java.lang.NullPointerException error on Page Object Model with cucumber

I am getting java.lang.NullPointerException while following Page Object Model with Cucumber. I am not sure what I am doing wrong here, please help me on this
Below is my Test Base Class:
package com.qa.util;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.edge.EdgeDriver;

import org.openqa.selenium.ie.InternetExplorerDriver;
public class TestBase {
public static WebDriver driver;
public static Properties prop;
//public WebDriver initializeWebDriver() throws IOException
public static void initializeWebDriver() throws IOException
{
prop = new Properties();
FileInputStream fis = new FileInputStream("D:\\Automation\\WebAutomation\\src\\main\\java\\com\\qa\\config\\config.properties");
prop.load(fis);
String browserName = prop.getProperty("browser");
//Execute in Chrome
if(browserName.equals("Chrome"))
{
System.setProperty("webdriver.chrome.driver","D:\\Drivers\\chromedriver.exe");
driver=new ChromeDriver();
//driver.manage().window().maximize();
}
//Execute in FireFox
else if(browserName.equals("Firefox"))
{
System.setProperty("webdriver.gecko.driver","D:\\Drivers\\geckodriver-v0.19.1-win64(1)");
driver = new FirefoxDriver();
}
driver.manage().window().maximize();
driver.get(prop.getProperty("appURL"));
driver.manage().timeouts().pageLoadTimeout(TestUtil.PAGE_LOAD_TIMEOUT,TimeUnit.SECONDS);
driver.manage().timeouts().implicitlyWait(TestUtil.IMPLICIT_WAIT, TimeUnit.SECONDS);
return driver;
}
}
Below is my login page Objects Class
package com.qa.pages;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import com.qa.util.TestBase;
public class LoginPage extends TestBase {
public LoginPage() {
/*super(driver);
this.driver=driver;*/
PageFactory.initElements(driver, this);
}
// Login Page Title
public String validateLoginPageTitle() {
return driver.getTitle();
}
// Welcome text
#FindBy(css=".login-form > h2:nth-child(1)")
WebElement header;
public String loginPageHeaderText() {
return header.getText();
}
}
Below is my Step Def
package com.qa.stepdefinations;
import java.io.IOException;
import org.testng.Assert;
import com.qa.pages.LoginPage;
import com.qa.util.TestBase;
import cucumber.api.java.en.And;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;
public class LoginStepDef extends TestBase {
LoginPage LoginPage = new LoginPage();
#Given("^I launch browser and access the GE URL$")
public void i_launch_browser() throws IOException {
TestBase.initializeWebDriver();
}
#Then("^I am on Login Page$")
public void i_am_on_login_page() {
String expectedLoginPageTile = prop.getProperty("LoginPage_Title");
String actualLoginPageTitle = LoginPage.validateLoginPageTitle();
Assert.assertEquals(actualLoginPageTitle, expectedLoginPageTile);
}
#Then("^I verify header text is displaying$")
public void i_verify_header_text_is_displaying() {
String expectedHeaderText = prop.getProperty("LoginPage_Expected_Header");
String actualdHeaderText = LoginPage.loginPageHeaderText();
Assert.assertEquals(actualdHeaderText, expectedHeaderText);
}
}
The script is working fine for LoginPage.validateLoginPageTitle(); however, I am not sure why it is not working for the next step i.e. LoginPage.loginPageHeaderText();

It seems issue is with your locator, check if it is correct.
#FindBy(css="<b><em>.login-form > h2:nth-child(1)</em></b>")
WebElement header;

I have 100+ button in the page and I have to click on each button and to verify the link and page which opens after clicking

I have 100+ button in the page and I have to click on each button and to verify the link and page which opens after clicking.
so how to click without writing xpath for all 100+ button, i just need to click them and for each button different page will open.
Pls help me to proceed my selenium test

