How to Run same test on multiple browsers?

Question

I want to run same test in multiple browsers: What should be the required code in my configuration file?
Here is my code, what I have tried:

package util;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class DriverManager {
    public static WebDriver driver;
    String baseUrl="http://--";
    public DriverManager()
    {
        System.setProperty("webdriver.chrome.driver","/home/naveen/chromedriver");
        driver=new ChromeDriver();
        driver.get(baseUrl);
        driver.manage().window().maximize();
    }
}

Help me- What should I need to do changes in my above code for Running same test on multiple browsers Like-Chrome, Mozilla, IE...etc?

If I get your question correctly you want to run the same script in different browsers Then, write a method pass a browser name as a string, use a 'switch case' logic to determine which browser to initiate.

Demo code is as below:

public void open_Browser(String browserName) 
    {
        try 
        {
            System.out.printf("Opening %s browser.\n", browserName);

            switch (browserName)
            {
                case "firefox":
                {
                    System.setProperty("webdriver.gecko.driver","./Configuration File/geckodriver.exe");
                    driver = new FirefoxDriver();

                    break;
                }
                case "chrome":
                {
                    System.setProperty("webdriver.chrome.driver","./Configuration File/chromedriver.exe");
                    driver = new ChromeDriver();

                    break;
                }
                case "ie":
                {
                    System.setProperty("webdriver.ie.driver","./configuration_and_resources/IEdriverServer.exe");
                    driver = new InternetExplorerDriver(capabilities);

                    break;
                }

                default:
                    break;
            }
        } 
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    }

Use WebDriver.for, e.g.

require 'selenium-webdriver'
require 'rspec-expectations'

def setup(platform, browser_name, browser_version)
  caps = Selenium::WebDriver::Remote::Capabilities.send(browser_name.to_sym)
  caps.platform = platform
  caps.version = browser_version.to_s

  @driver = Selenium::WebDriver.for(
    desired_capabilities: caps)
  end

  def teardown
    @driver.quit
  end
end

If you mean in you question how to launch test on the multiple instances of different browsers, you should use cloud based tools, as SauceLabs, BrowserStack or Blazemeter, that help you to scale up your tests. To use cloud solution for launching you tests in multiple browsers is justified, as any browser requires considerable resources, as CPU and RAM. If launching tests in multiple browsers pursues the purpose to create a load, than you should to use webdriver sampler in Jmeter or Taurus + Selenium to scale up selenium tests and Blazemeter to launch them in the cloud.
