• have cross Browser compatibility (Firefox, Chrome, Internet Explorer, Safari etc.)
• have great platform compatibility (Windows, Mac OS, Linux etc.)
• supports multiple programming languages (Java, C#, Ruby, Python, Pearl etc.)
• has fresh and regular repository developments
• supports distributed testing

A framework is a constructive blend of various guidelines, coding standards, concepts, processes, practices, project hierarchies, modularity, reporting mechanism, test data injections etc. to pillar automation testing.

Selenium supports the following types of testing:
Functional Testing
Regression Testing

Selenium RC and WebDriver, together in a combination, are popularly known as Selenium 2. Selenium RC alone is also referred to as Selenium 1.

WebDriver is the latest selenium tool.

The following syntax can be used to launch Browser:
WebDriver driver = new FirefoxDriver();
WebDriver driver = new ChromeDriver();
WebDriver driver = new InternetExplorerDriver();

The values of the css properties can be retrieved using a get() method:
Syntax:
driver.findElement(By.id(“id“)).getCssValue(“name of css attribute”);
driver.findElement(By.id(“id“)).getCssValue(“font-size”);

Python does not use braces to indicate the start & stop of function. It uses indentation (Whitespaces) to make compiler understand start & stop of function.

The different drivers available in WebDriver are:

• FirefoxDriver
• InternetExplorerDriver
• ChromeDriver
• SafariDriver
• OperaDriver
• AndroidDriver
• IPhoneDriver
• HtmlUnitDriver

Some of the file types of the dataset can be: excel, xml, text, csv, etc.

Junit is a unit testing framework introduced by Apache. Junit is based on Java.
