JAVA通过TestNG selenium automation打开另一个页面时lang.ExceptionInInitializeError

Question

我使用了两页的POM模型。登录页

PS.它是工作正常，如果返回类型被更改为无效的验证登录（）.

参考BaseTest。

public class BaseTest 
{
    public static WebDriver driver ;
    public static String chrome_path ="/home/downloads/chromedriver";
   public static String property_file_path ="/home/CompleteMotorJourneyAutoTest/src/test/java/com/qa/utils/loginDetails.properties";
    
    public BaseTest()
    {
        try {
            FileInputStream fis = new FileInputStream(property_file_path);
            Properties prop = new Properties();
            prop.load(fis);         
            }catch(Exception e) {System.out.println("Exception occured during reading the property file !");}
    }
    
    public static void initialization() 
    {           System.setProperty("webdriver.chrome.driver",chrome_path);
                driver=new ChromeDriver();          
        driver.get(prop.getProperty("URL"));
    }
}

登录页

public class LoginPage extends BaseTest
{
    @FindBy(xpath="//*[@id=\"loginform\"]/div[1]/div[2]/input")
    WebElement email_id_field;
    @FindBy(xpath="//*[@id=\"loginform\"]/div[2]/div[2]/input")
    WebElement password_field;
    @FindBy(xpath="//*[@id='loginform']/input")
    WebElement login_button_Field;

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

    public HomePage verifyLogin(String username,String password) 
    {   email_id_field.sendKeys(username);
        password_field.sendKeys(password);
        login_button_Field.click();
        return new HomePage();
    }
}

登录测试

public class LoginTest extends BaseTest 
{   LoginPage loginpage;
    HomePage homepage;  

    public LoginTest() 
    {   super();    }

    //Browser initialization/Environment setup  <----------------------
    @BeforeMethod                               
    public void setup() 
    {   initialization();
        loginpage = new LoginPage();    }

    //login with correct credentials            <----------------------
    @Test(priority=0)
    public void loginWithCorrectCredentials() 
    {       homepage=loginpage.verifyLogin(prop.getProperty("login_id"),prop.getProperty("login_password")); 
    }
    
    //Browser closure                           <----------------------
    @AfterMethod
    public void tearDown()
    {   driver.quit();      }
}

我也需要测试一下主页，但自从得到它后就被卡住了

有人能帮忙吗。提前感谢！

关门了。问题在于主页。具有XPath的java类
