3. WHAT IS “SELENIUM”? - THE BASICS
• Selenium
• A suite of tools to automate web browsers across many platforms.
• Those tools are the Selenium IDE for Firefox and the Selenium WebDriver.
• Can be controlled by several programming languages and testing frameworks.
• Many GUI based browser automation tools, APIs, and frameworks are built on top of
Selenium.
4. SELENIUM IDE
• A Firefox add-on that does simple record
and playback of browser events.
• Ideal environment for quickly creating
Selenium tests.
• Offers Debugging and breakpoints for
tests created
• Export tests as HTML, Ruby scripts, and
other formats.
5. SELENIUM WEBDRIVER
• Selenium 1.0 + WebDriver = Selenium 2.xx
• A collection of language specific bindings to drive a browser.
• It makes direct calls to the browser using each browser’s native support for
automation.
• The key interface against which tests are to be written in Java.
6. BASIC TEST ENVIRONMENT CONFIGURATION
• Maven Project > TestNG (Assertions) > Selenium WebDriver > Browser
• Testing one local browser at a time on the same machine as the IDE/test runner that is
executing/running the test.
• Advantages of this configuration:
• Easy to troubleshoot your tests
• Watch as the tests run locally, observe potential defects as they occur
• Quick and easy to set up
7. DISADVANTAGES OF A BASIC CONFIGURATION
• Restricted to the browsers available to your OS version/local machine.
• In the case of IE, generally only the highest supported IE can be installed.
• Assuming you’re on Windows, you’re not able to test against other OS and browser
versions such as Safari or OSX and Linux versions of Chrome and Firefox.
• It’s not scalable
• Running a system or performance test can be taxing on your local machine and it holds
your resources hostage until the tests have completed.

10. SELENIUM GRID
• Supports distributed test execution.
• This means running tests in a “distributed test execution” environment.
• This allows you to scale test coverage by distributing your tests to several
machines, with the option of parallel execution.
• Manages multiple environments from a central point.
11. SELENIUM GRID CONT.
• A grid is made up of a HUB and several NODES.
• The HUB is the central point that will receive all test requests and distribute
them to the NODES.
• The NODES are where your testing will occur.
• One NODE can have several available browsers.
• A NODE can also be a mobile device.

13. WHY TESTNG?
• Superior Parameter based testing
• With @DataProvider
• Advanced dependency testing
• Tests can rely on each other
• Suite Testing
• Test groups and types
• TestNG can run JUnit tests
14. WHY MAVEN?
• Dependency Management
• Avoids common client conflicts
• Handles downloading, installing, and
keeping track of different version of
dependencies.
• Streamlined Build Process
• You don’t have to understand how a
project works to clone it and build it.
