NullPointerException while running selenium

Question

Am getting null NullPointerException when running below code, i am just trying read excel path from properties file but getting error, please help me as I'd tried hard to resolve this problem

login script

public class Login1 {
    public static Properties props;
    public static WebDriver driver;
    public InputStream propertiesFilePath = this.getClass().getClassLoader()
    .getResourceAsStream("Config.properties");

    public static void main(String [] arg){
    }

    public  void Readproperties() throws IOException {
        props = new Properties();
        props.load(propertiesFilePath);
    }

    public static void  getDriver(){
        System.setProperty("webdriver.chrome.driver",               "C:\\Users\\aroy\\Desktop\\Sele\\chromedriver_win32\\chromedriver.exe");
        driver = new ChromeDriver();
    }
    public static void logintoapp(String acc, String passw){
        driver.findElement(By.xpath("//input[@id='userName']")).sendKeys(acc);
        driver.findElement(By.xpath("//input[@id='password']")).sendKeys(passw);
        driver.findElement(By.xpath("//button[@id='loginBtn']")).click();
        System.out.println("Login SuccessFully");
    }
}

Tesstcase:

package AtExecution;

import java.io.IOException;
import org.testng.annotations.Test;

import BeoreExecution.Login1;

public class Testcase extends Login1 {

    public static ExcelLib exel1;

    @Test
    public void login() throws IOException{
        Login1 x = new Login1();
        x.Readproperties();

        exel1 = new ExcelLib(Login1.props.getProperty("TestDataPath"));
        String siteurl = exel1.getCellData("Login_Credentials",    "TestUrl", 2);
        String acc = exel1.getCellData("Login_Credentials", "account", 2);
        String passw=exel1.getCellData("Login_Credentials", "Password", 2);
        Login1.getDriver();
        driver.get(siteurl);
        driver.manage().window().maximize();
        Login1.logintoapp(acc, passw);
    }
}

here is my log

Why initialize your WebDriver in your other class? Why not just initialize it in your test case class, then pass it as a parameter to a constructor in your other class? — Reez0, Nov 23 '17 at 18:51

You did't instantiate WebDriver instance in your test case class. You can follow the below way:

Return WebDriver from the method -

public static WebDriver  getDriver(){
    System.setProperty("webdriver.chrome.driver",               "C:\\Users\\aroy\\Desktop\\Sele\\chromedriver_win32\\chromedriver.exe");
    driver = new ChromeDriver();
    return driver;
}

Then call this method inside login test method like

WebDriver driver = Login1.getDriver();

Finally continue your next code.

@Abhijith how did you call the getDriver() method? Can you send me your implemented code in [chat](https://chat.stackoverflow.com/) box. – Ali Azam Nov 25 '17 at 07:14
Hi Ali, i cant able to create box – Abhijith Nov 25 '17 at 07:31
Login1 x = new Login1(); x.Readproperties(); exel1 = new ExcelLib(Login1.props.getProperty("TestDataPath")); String siteurl = exel1.getCellData("Login_Credentials", "TestUrl", 2); String acc = exel1.getCellData("Login_Credentials", "account", 2); String passw=exel1.getCellData("Login_Credentials", "Password", 2); Login1.getDriver(); driver.get(siteurl); driver.manage().window().maximize(); Login1.logintoapp(acc, passw); – Abhijith Nov 25 '17 at 07:34
@Abhijith Can you please send you getDriver method definition also? – Ali Azam Nov 25 '17 at 07:42
pls find getdrivermethod – Abhijith Nov 25 '17 at 07:46
public static WebDriver getDriver(){ System.setProperty("webdriver.chrome.driver", "C:\\Users\\aroy\\Desktop\\Sele\\chromedriver_win32\\chromedriver.exe"); driver = new ChromeDriver(); return driver; } – Abhijith Nov 25 '17 at 07:46
@Abhijith please come on [chat](https://chat.stackoverflow.com/) and upload both the class file. – Ali Azam Nov 25 '17 at 07:57
@Abhijith when you call the method, use the line `WebDriver driver = Login1.getDriver();` instead of `Login1.getDriver();` – Ali Azam Nov 25 '17 at 08:04
Hi Ali, i cant come to chat as it is saying i need 20 reputation but i have only 1 – Abhijith Nov 25 '17 at 08:18

The problem is in the below snippet of your code

public InputStream propertiesFilePath = this.getClass().getClassLoader()
    .getResourceAsStream("Config.properties");

    public  void Readproperties() throws IOException {
        props = new Properties();
        props.load(propertiesFilePath);
    }

Java is not finding a resource by the name Config.properties in your CLASSPATH. You would need to check and ensure that this file is available in the CLASSPATH and is readable by Java. Once this is fixed, your NullPointerException should go away.

i added my Config.properties in src/directories, any thing i am missing pls guide me — Abhijith, Nov 25 '17 at 06:59
