Tools of Selenium :
1.Selenium Integrated Development surroundings (IDE) :
Selenium IDE is enforced as a Firefox extension that provides record and playback practicality on check scripts. It permits testers to export recorded scripts in several languages like HTML, Java, Ruby, RSpec, Python, C++, JUnit, and TestNG. you'll be able to use this exported script in Se RC or Webdriver and Selenium IDE has restricted scope and also the generated check scripts don't seem to be strong and moveable.
2. Selenium remote :
Selenium RC (officially deprecated by selenium)allows checkers to jot down machine-controlled net application UI tests in any of the supported programming languages. It additionally involves an associate degree communications protocol proxy server that permits the browser to believe that the net application being tested comes from the domain provided by the proxy server.
3. Se WebDriver :
Selenium WebDriver (Selenium 2) is that the successor to Se RC and is far and away from the foremost necessary element of Se Suite. Selenium WebDriver provides a programming interface to make and execute check cases. check scripts are written to spot net components on sites so desired actions are performed on those components. Se WebDriver performs abundant quicker as compared to Se RC as a result of it makes direct calls to the net browsers. RC on the opposite hand wants an associate degree RC server to move with the net browser.
4. SeGrid :
Selenium Grid is additionally a vital element of Se Suite that permits the US to run our tests on total machines against different browsers in parallel. In straightforward words, we can run our tests at the same time on total machines running different browsers and operative systems.
Frameworks of Selenium :
- Keyword Driven check Framework :
Here, all the operations and directions area unit written in some external file stand out worksheet.
- Data-Driven check Framework :
During this framework, all the check information is generated from external files like CSV, XML or stand out.
- Hybrid check Framework :
This check framework takes advantage of each Keyword and data-driven framework. throughout this check, stand-out files area units are used as keywords that maintain check cases. Also, the supplier of the checking framework is employed for test data.
- Testing Framework :
organized by JUnit and NUnit, TestNG could be a testing framework. The new extended functionalities of TestNG have created it additional powerful and easier compared to different testing frameworks. It additionally supports ReportNG, which could be a straightforward hypertext markup language news plug-in and XLST plug-ins. This serves the aim of customizing or extending the default TestNG news vogue. Also, it provides the power to implement ‘IReporter’, associate degree interface which may be enforced to come up with bespoke TestNG reports. The ‘generate report()’ methodology functions despite everything the opposite suites have completed their execution and provide the report back to the required output directory.
