The components of Selenium Suite are as follows:

• IDE Selenium: It is a Firefox/Chrome add-on designed to make writing automation scripts go FASTER. It captures user activities in the web browser and saves them as a script that may be reused.
• Remote Control for Selenium (RC): RC is a server that lets users write application tests in a number of different programming languages. This server accepts the commands from the test script and sends them to the browser as Selenium core JAVASCRIPT commands. The browser then responds appropriately.
• WebDriver for Selenium: WebDriver is a programming interface that AIDS in the development and execution of test CASES. It includes the ability to operate on web items. WebDriver, unlike RC, does not require a separate server and interacts directly with browser apps.
• Grid of Selenium: The grid was created to deliver commands to multiple machines at the same time. It enables the running of tests in parallel across multiple browsers and OPERATING systems.
