Selenium Components / Selenium’s Tool Suite
1) Selenium IDE (Integrated Development Environment)
2) Selenium RC (Remote Control)
3) Selenium WebDriver
4) Selenium Grid
1) Selenium IDE
It is a Firefox Browser Add on, used to create and execute Test Cases
Selenium IDE Features:
> Create Test Cases and Test Suites.
(We can Record Test Cases, or Type Test Steps using Element Locators and Selenese Commands/Selenium IDE Commands)
> Edit Test Cases
> Execute Test Cases and Test Suites
> Debug Test Cases.
> Enhance Test Cases
> Export Test Cases to other formats (Java, Ruby etc…)
Note: Selenium IDE Test case default format .html
———————————————————-
Drawbacks of Selenium IDE:
> It works only on Firefox Browser, doesn’t support other Browsers.
> It doesn’t support any Programming, so we can’t use Programming logic to enhance Test cases.
> It doesn’t support Data driven Testing.
> It is not suitable for Complex Test case design.
> No centralized maintenance of Elements/Objects.
2) Selenium RC (* Out dated)
3) Selenium WebDriver
> It is a Programming Interface to create and execute Test Cases.
———————————————
Selenium IDE has IDE only, but no programming Interface
Selenium WebDriver has programming interface only, but no IDE.
—————
UFT / QTP has both IDE as well as Programming Interface
————————–
> Selenium WebDriver supports various programming environments to write programs (Test scripts).
Java
C#
Python
Perl
Ruby
PHP
> Selenium WebDriver supports various Browsers
Mozilla Firefox
Google Chrome
IE
Safari
Opera etc…
> Selenium WebDriver supports various Operating Environments
MS Windows
Linux
Macintosh etc…
————————————————————–
Using Element Locators and WebDriver commands / methods we can create Test Cases
Element/ Object Locator/Property value
Button id next
Edit box name Email
————————————————————–
Dog height 30
color white
—————————————————–
Element Locator – To identify or recognize the Element
WebDriver Command/Method – To perform Operation on the Element
Element Operation
————————–
Edit box Entering a value
Button Click/Submit
Link Click
Check box Select/Unselect
Drop down box select an item
——————————————-
Drawbacks of Selenium WebDriver
> Selenium WebDriver has no IDE, so Creating Test cases is difficult and takes more time.
> No built-in Result Reporting facility.
> It doesn’t have an integreated spread sheet for Data related(Ex: Data driven testing) operations
———————————————————————————-
4 Selenium Grid
Selenium Grid for Parallel Test execution, No Test Design in Selenium Grid.
> Selenium Grid executes Test Cases across multiple browsers, operating environments and machines in parallel.
> Selenium Grid 2.0 supports Selenium RC Test Cases and Selenium WebDriver Test Cases.
——————————————————–
Focus on:
Test Automation using Selenium
i) Selenium WebDriver
(To create and execute Test Cases using Element Locators and WebDriver Commands/Methods)
ii) Java Programming
(To Enhance Test cases – Inserting verification points, Parameterization, Synchronization, error Handling, Adding Comments etc…)
iii) TestNG Testing Framework
(Grouping Test cases,
Executing Test batches,
Generate Test Reports,
Parallel Test execution, Data driven Testing etc…)
—————————————————————-
Parallel Test execution using Selenium Grid (Multiple Machines)
Parallel Test execution using Selenium WebDriver + TestNG (Single Machine)
