Question

我实现了一个单独的PageFactory BasePage类，用于保存测试页面的碎片。我在BasePage中为WebDriver驱动程序引用

创建了一个构造函数

import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class BasePage {
  WebDriver driver;

public BasePage(WebDriver driver) {      //constructor
    this.driver = driver;
  }


@FindBy(xpath = "path")
public WebElement id;
@FindBy(xpath = "path")
public WebElement password;
@FindBy(xpath = "path")
public WebElement signIn;

然后我在测试类中初始化了BasePage类，这样：BasePage basePage = PageFactory.initElements(driver, BasePage.class);初始化不会引发错误。

import org.testng.annotations.Test;

public class Active {
public static WebDriver driver;
private final BaseUtil baseUtil = new BaseUtil();
BasePage basePage = PageFactory.initElements(driver, BasePage.class); //Initialisation


@Test
public void navigateToUrl() throws InterruptedException {
ChromeDriverManager.getInstance().setup();
driver = new ChromeDriver()
driver.get(baseUtil.getUrl());

basePage.id.click();
basePage.id.sendKeys("0000");
basePage.password.click();
basePage.password.sendKeys("admin");
basePage.signIn.click();

}

我运行了测试，但无法执行，抛出NullpointerException：

有没有人知道我在使用PageFactory与我的测试类同步时做错了什么？

Answer 1

初始化驱动程序后，在测试方法中移动BasePage初始化。基本上，当前代码中的驱动程序为空。
