Question

我尝试在代码中使用@FindBy，但它无效

这是PageObjectModel类

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类

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，帮助我解决此问题并正确使用PageFactory

Answer 1

我建议在页面对象本身内调用页面工厂（或理想情况下创建基类并在那里执行）：

raw_input()

然后将测试对象初始化为：

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

Answer 2

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

为什么我不能在TestNg类中使用Page Factory
