Selenium :Introduction

Selenium grew out of a testing framework that was developed to acceptance-test the functionality of ThoughtWorks web-based time & expense reporting application.It is open source software, released under the Apache 2.0 license, so it can be downloaded and used without charge.
A colleague recently shared this wonderful anecdote with me regarding how Open QA Selenium got its name in the software world.Mercury is a company that produces interactive testing solutions (Test Director for instance) - and they charge a lot of money for these tools. You can get involved in the Mercury Interactive Testing Solutions for this if you like.Selenium is open source- and as such costs you nothing.Selenium, as the chemists amongst you may be aware, is the antidote to Mercury poisoning.In the context of this open source tool, Open QA Selenium is the "antidote" to the commercial companies like Mercury Element
