The automation testing tool has made the task quicker, errorless, and much more straightforward.

What is Selenium?

Selenium is a portable framework designed for automation testing of web applications that provides a playback tool for authoring functional tests without the compulsion of learning a test scripting language. The automated open-source testing tool comes in a set as a software suite comprising of the following elements, where each serves its purpose:

  • Selenium Integrated Development Environment (IDE)
  • Selenium Remote Control (RC)
  • WebDriver

  • You can only generate reports from Selenium using third-party tools like TestNG or JUnit
  • You cannot check Captcha or Barcode readers using Selenium
  • The user must hold prior programming language understanding
  • being a free tool, Selenium provides support and assistance via Selenium helping communities instead of having a vendor support care unit

Q8. What is the difference between assert & verify commands?
