java.lang.ExceptionInInitializerError while opening another page through TestNG selenium automation

I've used POM model with 2 pages . LoginPage & HomePage . these 2 pages has 2 test classes (LoginTest & HomeTest) along with BaseTest(Driver initialization purposes & being inherited by all 4 classes) . While clicking loginpage.verifyLogin(email_id , pswrd) , the homepage is supposed to be opened . I'm getting java.lang.ExceptionInInitializerError while executing login testcase.
PS. It is working fine if return type is changed to void for verifyLogin().
Refer the 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"));
}
}
LoginPage
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();
}
}
LoginTest
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(); }
}
I need to test Homepage as well but stuck since getting

Can anyone please help . Thanks in advance !

It's closed. Issue was with HomePage.java class which has the xpaths & methods for HomeTest.java class. The HomePage.java class had static WebElements which had incorrect xpaths. Now , corrected the xpaths & found it working fine .

Unable to initialise using #FindBy in selenium webdriver java

I am trying to perform basic selenium operations using page object pattern. However, when I run the test, I see browser being opened along with given url, but fails the test by complaining it couldn't initialise the declared web element. Can some one please help me to understand what I'm missing here. Below are my base class, page object class and test class.
BasePage
public class Basepage {
public static WebDriver driver;
public Basepage(){}
public Basepage(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver,this);
}
public void OpenBrowser(){
System.setProperty("webdriver.chrome.driver",
"C:\\SeleniumWork\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.navigate().to("https://www.google.com");
}
Page object class
public class SecurityMainPage extends Basepage{
public SecurityMainPage(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver,this);
}
#FindBy( xpath = "//a[text()='What We Do']")
WebElement dropdown;
public void selectOption(String option){
Actions actions = new Actions(driver);
actions.moveToElement(dropdown).click().build().perform(); //dropdown element is returning null
}
TestClass
public class SecurityMainPageTests extends Basepage {
protected static SecurityMainPage sec = new SecurityMainPage(driver);
public SecurityMainPageTests(){}
#BeforeTest
public void setup(){
OpenBrowser();
}
#Test

For easy understanding, I split the driver initiation and navigation to url to two methods in Basepage. And you haven't declared the closeBrowser() method.
Base Class
public class Basepage {
public static WebDriver driver;
public Basepage(){}
public Basepage(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver,this);
}
public WebDriver initiateDriver(){
System.setProperty("webdriver.chrome.driver",
"C:\\SeleniumWork\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
return driver;
}
public void openBrowser(String url){
driver.navigate().to(url);
}
}
Test Class
public class SecurityMainPageTests extends Basepage {
WebDriver driver = null;
protected static SecurityMainPage sec = null;
String url = "https://www.google.com";
public SecurityMainPageTests(){}
#BeforeTest
public void setup(){
driver = initiateDriver();
openBrowser(String url);
sec = new SecurityMainPage(driver);
}
#Test
public void selectOptionTest(){
sec.selectOption("Networking");
}
#AfterTest
public void tearDown(){
closeBrowser();
}
}

"org.openqa.selenium.WebDriverException" Error displayed in the code

I am unable to find what is the cause of the error "org.openqa.selenium.WebDriverException" in my code, Please help me find and understand the cause much better. Firstly I would like to explain my code, It is a simple code where I go to a website click on "Sign In" link and then click on a text "Email" text field for registration purpose. I have used Page Factory in this code.
I have 3 files.
- Base file (Before and After methods)
- Registration File (Object repository and methods)
- Registration_Testcase File (Calling the methods)
Note: Base and Registration Testcase classes are in one package and Registration is in another package.
**Below is my code:**
Base Class
package testcases;
import org.testng.annotations.BeforeTest;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.firefox.internal.ProfilesIni;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.AfterTest;
public class Base {
public WebDriver driver;
public WebDriverWait wait;
#BeforeTest
public void beforeTest() {
ProfilesIni pro = new ProfilesIni();
FirefoxProfile ffProfile = pro.getProfile("vishvesh");
ffProfile.setAcceptUntrustedCertificates(true);
ffProfile.setAssumeUntrustedCertificateIssuer(false);
String base_url = "http://automationpractice.com/index.php";
System.setProperty("webdriver.gecko.driver", "G:/Workplace/AutomationSetupFiles/Geckdriver/geckodriver.exe");
driver = new FirefoxDriver();
driver.get(base_url);
}
#AfterTest
public void afterTest() {
driver.close();
}
}
Registration Class
package pages;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.ExpectedConditions;
import testcases.Base;
public class Registration extends Base{
#FindBy(xpath="//*[#id='header']/div[2]//div[1]/a")
WebElement SignIn;
#FindBy(xpath="//input[#id='email_create']")
WebElement Registration_Email;
public Registration(WebDriver driver){
this.driver=driver;
PageFactory.initElements(driver, this);
}
public void ClickSignIn(){
//wait.until(ExpectedConditions.visibilityOf(SignIn)).click();
SignIn.click();
}
public void EnterEmail(String y){
//wait.until(ExpectedConditions.visibilityOf(Registration_Email)).click();
Registration_Email.click();
Registration_Email.sendKeys(y);
}
}
Registration TestCase Class
package testcases;
import org.testng.annotations.Test;
import pages.Registration;
public class Registatration_testcase extends Base{
#Test
public void f() {
Registration regobj = new Registration(driver);
regobj.ClickSignIn();
regobj.EnterEmail("amdv1991#gmail.com");
}
}

You haven't set capabilities platformName, platformVersion,app and deviceName. You're testing Android app, so You need to provide additionally capabilites appActivity and appPackage.

DesiredCapabilities caps = new DesiredCapabilities();
caps.SetCapability("app-package", "com.myapp.test");
caps.SetCapability("browserName", "");
caps.SetCapability("device", "Android");
caps.SetCapability("app-activity", "com.myapp.SplashActivity");
caps.SetCapability("version", "4.1.2");
caps.SetCapability("device ID", "uniquedeviceid");
caps.SetCapability("app", "apk-path");
To narrow down your issue, please provide your testng.xml file.

the problem is located on the command driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);.
Can anyone please tell me why this is happening?

NoSuchfield exception is thrown if an application tries to access or modify a specified field of an object, and that object no longer has that field. If this error is happening at the Android driver instantiation, then it could be that some of capabilites you have may not be right. There is no such capability as appium-version - Link. Also device_name is ignored for Android. Try out below capabilities
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME,
"Selendroid");
capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
capabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, "4.3");
capabilities.setCapability(MobileCapabilityType.APP_PACKAGE: "wizzo.mbc.net");
capabilities.setCapability(MobileCapabilityType.APP_ACTIVITY: "wizzo.mbc.net.activities.SplashActivity");
