Frequently Asked Questions

Selenium automation refers to the process of automating tests for web applications using Selenium. Selenium is the most preferred framework for automation testing on multiple browsers and platforms. The Selenium test-suite comprises four major components – Selenium IDE, Selenium RC, Selenium Grid, Selenium WebDriver.

Selenium WebDriver specifically helps QAs to automate tests for desired browsers. It also gives QAs the flexibility to use programing language of their choice for writing Selenium automation scripts.

Selenium WebDriver architecture consists of 4 main components: 

  • Selenium Client library
  • JSON wire protocol over HTTP
  • Browser Drivers
  • Browsers

Selenium WebDriver works in 3 simple steps:

  1. The JSON wire protocol converts every line of code into an HTTP request (URL)
  2. This HTTP request is passed to specific browser drivers
  3. To receive the HTTP requests, every browser driver uses an HTTP server. Once the browser driver receives the URL, it processes the request by passing it to a real browser over HTTP. Then, all commands in the Selenium script will be executed.

As organizations started adopting an agile approach towards software development, automating their tests became a critical step in ensuring faster release cycles. At the same time, open-source tools began to gain huge popularity for their efficiency and cost-effectiveness. Thus, Selenium being open-source and free to use automation framework became the primary choice when it came to automated cross-platform testing.

Whenever a developer develops a web-app, it needs to be tested thoroughly for usability and cross browser compatibility. For example, a QA needs to test the login page of an app on multiple browsers to ensure the login page works as expected across browsers. In this case, manually testing the login page on each browser is a pointlessly time-consuming process. This is where QAs use Selenium Automation Testing.

Selenium Automation Testing can also help QAs set up automated parallel tests on a Selenium Grid so web-apps can be tested simultaneously on multiple browsers, operating systems, and devices.

Every test case needs to be executed in a unique environment (real browsers, devices, operating systems). To do so, teams need access to real devices. Maintaining the devices and browser versions on-site is expensive and high effort.

On the other hand, using Selenium Automation Online is much simpler. By accessing a Selenium Grid online, one can eliminate infrastructure overheads and pre-configuration hassles.
