#BeforeTest doesn't run for all the #Test, only before the first one, so driver is never initialized. From testng docs
#BeforeTest: The annotated method will be run before any test method belonging to the classes inside the <test> tag is run.
You can use #BeforeMethod annotation for that
#BeforeMethod: The annotated method will be run before each test method.
Same goes for #AfterTest and #AfterMethod.

I've run into the following error."Cannot instantiate class co.edureka.tests.FBLoginTest". Below I've posted the entire error console. I'm trying to use POM (Page Obeject Model) for Selenium. I'm believe the issue has to do with me creating too many drivers... I've been digging through online resources, but haven't found anything that resolves my issue.

If anyone has any suggestions I would appreciate it.
To solve this issue you should move the WebDriverWait initialization to the init or any other method in FBLoginTest.java like below.

#BeforeMethod
public void init() {
wait = new WebDriverWait(driver, Duration.ofSeconds(30));
}
#Test
public void testLogin() throws Exception {
driver.get("https://www.facebook.com");
FBLoginPage loginpage = PageFactory.initElements(driver, FBLoginPage.class);
wait.until(ExpectedConditions.titleContains("Facebook"));
loginpage.setEmail("432547#gmail.com");
loginpage.setPassword("ashish.bakshi#selenium");
loginpage.clickOnLoginButton();
FBHomePage homepage = PageFactory.initElements(driver, FBHomePage.class);
homepage.clickOnProfileDropdown();

===============================================
Please help, I'm not sure why the webelement is not identified. I tried with other web elements and they also get the same NPE.
The problem lies in your test code.
The WebDriver object that is part of your base class BaseClass1 is getting initialised only when the method launchApp() is invoked.
But the constructor of your page class IndexPage1 already tries to access the WebDriver object (which at the time of instantiation of IndexPage1 is null)
So you end up invoking PageFactory.initElements(driver, this); with a null value for driver
Solution.
Please remove the logic of managing your webdriver instances via your base class and segregate it to a separate utility method which when called can give you a WebDriver object. Alternatively you can also make use of a library such as Autospawn that I created which uses an annotation way of managing webdriver instances. - The documentation should explain how to use this library. Note that if you use this library, you would need to create all your page classes within your #Test method (because that's the only place wherein a valid WebDriver instance would be available in the current Thread's context)
Refactor your IndexPage1 class's constructor so that it accepts a WebDriver instance as a parameter from outside.
I have implemented simple Login selenium framework using DataProvider.
I created a simple login page which contains username and password. I have also created excel file with login data and excel reader class as well. Seems that DataProvider within my test class fault.
I get the the information "java.lang.NullPointerException".I know that is something wrong with String in DataProvider, but if I changed to Object the issue is still as above.
Here is my code for testng:

lp.setUserName(user);
lp.setPassword(pwd);
lp.clickSubmit();
if (isAlertPresent()==true){
driver.switchTo().alert().accept();
driver.switchTo().defaultContent();
Assert.assertTrue(false);
}
else {
Assert.assertTrue(true);
lp.clickLogout();
driver.switchTo().alert().accept();
driver.switchTo().defaultContent();
}
}
public boolean isAlertPresent(){
try {
driver.switchTo().alert();
return true;
}
catch (NoAlertPresentException e){
return false;
}

for (int j=0;j<colcount;j++){
logindata[i-1][j]=excelReader.getCellData(path,"DataSet",i,j);
}
}
return logindata;
}
}

The root cause of your problem is in your base class.
You are initialising/cleaning a WebDriver object via the Unit provided Before and After.
TestNG does not recognise JUnit setup and teardown annotations
To fix this problem, all you would need to do is to use
Instead of Before use org.testng.annotations.BeforeClass (or) BeforeMethod
Instead of After use org.testng.annotations.AfterClass (or) AfterMethod
I suspect your baseUrl seems to be empty based on NPE at line 17 of TC_LoginDdt_002. Run in Debug mode to ensure your public String baseUrl = readconfig.getApplicationUrl(); is actually retrieving and initializing the baseUrl to your desired URL

