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());
}

Page object in testng error (java.lang.NullPointerException) [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 4 years ago.
I'm trying to implement the concept of Page Object using TestNG. I created a BrowserFactory class that has the information to initialize the browser.
I also created a class called LogSystemPage that has the information of the screen elements that I need to interact with.
Lastly, I created a test class called ValidateStatusTestNG that "calls" the BrowserFactory and LogSystemPage classes.
When I try to run the test method called logarSystem, the Eclipse console displays the following error message: java.lang.NullPointerException.
Following is the code, the error message and the images.
public class BrowserFactory {
static WebDriver driver;
public static WebDriver startBrowser(String url) {
System.setProperty("webdriver.chrome.driver", "E:\\Selenium\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get(url);
return driver;
}}
public class LogarSistemaPage {
private static WebDriver driver;
public WebDriver logarSistema(WebDriver driver) {
driver.findElement(By.id("matricula_I")).sendKeys("844502");
driver.findElement(By.id("senha_I")).sendKeys("Pw34Jdt#*");
driver.findElement(By.id("bt_entrar")).click();
return driver;
}}
public class ValidarStatusTestNG {
static WebDriver driver;
#BeforeClass
public void setUp() throws Exception {
BrowserFactory b = new BrowserFactory();
b.startBrowser("http://10.5.9.45/BKOMais_S86825EstrategiaBackOfficeClaroFixo/");
}
#Test
public void logarSistema(){
LogarSistemaPage s = new LogarSistemaPage();
s.logarSistema(driver);
}
#AfterClass
public static void closeBrowser() {
//driver.quit();
}}

driver =b.startBrowser("http://10.5.9.45/BKOMais_S86825EstrategiaBackOfficeClaroFixo/")
You need to assign the return value of method returning driver to driver.
#BeforeClass
public void setUp() throws Exception {
BrowserFactory b = new BrowserFactory();
driver =b.startBrowser("http://10.5.9.45/BKOMais_S86825EstrategiaBackOfficeClaroFixo/");
}
#Test
public void logarSistema(){
LogarSistemaPage s = new LogarSistemaPage();
s.logarSistema(driver);
}
That should do the work.

java.lang.NullPointerException Selenium 2 classes

My program works fine when run from my local machine with out using selenium grid with Remote Web driver. However when i set up the same test cases using selenium grid with Remote Web driver . Get message in eclipse saying:
java.lang.NullPointerExceptionat PP_OBJ_Login.Adminlogin(PP_OBJ_Login.java:38)
at PP_Main.step01_Login(PP_Main.java:86)
Now I know the above means that line 38 and line 86 is where the problem is in both classes my problem is i don't know why this is happening when I use selenium grid with Remote Web driver.
public class PP_Main {
private static WebDriver driver;
private static String homeUrl;
//private String homeTitle ="Google";
#SuppressWarnings("unused")
private boolean acceptNextAlert = true;
private static StringBuffer verificationErrors = new StringBuffer();
#BeforeClass
public static void setUp() throws Exception {
//----------This works and envokes IE browser -------
System.setProperty("webdriver.ie.driver", "C:\\IEDriverServer.exe");
DesiredCapabilities cap = DesiredCapabilities.internetExplorer();
cap.setCapability(CapabilityType.BROWSER_NAME, DesiredCapabilities.internetExplorer());
cap.setBrowserName("internet explorer");
cap.setPlatform(Platform.ANY);
RemoteWebDriver driver = new RemoteWebDriver(new URL("http://51.19.210.111:5555/wd/hub"), cap);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
String url = "https://wfn-iat.adp.com/public/index.htm";
driver.get(url);
}
#Test
public void step01_Login() throws Exception {
PP_OBJ_Login.AdminVisiable(driver);
PP_OBJ_Login.Adminlogin(driver).click();-- -> line 86
PP_OBJ_Login.UserName(driver).sendKeys("NorfolkAutoUser6#adp");
PP_OBJ_Login.Submitbtn(driver).click();
PP_OBJ_Login.Password(driver).sendKeys("iatiat01");
Thread.sleep(2000);
PP_OBJ_Login.Submitbtn(driver).click();
Thread.sleep(5000);
}
PP_OBJ_Login.Java
public class PP_OBJ_Login {
private static WebElement element = null;
// WebElement Adminlogin
public static WebElement Adminlogin(WebDriver driver) {-- -- -> Line 38
element = driver.findElement(By.id("adminLogin"));
return element;
}
// WebElement input Field
public static WebElement UserName(WebDriver driver) {
element = driver.findElement(By.id("USER"));
return element;
}
I want this to work using selenium grid and remote web driver. Is there any way to resolve the null pointer issue?

Your Problem is, that you define 'driver' as a class member but you do not instantiate it. So it is null all the time.
public class PP_Main {
private static WebDriver driver;
private static String homeUrl;
//...
And the driver you instantiate inside setUp() is only valid inside the method itself. Although it has exactly the same name it is NOT the 'driver' you defined globally.
#BeforeClass
public static void setUp() throws Exception {
// ...
cap.setPlatform(Platform.ANY);
RemoteWebDriver driver = new RemoteWebDriver(new URL("http://51.19.210.111:5555/wd/hub"), cap);
// ...
}
Instantiate it this way instead
public class PP_Main {
private static RemoteWebDriver driver;
private static String homeUrl;
//...
#BeforeClass
public static void setUp() throws Exception {
// ...
cap.setPlatform(Platform.ANY);
driver = new RemoteWebDriver(new URL("http://51.19.210.111:5555/wd/hub"), cap);
// ...
}
This should work.

Using Common Selenium WebDriver instance

I want use a common WebDriver instance across all my TestNG tests by extending my test class to use a base class as shown below but it doesn't seem to work :
public class Browser {
private static WebDriver driver = new FirefoxDriver();
public static WebDriver getDriver()
{
return driver;
}
public static void open(String url)
{
driver.get(url);
}
public static void close()
{
driver.close();
}
}
I want to use the WebDriver in my test class as shown below, but I get the error message :
The method getDriver() is undefined for the type GoogleTest:
public class GoogleTest extends Browser
{
#Test
public void GoogleSearch() {
WebElement query = getDriver().findElement(By.name("q"));
// Enter something to search for
query.sendKeys("Selenium");
// Now submit the form
query.submit();
// Google's search is rendered dynamically with JavaScript.
// Wait for the page to load, timeout after 5 seconds
WebDriverWait wait = new WebDriverWait(getDriver(), 30);
// wait.Until((d) => { return d.Title.StartsWith("selenium"); });
//Check that the Title is what we are expecting
assertEquals("selenium - Google Search", getDriver().getTitle().toString());
}
}

The problem is that your getDriver method is static.
Solution #1: Make method non-static (this will either need to make the driver variable non-static as well, or use return Browser.getDriver(); )
public WebDriver getDriver() {
return driver;
}
Or, call the getDriver method by using Browser.getDriver
WebElement query = Browser.getDriver().findElement(By.name("q"));

You need to start your driver, one of many solution is to try #Before to add, Junit will autorun it for you.
public class Browser {
private WebDriver driver;
#Before
public void runDriver()
{
driver = new FirefoxDriver();
}
public WebDriver getDriver()
{
return driver;
}
public void open(String url)
{
driver.get(url);
}
public void close()
{
driver.close();
}
}
