1.Browser Control: (Important Point)

Selenium RC and Selenium WebDriver

RC – which stands for Remote Control is the predecessor of Selenium Web Driver, Why it is called as Remote Control? Because it doesn’t interacts directly with the browse instead uses a HTTP Proxy to control the browser.  Selenium RC has a web server which is coded in Java, this server acts as the HTTP Proxy.

WebDriver- Without any need for remote control or the support of Selenium server it directly interacts with the browser. It uses the browser’s native support for automation.

2.Speed: (which matters the most)

RC – It is a bit slow while comparing with Selenium Web Driver because as described above RC uses a Javascript program to control the browser which is called as Selenium Core.

WebDriver – It is surely faster than RC because it approaches the browser directly without any intermediate requirement. It uses the browser’s own engine to control it.

3.API: (Here is the Point) – Application Program Interface

RC – It is bit complicated, Developers faces issue more often in selecting which key to use : type or typeKeys. And also different browsers uses different ways which also varies.

WebDriver – The commands here are very simple and also not redundant.

4.Browser Support: (Headless Support)

Headless: HTMLUnit browser is termed as Headless because it is invisible and GUI less

RC- It does not support Headless HTMLUnit browser. It needs a visible browser for its operation.

WebDriver- On other hand WebDriver supports HTMLUnit browser which is GUI less and also it is very fast browser and no need wait for page elements to load.
