In the software industry, a stage is reached when a product needs to be tested. Now, there are two ways in which this can be done- manual and automated. Since, manual testing is cost heavy and consumes a lot of time, companies prefer the automated alternative. Out of all the options available these days for automated testing, selenium simply stands out. And because it’s an open source framework, there are no licensing costs involved.

Selenium is a new generation automation testing tool to automate web based application/Mobile application. It is also the core technology in countless other browser automation tools, APIs and frameworks.
