Cannot invoke By not finding elements on the webpage

Im writing a selenium project from scratch using the PageObject.
The below code is failing because the selenium webdriver is not finding elements on the webpage .
This is the error i get :
java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.SearchContext.findElement(org.openqa.selenium.By)" because "this.searchContext" is null
DriverBase.java :
In this class i setup the driver

final String password = prop.getProperty("PASSWORD");
System.out.println(username);
//wait.until(ExpectedConditions.visibilityOf(this.usernameTextBox));
usernameTextBox.clear();
passwordTextBox.clear();
usernameTextBox.sendKeys(username);
passwordTextBox.sendKeys(password);
submitButton.click();
//wait.until(ExpectedConditions.visibilityOf(this.tokenTextBox));
}
}
LoginPageTests.java :
In this class i write tests and i call methods from LoginPage.java Class
package com.EbankingA11y.testcases;
import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeTest;

public class LoginPageTest extends DriverBase {
public LoginPageTest() throws IOException {
super();
}
LoginPage loginPage = new LoginPage();
#BeforeTest
public void setup() throws InterruptedException {
initialization();
}
#Test
public void login() {
loginPage.performLogin();
}
}

I found that i have to declare the pages in the before methods after the initilisation ()
public class LoginPageTest extends DriverBase {
public LoginPageTest() throws IOException {
super();
}
// here
LoginPage loginPage;
TokenPage tokenPage;
#BeforeTest
public void setup() throws InterruptedException {
initialization();
//here
loginPage = new LoginPage();
tokenPage = new TokenPage();
}
#Test
public void login() {
tokenPage = loginPage.performLogin();
}
}
This is just worked for me

Code to avoid selenium stale element reference showing error in Eclipse editor

I am writing the following code to resolve stale element reference in selenium. However, in eclipse it is giving me error on: final boolean retrying (By by)-this line.Also, first i wanted to use public boolean retrying(By by) instead of final boolean retrying (By by), but that was giving me error from the eclipse editor.
package com.TSOne.tcone;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.StaleElementReferenceException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class CalenderFfdriver {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver",
"/Users/owner/desktop/chromedriver");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.get("http://www.path2usa.com/travel-companions");
driver.findElement(By.cssSelector("#travel_date")).click();
List<WebElement>dates =driver.findElements(By.cssSelector(".day"));
System.out.println(dates.size());
final boolean retrying (By by) {
boolean result = false;
int attempts = 0;
while(attempts < 2) {
try {
driver.findElement(By.xpath("//*[#class='datepicker-
switch']")).click();
result = true;
break;
} catch(StaleElementReferenceException e) {
}
attempts++;
}
return;
}
WebElement navigator =driver.findElement(By.cssSelector("
[class='datepicker-days'] th[class='next']"));
while(!driver.findElement(By.cssSelector("[class='datepicker-days']
th[class='datepicker-switch']")).getText().contains("April"))
driver.findElement(By.cssSelector("[class='datepicker-days']
th[class='next']")).click();
for(int i=0;i<dates.size();i++) {
String text=dates.get(i).getText();
if(text.equalsIgnoreCase("23"))
dates.get(i).click();
}
}
}

Define final boolean retrying (By by) method outside of your main method and it should work.
package ee.sims;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.StaleElementReferenceException;
import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;
public class CalederFfdriver {
private static WebDriver driver = new ChromeDriver();
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver",
"/Users/owner/desktop/chromedriver");
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.get("http://www.path2usa.com/travel-companions");
driver.findElement(By.cssSelector("#travel_date")).click();
List<WebElement>dates =driver.findElements(By.cssSelector(".day"));
System.out.println(dates.size());
WebElement navigator =driver.findElement(By.cssSelector("[class='datepicker-days'] th[class='next']"));
while(!driver.findElement(By.cssSelector("[class='datepicker-days'] th[class='datepicker-switch']")).getText().contains("April"))
driver.findElement(By.cssSelector("[class='datepicker-days'] th[class='next']")).click();
for(int i=0;i<dates.size();i++) {
String text=dates.get(i).getText();
if(text.equalsIgnoreCase("23"))
dates.get(i).click();
}
}
final boolean retrying (By by) {
boolean result = false;
int attempts = 0;
while(attempts < 2) {
try {
driver.findElement(By.xpath("//*[#class='datepicker-switch']")).click();
result = true;
break;
} catch(StaleElementReferenceException e) {
}
attempts++;
}
// note that i replaced "return;" here because it was a syntax error
return result;
}
}
The code above has no compilation errors.

