2. @AfterClass: The annotated method with @AfterClass will be run after all the test methods in the current class have been run.
3. @BeforeMethod: The annotated method with @BeforeMethod will be run before each test method.
4. @AfterMethod: The annotated method with @AfterMethod will be run after each test method.
5. @Test: Marks a class or a method @Test with as part of the test.

6.What is the difference between Thread.Sleep() and Selenium.setSpeed()

9.What is Web Driver?

Web Driver uses a different underlying framework from Selenium’s javascript Selenium-Core. It also provides an alternative API with functionality not supported in Selenium-RC. WebDriver does not depend on a JavaScript core embedded within the browser; therefore it is able to avoid some long-running Selenium limitations.
WebDriver’s goal is to provide an API that establishes
A well-designed standard programming interface for web-app testing.
• Improved consistency between browsers.