After you click the first button a new DOM is loaded, so click on the second (and third ...) will end with StaleElementReferenceException. You need to get all the href values first and then try them one by one. Just tried on web bbc.com with this code:
package navi;
import java.util.ArrayList;
import java.util.List;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.firefox.internal.ProfilesIni;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class Himanshu {
public static WebDriver driver;
#BeforeClass
public static void setUpClass() {
FirefoxOptions options = new FirefoxOptions();
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile selenium_profile = allProfiles.getProfile("selenium_profile");
options.setProfile(selenium_profile);
options.setBinary("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
System.setProperty("webdriver.gecko.driver", "C:\\Users\\pburgr\\Desktop\\geckodriver-v0.20.0-win64\\geckodriver.exe");
driver = new FirefoxDriver(options);
driver.manage().window().maximize();
}
#Before public void setUp() {} #After public void tearDown() {}
#AfterClass public static void tearDownClass() {driver.quit();}
#Test
public void lots_of_buttons() throws InterruptedException {
driver.get("http://www.bbc.com/");
// wait to page is fully loaded
wait_sec(driver, 5).until(ExpectedConditions.elementToBeClickable(By.xpath("//*[#id=\"orb-header\"]/div[1]/div[1]/a/img")));
// get all the desired webelements
List<WebElement> header_links = driver.findElements(By.xpath("//a[contains(#href,'x')]"));
// create new arraylist
ArrayList<String> hrefs = new ArrayList<String>();
// collect all the href values
for (WebElement link: header_links) {
hrefs.add(link.getAttribute("href"));
}
// visit all the URLs
for (String url: hrefs) {
driver.get(url);
Thread.sleep(1000);
// do some stuff here
}
}
// modified wait method
public WebDriverWait wait_sec(WebDriver driver, int sec) {
return new WebDriverWait(driver, sec);
}
}

Why does this ID-selection not work in Jsoup?

I am trying to get data from a webpage (http://steamcommunity.com/id/Winning117/games/?tab=all) using a specific tag but I keep getting null. My desired result is to get the "hours played" for a specific game - Cluckles' Adventure in this case.
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
public class TestScrape {
public static void main(String[] args) throws Exception {
String url = "http://steamcommunity.com/id/Winning117/games/?tab=all";
Document document = Jsoup.connect(url).get();
Element playTime = document.select("div#game_605250").first();
System.out.println(playTime);
}
}
Edit: How can I tell if a webpage is using JavaScript and is therefore unable to be parsed by Jsoup?

To execute javascript in java code there is Selenium :
Selenium-WebDriver makes direct calls to the browser using each
browser’s native support for automation.
To include it with maven use this dependency:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-server</artifactId>
<version>3.4.0</version>
</dependency>
Next I give you code of simple JUnit test that creates instance of WebDriver and goes to given url and executes simple script to get rgGames .
File chromedriver you have to download at https://sites.google.com/a/chromium.org/chromedriver/downloads.
package SeleniumProject.selenium;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Map;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriverService;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;
import junit.framework.TestCase;
#RunWith(JUnit4.class)
public class ChromeTest extends TestCase {
private static ChromeDriverService service;
private WebDriver driver;
#BeforeClass
public static void createAndStartService() {
service = new ChromeDriverService.Builder()
.usingDriverExecutable(new File("D:\\Downloads\\chromedriver_win32\\chromedriver.exe"))
.withVerbose(false).usingAnyFreePort().build();
try {
service.start();
} catch (IOException e) {
System.out.println("service didn't start");
// TODO Auto-generated catch block
e.printStackTrace();
}
}
#AfterClass
public static void createAndStopService() {
service.stop();
}
#Before
public void createDriver() {
ChromeOptions chromeOptions = new ChromeOptions();
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
driver = new RemoteWebDriver(service.getUrl(), capabilities);
}
#After
public void quitDriver() {
driver.quit();
}
#Test
public void testJS() {
JavascriptExecutor js = (JavascriptExecutor) driver;
// Load a new web page in the current browser window.
driver.get("http://steamcommunity.com/id/Winning117/games/?tab=all");
// Executes JavaScript in the context of the currently selected frame or
// window.
ArrayList<Map> list = (ArrayList<Map>) js.executeScript("return rgGames;");
// Map represent properties for one game
for (Map map : list) {
for (Object key : map.keySet()) {
// take each key to find key "name" and compare its vale to
// Cluckles' Adventure
if (key instanceof String && key.equals("name") && map.get(key).equals("Cluckles' Adventure")) {
// print all properties for game Cluckles' Adventure
map.forEach((key1, value) -> {
System.out.println(key1 + " : " + value);
});
}
}
}
}
}
As you can see selenium loads page at
driver.get("http://steamcommunity.com/id/Winning117/games/?tab=all");
And to get data of all games by Winning117 it returns rgGames variable:
ArrayList<Map> list = (ArrayList<Map>) js.executeScript("return rgGames;");

