Pros and Cons of Using Selenium Web Driver

Pros

1. Allows for the WebDriver and Selenium APIs to live side-by-side
2. Provides a simple mechanism for a managed migration from the Selenium RC API to WebDriver’s
3. Does not require the standalone Selenium RC server to be run

Cons

1. Does not implement every method
2. More advanced Selenium usage (using “browserbot” or other built-in JavaScript methods from Selenium Core) may not work
3. Some methods may be slower due to underlying implementation differences.
