Java Selenium - in separate Class method is working, in POM - NullPointerException

I spent two days on this, and can't seem to find where is the error. In a separate Class, the code is working. In pom.xml I get an error: NullPointerException: Cannot invoke LoginPage.loginCustomer() because this.loginPage is null.
public class _BasePage {
private WebDriver driver;
private WebDriverWait driverWait;
}
with parametrised construktor, getters and setters. Then, a class BankManagerMenu:
public class BankManagerMenu extends _BasePage {
private By addCustomer = By.xpath("/html/body/div/div/div[2]/div/div[1]/button[1]");
public BankManagerMenu(WebDriver driver, WebDriverWait driverWait){
super(driver,driverWait);
}
public boolean addCustomerBtn(){
return this.getDriver().findElement(this.addCustomer).isDisplayed();
}
And a Class LoginPage
public class LoginPage extends _BasePage {
private By customerButton = By.xpath("//*[contains(text(), 'Customer Login']");
private By bankManagerButton = By.xpath("//*[contains(text(), 'Bank Manager Login')]");
public LoginPage(WebDriver driver, WebDriverWait driverWait) {
super(driver, driverWait);
}
public void loginBankManager() {
new WebDriverWait(getDriver(), Duration.ofSeconds(20)).until(ExpectedConditions.elementToBeClickable(bankManagerButton)).click();
}
public void loginCustomer() {
this.getDriver().findElement(this.customerButton).click();
}}
Finally, this is my Test Class
public class TestPage {
private WebDriver driver;
private WebDriverWait driverWait;
private LoginPage loginPage;
private BankManagerMenu bankManagerMenu;
public TestPage(){}
#BeforeClass
public void beforeClass(){
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Raven\\Desktop\\QA\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
// WebDriverWait driverWait = new WebDriverWait(driver, Duration.ofSeconds(15));
driver.navigate().to("https://www.globalsqa.com/angularJs-protractor/BankingProject/#/login");
}
#Test
public void loginAsBankManager(){
this.loginPage.loginBankManager();
// Assert.assertTrue(this.bankManagerMenu.addCustomerBtn());
}}

Multiple instances of browser opening up when running test through webdriver manager

I am new to Selenium, so basically whenever I ran my test, it would open up the URL which I have mentioned in my test. In my same Test I have also mentioned to fill the username and Password.
But somehow once the browser gets launched and redirect to the URL, it opens up another instance of blank browser failing my script that element not found.
Please help me here.

Each call to the truefill() method initializes a new instance of WebDriver. Since your test is calling it multiple times, it will start a new browser instance on each line. Instead, store the DashboardPage in a local variable:
#Test
public void userLoginIntoTheSystem() {
DashBoardPage dashBoardPage = truefill().dashBoard();
dashBoardPage.Url();
dashBoardPage.EnterUsername("bjdgfe#swcwr.com");
dashBoardPage.EnterPassword("Test1234");
}
You might also want to use a setup method to initialize the Truefill instance, rather than creating it on demand:
private Truefill truefill;
#BeforeEach
public void initializeTruefill() {
WebDriver driver = InitializeDriver();
truefill = new Truefill(driver);
}
#Test
public void userLoginIntoTheSystem() {
DashBoardPage dashBoardPage = truefill.dashBoard();
dashBoardPage.Url();
dashBoardPage.EnterUsername("bjdgfe#swcwr.com");
dashBoardPage.EnterPassword("Test1234");
}
This assumes JUnit 5. If you're using JUnit 4, the annotation is #Before instead of #BeforeEach.

