Difference between Selenium IDE, Selenium RC, Selenium WebDriver & Selenium Grid
1.
Selenium IDE (Integrated Development
Environment) :-
1. Firefox add-on Selenium IDE allows
users to record and re-play user actions in Firefox. It supports exporting the
recorded scripts into Selenium RC or Selenium WebDriver code.
2. Core part is based on
JavaScript and Supports different extensions in it.
3. It supports User
Interface so no need to use different programming language.
4. Supported only in
FireFox browser.
5. It is not object
oriented.
6. No need to start
server before executing the script.
7. Does not support
listeners.
8. Doesn’t support
mobile testing i.e. Android/IPhone applications.
2.
Selenium RC (Remote
Control) :-
1.
Selenium RC is the first version of Selenium API, which was
generally known as Selenium.
2. Core part is based on
JavaScript and Supports different extensions in it.
3. Doesn’t support User
Interface but accepts all programming languages – Java, Pearl, Ruby, Python,
C++, JavaScript, C#, Tecla etc.
4.
Supported
in all browsers including Mozilla FireFox, Google Chrome, Internet Explorer,
Safari Browser, Opera.
5.
It is
rarely object oriented.
6.
Needs to
start the server before executing test cases.
7.
Does not
support listeners.
8. Doesn’t support
mobile testing i.e. Android/IPhone applications.
3.
Selenium WebDriver
(Selenium 2) :-
1. Selenium WebDriver, provides APIs in a variety of languages
to allow for more control and the application of standard software development
practices.
2. It interacts natively with browser applications. Does not
affect if application has different coding language.
3. Doesn’t support User Interface, mainly uses Java programming
language, and supports all programming languages.
4. Supported in all types of browsers.
5. It
is fully object oriented.
6. Does
not need to start the server before executing test cases.
7. Supports
the implementation of listeners like TestNG listener.
8. It
supports all type of mobile testing. Android as well as IPhone applications.
4. Selenium Grid :-
1. Selenium Grid, makes
it possible to use the Selenium APIs to control browser instances distributed
over a grid of machines, allowing more tests to run in parallel.
2. JSON WIRE
PROTOCOL is
the underlying technology used by client side drivers to communicate with
server side RemoteWebDriver.
3.
Selenium
Grid is a tool uses Selenium Server to execute either Selenium RC or
Selenium WebDriver tests in parallel on different machines.
