Java

C#

Python

Perl

Ruby

PHP
-------------------------------------------------------
2) History of the Selenium Project

> Selenium get-go came to life inwards 2004.

> In 2006, Selenium WebDriver was launched at Google.

> In 2008, the whole Selenium squad decided to merge Selenium WebDriver amongst selenium RC
in gild to cast to a greater extent than powerful tool called Selenium 2.0

Selenium 1.0
(Selenium IDE + Selenium RC + Selenium Grid)

Selenium 2.0
(Selenium IDE + Selenium RC + Selenium WebDriver + Selenium Grid)

Selenium 3.0 Coming
-------------------------------------------------------
3) Selenium’s Tool suite / Selenium Components 

i) Selenium IDE
ii) Selenium RC (*Out Dated)
iii) Selenium WebDriver
iv) Selenium Grid

i) Selenium IDE (Integrated Development Environment)

It is a Firefox Browser Add on, used to practice together with execute Test cases.

Selenium IDE features:

> Create Test Cases, Test Suites
(Record or Type Test Steps)

> Edit Cases

> Execute Test Cases, Test suites

> Debug Test Cases

> Enhance Test Cases

> Export Test Cases to other formats (java, ruby etc...)

Note: Selenium IDE Test Case default format is .html
--------------------------------------------------------------
Drawbacks of Selenium IDE

> It industrial plant on Mozilla Firefox Browser only.

> It doesn't back upwardly programming logic/features to elevate Test Cases

> It doesn't back upwardly Data Driven Testing

> It is non suitable for complex Test illustration design

> No centralized maintenance of Elements / objects
------------------------------------
ii) Selenium RC (* Out Dated)
-----------------------------------
iii) Selenium WebDriver

> Selenium WebDriver is a Programming Interface (No IDE) to practice together with execute Test Cases.

Selenium WebDriver - Programming Interface, no IDE
Selenium IDE - IDE but no Programming interface
UFT/QTP - IDE every bit good every bit Programming Interface
-----------------------------------------------------------

Macintose Etc...
--------------------------------------------------------------
Drawbacks of Selenium WebDriver

> No built-in Result Reporting facility

> Selenium WebDriver has no IDE, takes to a greater extent than fourth dimension to practice Test Cases.

> It doesn't direct maintain an integrated spread canvas for Data driven testing
-----------------------------------
iv) Selenium Grid

> Selenium Grid Executes Test cases across multiple browsers, operating environments
and machines inwards Parallel

> Selenium Grid 2.0 supports Selenium RC Test Cases together with Selenium WebDriver Test Cases.
-----------------------------------
You Focus on:

Test Automation using Selenium

i) Selenium WebDriver
(To practice together with execute Test Cases using Element Locators together with WebDriver API Commands)

ii) Java programming
(To elevate Test cases)

iii) TestNG Testing Framework
(To grouping Test cases, execute Test batches together with generate Test Reports.
-------------------------------------------------------
4) Platforms Supported yesteryear Selenium

a) Browsers
--------------
Google Chrome
Mozilla Firefox
IE
Opera
Safari etc...

b) Operating Systems
------------------------
MS Windows
Linux
Macintosh etc...

c) Programming Languages
------------------------------
Java
C#

Computer Software

CUI based Application
1) Desktop Applications - No
2) Web Applications - Yes
Hybrid Application

Mobile Software
1) Native Application - No
2) Web Apps - Yes
3) Hybrid Applications -No
-------------------------------------------------------
5) Selenium License

All Selenium Projects released nether the Apache 2.0 License

> Anybody tin download together with purpose all Selenium Projects / Components amongst gratis of cost
> Anybody tin alter the rootage code together with distribute the rootage code.

** Selling modified code is non allowed.
--------------------------------------------------------------
6) Testing Frameworks together with other Tools used inwards Selenium

Testing Frameworks

Java Platform
i) JUnit
ii) TestNG - To grouping Test cases, Execute Test Batches, together with Generate Reports

.NET
NUnit
----------------------------------------
Eclipse IDE - To write together with execute Java Programs

Firebug together with Firpath plug ins for Mozilla Firefox browser to inspect elements
(Page Inspector built-in characteristic also at that spot inwards Firefox browser)

For Google Chrome, IE browsers, built-in developer tools available
-------------------------------
Identifying Elements together with performing operations on Elements
-----------------------------------------------------------
Browser Drivers
Mozilla Firefox is default browser

For Chrome, IE etc... browsers, involve to download browser drivers together with ready path.
-------------------------------------------------------
7) Advantages of Selenium

i) Selenium is an Open Source Software Tools Suite

ii) Selenium supports diverse Browsers (Firefox, Chrome, IE, Safari, Opera etc...)

iii) Selenium supports diverse Programming languages (Java/Python/C#/Perl/Ruby/PHP)

iv) Selenium supports diverse operating environments (MS Windows, Linux, Mac etc...)

v) Selenium supports Parallel Testing

vi) Selenium uses less Hardware resources.
-------------------------------------------------------
8) Disadvantages of Selenium

i) Selenium supports Web Applications / Browser based Applications only.

ii) No reliable Technical back upwardly from anybody.

iii) Difficult to use, takes to a greater extent than fourth dimension to practice Test cases.
----------------
Create Tests

UFT

Record / Descriptive programming to practice basic steps
Use Checkpoints / VBScript Flow control; statements to insert verification points
Use Data Table / Use VBScript Flow command together with Excel Object for Data driven Testing
Write Comments

Selenium

Selenium IDE
Record / Type steps to practice basic steps
Use Selenese Commands (Assert/Verify commands)
No support
Write Comments

Selenium WebDriver
Write Test Steps using Element Locators together with WebDriver Commands / Methods
Use Programming logic / Flow Control or Testing Framework Assert methods
Use Programming features (Text file, Excel etc...) 
Write Comments
---------------------
iv) Difficult setup Test Environment
