Selenium WebDriver PROS & CONS

The initial release of Selenium had four main components. It is referred to as SeleniumRC

  • Selenium Integrated Development Environment(IDE)

WebDriver PROS / Advantage:

  • Selenium is open-source, so anyone can download and start using it.
  • It supports multiple languages for creating and executing tests using Java, C#, .Net, Python, Pearl, Ruby, PHP, and Javascript.
  • Its platform independence supports operating systems like Windows, Mac, Linux, and Unix.
  • It is used for cross-browser testing like Chrome, Firefox, IE, and Opera browsers.
  • It supports headless browsers (PhantomJS, HTMLUnitdriver, Chrome headless)
  • It can be integrated with an open-source unit testing framework (TestNG, JUnit – TDD, BDD Framework – Cucumber Jbehave Serenity)
  • It’s lightweight and uses fewer hardware resources than testing tools like UFT/QTP.
  • Available in the form of API.
  • Easily integrated with the CI-CD process (Jenkins)
  • It can be executed on the local machine as well as on cloud / Virtual machine/servers (Example – Browserstack, source labs, AWS, Docker)
  • We can customize the webdriver codebase because the source code is shared.
  • It Supports Parallel test execution using the selenium grid.
  • We can perform functional, regression, usability, and UAT Testing using selenium.
  • It supports testing Ajax functionalities and helps monitor changes in the content without the page load.

Selenium WebDriver CONS / Disadvantages

  • As it’s open-source, there is no direct support.
  • It is a set of tools, for example, JDK + Eclipse + Webdriver + TestNG + Firebug + Firepath, so tool setup is more complicated than other tools like QTP/UFT, where you configure one tool.
  • You need to learn to program. There is no scriptless/codeless automation.
  • Using selenium webdriver, we can not automate desktop application
  • There is no default reporting facility for test results.
  • CI-CD selenium provides no API for extra work like test case design, report, and build.
  • It is not supported to automate Scenarios like barcode/code captcha.

If you find I have missed mentioning some pros or cons, you can mention that in the comment section.

I love open-source technologies and am very passionate about software development. I like to share my knowledge with others, especially on technology that's why I have given all the examples as simple as possible to understand for beginners. All the code posted on my blog is developed, compiled, and tested in my development environment. If you find any mistakes or bugs, Please drop an email to, or You can join me on Linkedin.
