Testing ?
Is the process of
evaluating a system or
its component(s) with
the intent to find
whether it satisfies
what it needs to do.


Automated Testing
 Testing a system or its
component(s) with an
use of an automation
tool is called
Automation testing.
 In a Robotic way


Why Automation Testing ?
 Automation does not require Human Intervention
 Automation increases speed of test execution

 Manual testing can be boring and hence error prone
 Automation saves you money


Automation Tool
 Is a Software or a package that
allows you to use high level
languages or keywords to create
scripts on top of a test framework
to manage the build and run of
scripts that communicate with
the Application under test
 To control execution of tests
 To compare actual outcomes to
expected outcomes
 To report the status (PASS/FAIL)


Selenium WebDriver
 Browser Automation
Framework
 It automates browser’s
 http://docs.seleniumhq.org/


Selenium WebDriver
 Selenium is an open Source tool and its free.
 Supports Cross Browser Testing. The Selenium tests
can be run on multiple browsers.
 Allows scripting in several languages like Java, C#,
Groovy, Ruby, PHP and Python.
 Assertion statements provide an efficient way of
comparing expected and actual results.
 Different browser implementations


Selenium Suite of Tools
 Selenium IDE
 Selenium Remote Control (aka) Selenium 1.0
(Deprecated)
 Selenium WebDriver (aka) Selenium 2.0(aka)
WebDriver
 Selenium GRID


Selenium IDE
 The Record and Playback tool


Why WebDriver ?
Because it’s a W3C Working Draft


WebDriver API
 How does the WebDriver API looks like ?
driver.findElement(By.name("q"))


UI Element Locators
 We Human’s know what exactly to do on the web
page, operations like click, double click…
 Automation is a robotic process and we need instruct
the bot to click ‘here’ by the element locators – the
objects.
 Different locators
id
css
xpath
linktext

Transformation from Manual to a
Automated Tester
Manual Interaction

Automated WebDriver API

Human Opens a browser and
loads the URL of app under test

WebDriver driver = new ChromeDriver();
driver.get(http://google.com);

Human Click on a button

driver.findElement(By.linkText(”Google")).click();

Human types in a name in text
field

driver.findElement(By.name("firstName")).clear();
driver.findElement(By.name("firstName")).sendKe
ys(”gdgChennai");

Human selects an option from a
dropdown

new
Select(driver.findElement(By.id("glsel"))).selectBy
VisibleText("GB");


CHROMEDRIVER

Chromium
Maintained and Developed by the Chromium Team
at Google

Browser Statistics


Interrogation
As a Web Developer, how can I automatically
verify the critical functionality of my app
works ?

As a Tester, how can I automatically verify the
critical functionality of app under test
performs what it supposed to do ?


ChromeDriver
Interoperable with WebDriver Clients
Open source and maintained by the members
of Chromium project


How does the test look like ?


How ChromeDriver works ?


ChromeDriver Implementation
Dev Tools
Provides access to internal of web app
•
•
•
•

Query and Manipulate DOM tree
Debugging JavaScript
Network Monitoring
Memory and Performance profiling

Extensions
Modify and enhance browser functionality
• Window control


Detailed Architecture View
ChromeDriver


Chrome Extensions
 Chrome Extensions can be either packed or
unpacked.
 Packed extensions are single file with a .crx extension
 Unpacked extensions are a directory containing the
extension, including a manifest.json file
