PageFactory.InitElements with Selenium 4-CodePudding

I want to update my legacy project selenium library to newest. Unfortunately I am facing problems with PageFactory.InitElements method (which is by default unavailable in Selenium 4, but available in DotNetSeleniumExtras.PageObjects). This is my example code:

class Program
{
    static void Main(string[] args)
    {
        var options = new FirefoxOptions();
        options.BrowserExecutableLocation = @"C:\Program Files\Mozilla Firefox\firefox.exe";

        var firefoxDriverService = FirefoxDriverService.CreateDefaultService("d:\\gecko");
        firefoxDriverService.HideCommandPromptWindow = true;

        var driver = new FirefoxDriver(firefoxDriverService, options);
        driver.Navigate().GoToUrl("SITE_URL");

        var loginPage = new LoginPage(driver);
        loginPage.EnterLogin("foo");
    }
}

public class LoginPage
{
    public IWebDriver Driver { get; private set; }

    [FindsBy(How = How.XPath, Using = "//input[contains(@id,'login_btn')]")]
    public IWebElement LoginTextField { get; protected set; }

    public LoginPage(IWebDriver driver)
    {
        Driver = driver;
        PageFactory.InitElements(Driver, this);
    }

    public void EnterLogin(string login)
    {
        LoginTextField.SendKeys(login);
    }
}

If I run this, I am getting error on PageFactory.InitElements line:

System.TypeLoadException: Could not load type 'OpenQA.Selenium.Internal.IWrapsElement' from assembly 'WebDriver, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'

If I change packages configuration from:

DotNetSeleniumExtras.PageObjects 3.11.0
Selenium.WebDriver 4.1.0

to:

DotNetSeleniumExtras.PageObjects 3.11.0
Selenium.WebDriver 3.141.0

It works fine. Seems like a new version of Selenium doesn't like legacy PageFactory.InitElements. Is there anything I can do about it? I would like to have my page object classess as they are right now, because there are many of them.

CodePudding user response：

maybe this will solve your problem. The import is as follows:


import org.openqa.selenium.support.PageFactory;

And Page Factory initialisation is as follows (I have configured it so you can just copy/paste it) :

public LoginPage (){
        PageFactory.initElements(driver, this);
    }

CodePudding user response：

you cannot use PageFactory class and FindsBy attribute to store element when you use selenium version 4.1.0, instead create as a property for IWebElement/By type and it resolves this issue,I hope this solves your issue. Link to similar issue
