Q)What is Selenium?
Selenium is one of the most powerful open source automation tool for web application testing (even we can say acceptance testing for the web application) which lets you automate operations like — type, click, the selection from a drop down etc of a web page. Primarily developed in Java Script and browser technologies such as DHTML and Frames and hence supports all the major browsers on all the platforms.
Q) Who developed Selenium Tool and Why?
Jason Huggins and team developed this tool in 2004 when they were working for Thought work (IT outsourcing company). They created this tool for the testing of an internal time & expenses application written in (python).
Q) How is Selenium different from commercial browser automation tools?
Selenium is a library which is available in a gamut of languages i.e. java, C#, python, ruby, php etc while most commercial tools are limited in their capabilities of being able to use just one language. More over many of those tools have their own proprietary language which is of little use outside the domain of those tools. Most commercial tools focus on record and replay while Selenium emphasis on using Selenium IDE (Selenium record and replay) tool only to get acquainted with Selenium working and then move on to more mature Selenium libraries like Remote control (Selenium 1.0) and Web Driver (Selenium 2.o).
Though most commercial tools have built in capabilities of test reporting, error recovery mechanisms and Selenium does not provide any such features by default. But given the rich set of languages available with Selenium, it very easy to emulate such features.
Q) What are the set of tools available with Selenium?
Selenium has four set of tools — Selenium IDE, Selenium 1.0 (Selenium RC), Selenium 2.0 (WebDriver) and Selenium Grid. Selenium Core is another tool but since it is available as part of Selenium IDE as well as Selenium 1.o, it is not used in isolation.
