为什么我不能在我的 TestNg 中使用 Page Factory class

Question

我尝试在我的代码中使用 @FindBy，但它不起作用

这是 PageObjectModel class

package Support;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.How;

public class LoginPom {

    WebDriver driver;

    public LoginPom(WebDriver driver) {

        this.driver=driver;
    }

    @FindBy(how=How.XPATH,using="//*[@id=\"input-email\"]")
    WebElement txtEmail;

    @FindBy(xpath="//*[@id=\"input-password\"]")
    WebElement txtPassword;

    @FindBy(xpath="//*[@id=\"content\"]/div/div[2]/div/form/input")
    WebElement submitLogin;

public void loginAccount(String email,String password) {

        txtEmail.sendKeys(email);

        txtPassword.sendKeys(password);

        submitLogin.click();
        }
}

这是 TestNG class

package Support;

import org.testng.annotations.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.PageFactory;
import org.testng.annotations.BeforeMethod;

public class TestDemoPage {

      WebDriver driver;

  @Test()
  public void TestCase_1() {

     LoginPom loginPom=PageFactory.initElements(driver,LoginPom.class);

      loginPom.loginAccount("user@mail.com", "password");

  }


  @BeforeMethod
  public void openBrowser() {
      String exePath="C:\chromedriver.exe";

      System.setProperty("webdriver.chrome.driver",exePath);

      driver= new ChromeDriver();

      driver.manage().window().maximize();

      driver.get("https://demo.opencart.com/index.php?route=account/login");  
  }
}

我得到的例外是

谢谢，帮助我解决这个问题并正确使用 PageFactory

Answer 1

我建议在页面对象本身内调用页面工厂（或者理想情况下创建一个基础 class 并在那里执行）：

public LoginPom(WebDriver driver) {
    this.driver=driver;
    PageFactory.initElements(driver, this);
}

然后将您的测试对象初始化为：

LoginPom loginPom = new LoginPom(driver);

Answer 2

尝试添加包含驱动程序、服务员声明和调用初始化程序的抽象 class。在服务员（流利的等待）中添加 pagefactory.initelements()。让所有 POM 扩展到抽象 class 之上以获得相同的驱动程序。
