Facing a HttpHostConnectException while using geckodriver

Question

i just started setting up automation in my office with the help of selenium but strucked at the initial level only. I used a basic code initially just to check the browser is working and processing the code further but got an issue.

import java.io.IOException;
import java.net.InetAddress;
import java.util.concurrent.TimeUnit;

import org.apache.http.conn.HttpHostConnectException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

public class ABC {




public static void main(String[] args) 
{

    System.setProperty("webdriver.gecko.driver","C:\\Users\\12345678\\
    AppData\\Local\\Mozilla Firefox\\firefox.exe");

    DesiredCapabilities dc=DesiredCapabilities.firefox();
    FirefoxProfile profile = new FirefoxProfile();
    dc.setCapability(FirefoxDriver.PROFILE, profile);
    WebDriver driver =  new FirefoxDriver(dc);
    driver.get("http://www.google.com");
    driver.manage().timeouts().implicitlyWait(10L, TimeUnit.SECONDS);

}`


    **Below is the error i am facing**

Answer 1

Your code looks fine but a couple of points:

1. To work with Selenium 3.x & Mozila Firefox 52.x you need to download the latest gecko driver from this location and save it.

2. Instead of "firefox.exe" you need to provide absolute path of the "geckodriver.exe"

Replace:

System.setProperty("webdriver.gecko.driver","C:\\Users\\12345678\\
    AppData\\Local\\Mozilla Firefox\\firefox.exe");

By:

System.setProperty("webdriver.gecko.driver","C:\\your_directory\\geckodriver.exe");

3. Finally you code will look like:

   System.setProperty("webdriver.gecko.driver", "C:\\SeleniumUtilities\\BrowserDrivers\\geckodriver.exe");
   DesiredCapabilities dc = DesiredCapabilities.firefox();
   FirefoxProfile profile = new FirefoxProfile();
   dc.setCapability(FirefoxDriver.PROFILE, profile);
   WebDriver driver =  new FirefoxDriver(dc);
   driver.manage().window().maximize();
   driver.get("http:\\gmail.com");
   

This code executes good with me.

Let me know if this helps you.