The page you want to scrape is load by js,and there is not any #game_605250 element that jsoup get.All datas are write in page by using js.
But when I print document to a file ,I see some data like this:
<script language="javascript">
var rgGames = [{"appid":224260,"name":"No More Room in Hell","logo":"http:\/\/cdn.steamstatic.com.8686c.com\/steamcommunity\/public\/images\/apps\/224260\/670e9aba35dc53a6eb2bc686d302d357a4939489.jpg","friendlyURL":224260,"availStatLinks":{"achievements":true,"global_achievements":true,"stats":false,"leaderboards":false,"global_leaderboards":false},"hours_forever":"515","last_played":1492042097},{"appid":241540,"name":"State of Decay","logo":"http:\/\/....
then,you can extract 'rgGames' by some StringTools and format it to json obj.
It't not a clerver method,but it worked

try this :
public class TestScrape {
public static void main(String[] args) throws Exception {
String url = "http://steamcommunity.com/id/Winning117/games/?tab=all";
Document document = Jsoup.connect(url).get();
Element playTime = document.select("div#game_605250");
Elements val = playTime.select(".hours_played");
System.out.println(val.text());
}
}

Data driven testing in Selenium using POI and TestNG ..code getting error

Using Selenium, I have written the below code to read data from an Excel sheet and key in an email and password into Facebook's login page. Error is Unhandled expression to use try/catch. How can I resolve this?
package Excelpack;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Test;
import org.testng.annotations.DataProvider;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
public class ClassTwo {
WebDriver driver;
String username;
String password;
#Test(dataProvider="testdata")
public void testFireFox(String uname, String password1){
driver.findElement(By.id("email")).clear();
driver.findElement(By.id("email")).sendKeys(uname);
driver.findElement(By.id("pass")).clear();
driver.findElement(By.id("pass")).sendKeys(password1);
}
#DataProvider(name="testdata")
public Object[][] TestDataFeed1()
{
FileInputStream fis=new FileInputStream("D:\\book3.xlsx");
XSSFWorkbook wb=new XSSFWorkbook(fis);
XSSFSheet sh1= wb.getSheetAt(0);
int numrow = sh1.getLastRowNum()-sh1.getFirstRowNum();
int colnum =sh1.getRow(1).getLastCellNum()+1;
Object [][] facebookdata=new Object[numrow][colnum];
for(int i=0;i<numrow;i++)
{
facebookdata[i][0]=sh1.getRow(0).getCell(i).getStringCellValue();
facebookdata[i][1]=sh1.getRow(1).getCell(i).getStringCellValue();
}
return facebookdata;
}
#BeforeTest
public void Setup(){
driver=new FirefoxDriver();
driver.manage().window().maximize();
driver.get("https://www.facebook.com/");
}
}

If you are using any IDE like eclipse or intellijI then IDE would prompt you with the solution as to add "throws necessary exception" or write the block of code in try/catch. from the looks of the code it seems you would need to declare throws exception on your dataprovider TestDataFeed1.

Automated testing using selenium with firefox browser

I downloaded the code below and used it for some tests and u=it ran yesterday but since today the code stopped working. My tests are failing now which was not happening before. It throws up an error saying org.openqa.selenium.ElementNotVisibleException: element is not currently visible so cannot interact with element.
package org.openqa.selenium.example;
//import org.openqa.selenium.browserlaunchers.locators.GoogleChromeLocator;
//import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
//import org.openqa.selenium.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
//import org.openqa.selenium.chrome.*;
import org.openqa.selenium.firefox.*;
import org.openqa.selenium.firefox.FirefoxDriver;
//import org.openqa.selenium.support.ui.Select;
//import org.openqa.selenium.net.UrlChecker;
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class KongaUrlTest
{
private WebDriver driver;
private String baseUrl;
//private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();
#Before
public void setUp() throws Exception
{
driver = new FirefoxDriver();
baseUrl = "http://www.konga.com/";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
#Test
public void testFirefoxWebdriver() throws Exception
{
driver.get(baseUrl);
driver.findElement(By.cssSelector("a.vertnavlink > span")).click();
try
{
assertEquals("Phones & Tablets | Konga Nigeria", driver.getTitle());
System.out.println(driver.getTitle());
}
catch (Error e)
{
verificationErrors.append(e.toString());
}
}
#After
public void tearDown() throws Exception
{
System.out.println(driver.getCurrentUrl());
driver.quit();
}
}

There's a blocking dialog being displayed. It's probably displayed each time Selenium opens a new browser and navigates to that site. Close that dialog first:
driver.get(baseUrl);
try
{
driver.findElement(By.cssSelector(".fancybox-close")).click();
}
catch { }
driver.findElement(By.cssSelector("a.vertnavlink > span")).click();