The screenshot does not get saved in the directory in Selenium

So I am trying the code where i take a screenshot of a web page. I have used a class to generate random string value and then assign these values to the file name. However when I run the code, it executes completely but however the screenshots are never saved into the directory.
code:
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.apache.commons.io.FileUtils;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class ScreenShot {
private WebDriver driver;
private String BaseUrl;
#Before
public void setUp() throws Exception {
BaseUrl = "https://www.flock.co";
System.setProperty("webdriver.chrome.driver", "C:\\Automation\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
}
#Test
public void test() throws Exception {
driver.get(BaseUrl);
Thread.sleep(5000);
WebElement emailField = driver.findElement(By.xpath("//div[#id='main-area']//input"));
WebElement Button = driver.findElement(By.xpath("//div[#id='main-area']//button"));
emailField.sendKeys("incomeplete");
Button.click();
}
public static String getRandomString(int length) {
StringBuilder sb = new StringBuilder();
String characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
for (int i = 0; i < length; i++) {
int index = (int) (Math.random() * characters.length());
sb.append(characters.charAt(index));
}
return sb.toString();
}
#After
public void tearDown() throws Exception {
String fileName = getRandomString(10) + ".png";
String directory = "C:\\Users\\farzan.s.DIRECTI\\Desktop\\LetsKodeIt";
File sourceFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(sourceFile, new File(directory+fileName));
driver.quit();
}
}
However I remove this random string generator and directly specify the directory path in FileUtils, it works.
Code:
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.apache.commons.io.FileUtils;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class ScreenShot {
private WebDriver driver;
private String BaseUrl;
#Before
public void setUp() throws Exception {
BaseUrl = "https://www.flock.co";
System.setProperty("webdriver.chrome.driver", "C:\\Automation\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
}
#Test
public void test() throws Exception {
driver.get(BaseUrl);
Thread.sleep(5000);
WebElement emailField = driver.findElement(By.xpath("//div[#id='main-area']//input"));
WebElement Button = driver.findElement(By.xpath("//div[#id='main-area']//button"));
emailField.sendKeys("incomeplete");
Button.click();
}
#After
public void tearDown() throws Exception {
File sourceFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(sourceFile, new File(C:\\Users\\farzan.s.DIRECTI\\Desktop\\LetsKodeIt\jfjfnfh.png));
driver.quit();
}
}

You missed "\\" in path.
It should be
FileUtils.copyFile(sourceFile, new File(directory+"\\"+fileName));

Selenium Java - java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property

My FireFox Version 49.0.1
Selenium Version: Selenium-java-3.0.0-beta3
Java: 8.0.1010.13
I have replaced all the existing Selenium Jar Files with the new files. Added the gecko.Driver to my code still I am seeing this message:
Error Message:
java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property;
My Code:
import java.util.concurrent.TimeUnit;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class AbstractPage {
WebDriver Driver =new FirefoxDriver();
#Before
public void Homescreen() throws InterruptedException
{
System.getProperty("Webdriver.gecko.driver", "C:/geckodriver.exe");
System.setProperty("Webdriver.firefox.bin", "C:/Program Files (x86)/Mozilla Firefox/firefox.exe");
Driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Driver.get("URL");
Driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
#After
public void TestComplete() {
Driver.close();
}
#Test
public void Projects() {
Driver.findElement(By.id("login-form-username")).sendKeys("Login");
Driver.findElement(By.id("login-form-password")).sendKeys("Password");
Driver.findElement(By.id("quickSearchInput")).sendKeys("ID");
}
}

You can remove main() method from the code. unzip your gecko driver and save it to your local system with wires.exe.
my sample class path is
G:\ravik\Ravi-Training\Selenium\Marionette for firefox\wires.exe
public class AbstractPage
{
WebDriver Driver;
System.setProperty("WebDriver.gecko.Driver", "C:\\TEMP\\Temp1_geckodriver-v0.10.0-win64.zip");
Driver=new FirefoxDriver();
#Before
public void Homescreen() throws InterruptedException
{
Driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Driver.get("https://QualityAssurance.com");
Driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Driver.findElement(By.id("login-form-username")).sendKeys("Login");
Driver.findElement(By.id("login-form-password")).sendKeys("Password");
//JavascriptExecutor js = (JavascriptExecutor) Driver;
//js.executeScript("document.getElementById('login-form-password').setAttribute('value', val );");
}
#After
public void TestComplete() {
Driver.close();
}
#Test
public void Projects() {
Driver.findElement(By.id("quickSearchInput")).sendKeys("WMSSE-229");

Please replace below line
System.setProperty("WebDriver.gecko.Driver", C:\\TEMP\\Temp1_geckodriver-v0.10.0-win64.zip");
You should pass geckodriver.exe not Zip file.
String driverPath = "F:/Sample/Selenium3Example/Resources/";
System.setProperty("webdriver.firefox.marionette", driverPath+"geckodriver.exe");
You can make your code more cleaner when posting here.

You must do something like this:
System.setProperty("webdriver.gecko.driver", "C:/geckodriver.exe");
System.setProperty("webdriver.firefox.bin", "C:/Program Files (x86)/Mozilla Firefox/firefox.exe");
