的构造函数。有了@Denis的建议它会起作用。在WebDriverEventListener类中，错误的是beforeFindBy

public void beforeFindBy(By arg0, WebElement arg1, WebDriver arg2) {
    // TODO Auto-generated method stub
    log.info("Just before finding element " + arg1.toString());

}

它应该是

public void beforeFindBy(By arg0, WebElement arg1, WebDriver arg2) {
    // TODO Auto-generated method stub
    log.info("Just before finding element " + arg0);

}

我在配置WebDriverEventListener和我的项目时也遇到了同样的问题。我确实通过传递EventFiringWebDriver对象而不是驱动程序来弄清楚。而且，瞧，它很棒！

    public static EventFiringWebDriver eventFiringWebDriver;
    public static WebDriverEventListener webDriverEventListener;
    eventFiringWebDriver= new EventFiringWebDriver(driver);
    webDriverEventListener= new WebEventListener();
    eventFiringWebDriver.register(webDriverEventListener);

    LoginPage lpage = new LoginPage(eventFiringWebDriver);

如何在页面工厂模式中使用WebDriverEvent侦听器