NoSuchElementException using WebDriverWait

I would really like to understand why when approaching locating an element the exact same way as previously failing.
NoSuchElementException : Caused by: org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//span[contains(text(),'Add')]"}
I have also tried to use something like the following but it also failed, so in order for me write a good automation code i need to get my knowledge straight with WebDriverWait, so i would appreciate somebody with knowledge to spend some time on this inquiry.
It does locates if i have xpath like this :
//body/div[#id='root']/div[1]/div[1]/div[1]/div[2]/div[1]/div[1]/div[2]/div[1]/div[2]/div[1]/div[2]/div[1]
public void clickOnAddVehicleButton() {
wait.until(ExpectedConditions.visibilityOf(addVehicleButton));
vehicles.addVehicleButton.click();
}
I am not new into Java but i am new into automation hence some areas of knowledge is missing, i ha
Base class:
public class BasePage {
protected final WebDriver driver;
protected final WebDriverWait wait;
public BasePage(WebDriver driver) {
this.driver = driver;
this.wait = new WebDriverWait(driver,5);
PageFactory.initElements(new AjaxElementLocatorFactory(driver, 10), this);
}
}
The component where that button should be present :
public class Vehicles extends BasePage {
private static Vehicles vehicles;
private Vehicles(WebDriver driver) {
super(driver);
}
#FindBy(xpath = "//span[text(),'Add']")
public WebElement addVehicleButton;
public static Vehicles vehiclesInstance(WebDriver driver) {
return vehicles == null ? vehicles = new Vehicles(driver) : vehicles;
}
public void clickOnAddVehicleButton() {
vehicles.addVehicleButton.click();
}
Function in the service class:
public void addVehicle(String vehicleName, String numberPlate) {
myAccountService.myAccountPage()
.clickOnVehiclesTab();
vehicles.fillInVehicleName(vehicleName)
.fillInVehicleNumberPlate(numberPlate)
.clickOnAddVehicleButton();
}
WebDriverSettings for test :
public class WebDriverSettings {
protected WebDriver driver;
#Before
public void setUp() {
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
loginToDevEnvironment();
}
And finally my test class where i am calling the service method:
public class VehicleServiceTest extends WebDriverSettings {
private VehiclesService vehiclesService;
#Before
public void setUp(){
super.setUp();
CookieService.cookieServiceInstance(driver).acceptCookies();
HomePageService.homePageServiceInstance(driver).clickOnMyAccountTab();
LoginService.loginServiceInstance(driver).login(loginCorrectData());
HomePageService.homePageServiceInstance(driver).clickOnMyAccount();
vehiclesService = VehiclesService.vehiclesServiceInstance(driver);
}
#Test
public void shouldAddVehicle(){
vehiclesService.addVehicle("test-vehicle","test-test");
Assert.assertEquals(1,vehiclesService.getVehicles().listOfAddedVehicles().size());
}

How to use the same Webdriver from different class

I have 2 Java classes; Main.java and Methods.java. At Main.java, I initialize the chrome webdriver and I want to use the same webdriver for a method at Methods.java. Below are the codes.
Under Main.java
Methods getMethods = new Methods();
#BeforeTest
public void Setup()
{
System.setProperty("webdriver.chrome.driver", "C:\\...\\chromedriver.exe");
driver = new ChromeDriver();
driver.get(PropertiesConfig.getObject("websiteUrl"));
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
#Test
public void TestCase1()
{
getMethods.method1();
}
#AfterTest
public void QuitTC() {
getMethods.QuitTC(); }
Under Methods.java
public void method1 (){
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
….. }
public void QuitTC() {
driver.quit();
}
My question is how do I called the initialize Webdriver from Main.java and used it at Methods.java?
Any help with be appreciated! Thanks!

You can do something like this in a utility class (say TestUtil.java)
private static WebDriver wd;
public static WebDriver getDriver() {
return wd;
}
and then you can use following line to get the webdriver in any of the classes mentioned and work on it
WebDriver driver = TestUtil.getDriver();

Declare a global variable for driver like this :
WebDriver driver = null;
#BeforeTest
public void Setup()
{
System.setProperty("webdriver.chrome.driver", "C:\\...\\chromedriver.exe");
driver = new ChromeDriver();
driver.get(PropertiesConfig.getObject("websiteUrl"));
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
Now, you can call method1 from method class like this :
public class Methods{
public Methods(WebDriver driver){
this.driver = driver;
}
public void method1 (){
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
….. }
}
Now once you create the instance of Methods class, constructor would be called and driver reference could be passed.

Try this
Class1 {
public WebDriver driver = null;
public String baseURL="...";
public void openURL() {
System.setProperty("webdriver.chrome.driver", "D:...\\chromedriver.exe");
driver = new ChromeDriver();
driver.get(baseURL);
}
Class2 extends Class1 {
driver.findElement(....);
}

WebDriver - one instance of driver in many classes

I have 3 classes like below but when I try to run my test I get NullPointer (TestPage->input1). On debug I spotted that I have a second instantion of driver which is null. Can anyone help me what I did wrong and how to fix it? Shouldn't it work properly?
public class BaseScenario {
protected WebDriver driver;
#BeforeMethod
public void setUp() throws Exception {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Ed\\Desktop\\chromedriver.exe");
driver = new ChromeDriver();
driver.get("http://toolsqa.com/automation-practice-form/");
}
#AfterMethod
public void TearDown() {
driver.quit();
}
}
'
public class TestsPage {
WebDriver driver;
public TestsPage(WebDriver driver)
{
this.driver=driver;
}
public void input1(){
driver.findElement(By.xpath("//*[#id='content']/form/fieldset/div[1]/input[1]")).sendKeys("Kuba");;
}
public WebElement input2(){
WebElement input2 = driver.findElement(By.xpath("//*[#id='content']/form/fieldset/div[1]/input[2]"));
return input2;
}
}
'
public class Tests extends BaseScenario{
TestsPage pagee = new TestsPage(driver);
#Test
public void TC1() throws Exception {
pagee.input1();
pagee.input2().sendKeys("Chudy");
}
}
