Reducing the lines of code and make programmatic interface cleaner can be extra benefit of event listener.

While executing the automation scripts Selenium WebDriver track the numerous events that happen. By design, the…

To outshine in test automation profession trusting on education a single testing tool is not the recommended tactic. Irrespective of the tool you must acquire how to code. Pick up a programming language then learning the ins and outs of an automation tool can give the advantage. In this post compares two scripts that are for performing the same action using the same libraries. The screenshot captured below depicts the functionality. Robot Framework is the tool used for the example but similar features are available regardless of the tool.


Script 1 :