I am trying to handle popup using phantomjs as a driver
Please help on This .........
Thanks in Advance..!!!!
You have to take care of a lot of points here in your code :
While working with PhantomJS when you mention System.setProperty use the following code lines instead :
File src = new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path", src.getAbsolutePath());
DesiredCapabilities type of objects must be initiated with reference to DesiredCapabilities class only. So change to :
DesiredCapabilities caps = new DesiredCapabilities();
While using assertEquals use Assert.assertEquals as follows :
Assert.assertEquals(actualBoxMsg,"User or Password is not valid");
//
Assert.assertEquals(hometitle,"Guru99 Bank Manager HomePage");
As you are using TestNG, for Assert, use org.testng.Assert; instead of static org.testng.Assert.assertEquals; as an import :
import org.testng.Assert;
You need to wrap up the line d.quit() within a separate TestNG Annotated function too as follows :
#AfterMethod
public void tearDown() {
d.quit();
}
Here is your own code block which executes successfully :
package headlessBrowserTesting;
import java.io.File;
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.NoAlertPresentException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.Assert;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
public class PhantomJS_webdriver_binary
{
WebDriver d;
#BeforeMethod
public void launh_Browser() {
File src = new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path", src.getAbsolutePath());
DesiredCapabilities caps = new DesiredCapabilities();
((DesiredCapabilities) caps).setJavascriptEnabled(true);
((DesiredCapabilities) caps).setCapability("takesScreenshot", true);
d=new PhantomJSDriver(caps);
}
#Test
public void guru_banking_login_excel() throws Exception {
d.get("http://www.demo.guru99.com/V4/");
d.findElement(By.name("uid")).sendKeys("TestUser");
d.findElement(By.name("password")).sendKeys("testpwd");
d.findElement(By.name("btnLogin")).click();
try{
Alert alt = d.switchTo().alert();
String actualBoxMsg = alt.getText();
Assert.assertEquals(actualBoxMsg,"User or Password is not valid");
alt.accept();
}
catch (NoAlertPresentException Ex){
String hometitle=d.getTitle();
Assert.assertEquals(hometitle,"Guru99 Bank Manager HomePage");
}
}
#AfterMethod
public void tearDown() {
d.quit();
}
}
I have this class SignIn:
package automationFramework;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import pageObject.devSplashScreenPage;
import utility.BrowserType;
import utility.Constant;
import appModule.SignIn_Action;
public class SignIn {
public WebDriver driver;
#BeforeMethod
#Parameters("browser")
public void SetUp(String browser) {
BrowserType.Execute(driver, browser);
}
#Test
public void signIn() {
// Call Sign In function
SignIn_Action.Execute(driver, Constant.StudentUsername, Constant.StudentPassword);
}
#AfterMethod
public void Teardown() {
driver.quit();
}
}
Where I am calling this code below which chooses the specific browser by the parameter that is passed. It works perfectly fine, it picks up the right browser and executes.
package utility;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class BrowserType {
#Test
public static void Execute(WebDriver driver, String browser) {
// Set Browsers
if(browser.equalsIgnoreCase("firefox")) {
driver = new FirefoxDriver();
}
else if (browser.equalsIgnoreCase("chrome")) {
{System.setProperty("webdriver.chrome.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/chromedriver.exe");}
driver = new ChromeDriver();
}
else if (browser.equalsIgnoreCase("ie")) {
{System.setProperty("webdriver.ie.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/IEDriverServer.exe");}
driver = new InternetExplorerDriver();
{DesiredCapabilities iecapabilities = DesiredCapabilities.internetExplorer();
iecapabilities.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);}
}
// Implicit Wait and Maximize browser
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.manage().window().maximize();
// Navigate to URL
driver.get(Constant.URL);
}
}
So everything executes perfectly fine in #BeforeMethod, the issue I have is the test stops because the driver doesn't pass from #BeforeMethod to #Test.
How can I get the driver that is initiated by running BrowserType.class into the #Test Sign_in.class. I guess how can i return the driver properly from browsertype and call it in Sign_in #Test.
Thanks
You should make your Execute function return the driver:
public static WebDriver Execute(String browser) {
...
return driver;
}
In your test:
public void SetUp(String browser) {
driver = BrowserType.Execute(browser);
}
Solved like this:
BrowserType.java:
package utility;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class BrowserType {
#Test
public static WebDriver Execute(String browser) {
// Set Browsers
WebDriver driver = null;
if(browser.equalsIgnoreCase("firefox")) {
driver = new FirefoxDriver();
}
else if (browser.equalsIgnoreCase("chrome")) {
{System.setProperty("webdriver.chrome.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/chromedriver.exe");}
driver = new ChromeDriver();
}
else if (browser.equalsIgnoreCase("ie")) {
{System.setProperty("webdriver.ie.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/IEDriverServer.exe");}
driver = new InternetExplorerDriver();
{DesiredCapabilities iecapabilities = DesiredCapabilities.internetExplorer();
iecapabilities.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);}
}
// Implicit Wait and Maximize browser
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.manage().window().maximize();
// Navigate to URL
driver.get(Constant.URL);
return driver;
}
SignIn.java class:
package automationFramework;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import pageObject.devSplashScreenPage;
import utility.BrowserType;
import utility.Constant;
import appModule.SignIn_Action;
public class SignIn {
public WebDriver driver;
#BeforeMethod
#Parameters("browser")
public void SetUp(String browser) {
driver = BrowserType.Execute(browser);
}
#Test
public void signIn() {
// Call Sign In function
SignIn_Action.Execute(driver, Constant.StudentUsername, Constant.StudentPassword);
}
#AfterMethod
public void Teardown() {
driver.quit();
}
}
The way your doing things can be greatly improved.
public class BrowserTest extends TestBase{
#Test(dataProvider="test1")
public static void execute(WebDriverHelper helper, String browser) {
// Set Browsers
driver.get(url);
Just pass the driver object (coming from the DataProvider). I assume your generating the driver instance within the DataProvider method since your test method is already parameterized and takes the driver.
public class TestBase {
private WebDriver driver;
...
#BeforeMethod
#Parameters("browser")
public void setUp(Object[] params) {
driver = (WebDriverHelper)params.get(1);
browserName = (String)params.get(2);
this.setTestName( params.get(0) + "-" + browserName;
driver.navigateTo(startUrl);
}
This code I show above wont compile but what I am trying to convey here is that you need to use the optional TestNG arg to the #BeforeMethod method, which is Object[] , and it gives you access to objects passed to test methods, BEFORE the test method is called, such as getting access to a "driver helper" created in the DataProvider factory, and then doing some Capabilities setup on that before the test is ran.
#DataProvider(name = "test1")
public Object[][] createData1() {
return new Object[][] {
{ "Cedric", new WebDriverHelper(), "firefox" },
{ "Anne", new WebDriverHelper(), "chrome"}
};
}
public class TestSuiteDriver {
private static WebDriver driver;
#BeforeClass
public static void setUp(){
System.setProperty("webdriver.chrome.driver", "/Users/Kimberleyross/chromedriver");
driver = new ChromeDriver();
}
public static WebDriver getDriver() {
return TestSuiteDriver.driver;
}
}
