Selenium Grid Code to Invoke Browsers

Posted by DurgaPrasad on 02:40
To generate and to execute selenium test scripts using grid,we need to know about below concepts:
  • DesiredCapabilites
  • RemoteWebDriver

DesiredCapabilites:
  • DesiredCapabilites is a class in org.openqa.selenium.remote.DesiredCapabilities package
  • DesiredCapabilities are options that you can use to customize and configure a browser session
  • It gives facility to set the properties of the browser. Such as to
    • set BrowserName
    • Platform
    • Version of Browser etc
  • We have to execute multiple TestCases on multiple Systems
    • Different browser with different version and different Operating System

RemoteWebDriver:
  • RemoteWebDriver is used to set which node (or machine) that our test will run against.
package com.selenium.grid;

import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;

import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class Grid {

static String browser = null;
static RemoteWebDriver driver = null;

public static void main(String[] args) throws MalformedURLException {

// Please Enter Your browser value in Console
System.out.println("Please Enter Your browser value in Console");
Scanner sc = new Scanner(System.in);
browser = sc.next();

// Please give your node IP address URL
// if your HUB and Node are
// same machine, if
// different in localhost
// give IP address
nodeURL = "http://localhost:5555/wd/hub";

if (browser.equalsIgnoreCase("firefox")) {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities = DesiredCapabilities.firefox();
capabilities.setBrowserName("firefox");
URL grid_url = new URL("http://localhost:5555/wd/hub");
driver = new RemoteWebDriver(grid_url, capabilities);
} else if (browser.equalsIgnoreCase("Chrome")) {
System.setProperty("webdriver.chrome.driver", "Give your chromedriver path");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities = DesiredCapabilities.chrome();
capabilities.setBrowserName("chrome");
URL grid_url = new URL("http://localhost:5555/wd/hub");
driver = new RemoteWebDriver(grid_url, capabilities);
}
// Accessing google
driver.get("http://www.google.com");
}
}
