Answer: Create a new instance of the browser you want to use using Selenium 2. Then pass this into the WebDriverBackedSelenium with the URL that you would like to test. It will look like this:

@Before
public void setUp(){
    driver = new FirefoxDriver();
    selenium =
      new WebDriverBackedSelenium(driver, http://book.theautomatedtester.co.uk)
}

Answer. We just need to instantiate it before our tests are expecting to use it, for example driver = new FirefoxDriver()

Answer: In Selenium 1 we had to pass in the locator to an element in the API call. In Selenium 2 we need to find the element on the page with Selenium 2 and then interact with it

Answer: Selenium 2 works very hard at trying to imitate what the user is likely to do. Selenium will find the hidden element but it will throw exceptions if you try to type or click on it

Answer: No

Answer: The code in the test needs to cast the driver to a JavascriptExecutor object and then call the execute method passing in the JavaScript snippet we would like it to execute

Answer: Yes

Answer: It returns a Plain Old Java Object (POJO) so that we can then cast it to the type that we need within our tests
