Selenium RemoteWebDriver: Difference between WebDriver and RemoteWebDriver

RemoteWebDriver in Seleniumis an extension of the WebDriver interface that let tester run automated test cases on removed machines. It is wide used for executing tests across different browser, work systems, and environments use Selenium Grid.

Overview

1. What is Selenium RemoteWebDriver and Its Architecture?

  • RemoteWebDriver implements the WebDriver interface to execute handwriting on remote machines.
  • Works on aclient-server model:
    • Client libraries post tryout petition as JSON.
    • Server forward them to browser drivers like ChromeDriver or GeckoDriver.
  • Utile for running distributed tests across multiple environments.

2. Advantages of Using Selenium RemoteWebDriver for Testing

  • Enables parallel execution across multiple machine.
  • OS-agnostic: run tests on browsers unavailable locally.
  • Supports local examination of staging websites before go alive.
  • Returns elision with screenshots for fast debugging.

3. How to Install and Run RemoteWebDriver in Selenium Grid

  • Start Selenium server hub: java -jar selenium-server-standalone.jar -role hub
  • Register a node to the hub and access via Grid Console.
  • Write test scripts pointing RemoteWebDriver to the hub URL.
  • Add desired capabilities (browser, version, OS) to configure trial.

4. Comparing Selenium RemoteWebDriver vs WebDriver for Test Execution

  • RemoteWebDriver: For cross-browser, cross-OS testing on removed machines via Grid.
  • WebDriver: For direct, local browser automation.
  • RemoteWebDriver includes extra method for distributed environments, while WebDriver is simpler for local runs.

This article excuse what Selenium RemoteWebDriver is, its architecture, benefits, installation measure with examples, and how it equate with WebDriver for different testing needs.

What is a Selenium RemoteWebDriver?

The RemoteWebDriverclass implements the WebDriver interface to execute test scripts through the RemoteWebDriver host on a remote machine. This class is implemented under the package below:

java.lang.Object org.openqa.selenium.remote.RemoteWebDriver

Remote WebDriver Architecture

  • Remote WebDriver lie of a server and a client.
  • The waiter is a component that listens on a port for various requests from a Remote WebDriver client. Once the request is received, it forward the request to the browser driver:,, or.
  • The client libraries serve as a Remote WebDriver client. The client translates test playscript postulation to JSON payload and sends it across to the Remote WebDriver server using the JSON wire protocol. The diagram below depicts the Remote WebDriver architecture.
  • When test cases are executed, the WebDriver client libraries link with the browser driver directly. On the former hand, if one seek to execute tryout remotely, the WebDriver client library communicate with the Remote WebDriver server. Then, the server links to either of the browser drivers that the WebDriver client requests for.

Advantages of Selenium RemoteWebDriver

  • It allows for the execution of or batches on multiple machines at the like time
  • It enables test case execution with browsers that are not available on the current OS. In unproblematic terms, it is OS-independent.
  • It returns an elision with an accompanying screenshot so testers know what issue has occurred.
  • It permit examine of a web application on a remote server, even before create it live. Hence, saves time and cost with other bug catching.

Pro-Tip:With BrowserStack Local, you can test your staging website on 3000+ existent devices and browsers even before making it live, to ensure a seamless user experience.

When to use Selenium RemoteWebDriver?

Selenium Remote WebDriver can be used when you need to test your website in the local environs. It helps QAs test arrange websites before launch and enables them to debug any issues before customers experience them.

Selenium RemoteWebDriver Installation

The setup process here is simple. But, it require the user to be mindful of the Selenium Grid and its initiation. To understand the setup process in detail, refer to our.

Once the Selenium grid is installed, follow the steps below to configure the Selenium RemoteWebdriver.

  • Start the server on the command prompt using the command:
    java -jar selenium-server-standalone-3.3.1.jar -role hub

    The hub should now be running onlocalhost port 4444

  • Open another command prompt to add a node to the hub:
    java -jar selenium-server-standalone-3.3.1.jar -role node -hub http: //localhost:4444/grid/register
  • Open a web browser and navigate tohttp: //localhost:4444/grid/console. The grid console page will be visible. Connect to Selenium Hub to execute test cases.

Run Selenium RemoteWebDriver with help of an example

When the Selenium server and hub are connected and running, you can write a test case using RemoteWebDriver.

  • To run a remote WebDriver client, foremost, connect to RemoteWebDriver. Point the URL to the reference of the server running the tests. Also, set up the to customize the client. The example below instantiate a remote WebDriver aim level to the distant web server,www.myexamplebrowserstack.com.
FirefoxOptions firefoxOptions = new FirefoxOptions (); WebDriver driver = new RemoteWebDriver (new URL (`` http: //www.myexamplebrowserstack.com ''), firefoxOptions); driver.get (`` http: //www.google.com ''); driver.quit ();
  • Next, add the to customise the configuration. The RemoteWebDriver lead on JSON radio protocol. Hence it becomes necessary to add coveted capabilities and accomplish the and windows program.
ChromeOptions chromeOptions = new ChromeOptions (); chromeOptions.setCapability (`` browserVersion '', `` 74 ''); chromeOptions.setCapability (`` platformName '', `` Windows 10 ''); WebDriver driver = new RemoteWebDriver (new URL (`` http: //www.myexamplebrowserstack.com ''), chromeOptions); driver.get (`` http: //www.google.com ''); driver.quit ();
  • The adjacent step is to reassign the files from the client machine to the remote server. This can be achieved using the Local file sensor. The RemoteWebDriver transfers the files from the customer to the remote server. The dictation below helps to set the file demodulator.
driver.setFileDetector (new LocalFileDetector ());
  • Finally, the file can be uploaded to execute the test cases
driver.get (`` Path of the file ''); WebElement uploadfile = driver.findElement (By.id (`` myfile '')); uploadfile.sendKeys (`` File_path_value '');
