What is selenium?

Selenium is one amongst the most wide used open source internet UI (User Interface) automation testing suite. It was originally developed by Jason Huggins in 2004 as an internal tool at Thought Works. Selenium is platforms and programming languages.
Selenium may be simply deployed on platforms like Windows, Linux, Solaris and Macintosh. Moreover, it supports OS (Operating System) for mobile applications like iOS, windows mobile and robot.
Selenium supports a variety of programming languages through the use of drivers specific to every language. Selenium web driver is most popular with Java and C#. Selenium test scripts may be coded in any of the supported programming languages and may be run directly in most up-to-date internet browsers. Browsers supported by selenium embrace net explorer, Mozilla Firefox, Google Chrome and expedition.
Selenium Basic language
Before continuing with this tutorial, allow us to 1st perceive a number of the Selenium Training in Marathahalli key ideas related to Automation testing of an application.
With the growing want for efficient software products, each software development cluster got to do a series of tests before launching the ultimate product into the market. Check engineers strive to catch the faults or bugs before the software product is free, yet delivered software always has defects. Even with the simplest manual testing processes, there is perpetually a prospect that the ultimate software product is left with a defect or is unable to fulfill the end user demand. Automation testing is that the best way to increase the effectiveness, efficiency and coverage of your software testing.
Automation Testing
Automation testing uses the specialized tools to automate the execution of manually designed test cases with none human intervention. Automation testing tools will access the test data, controls the execution of tests and compares the particular result against the expected result.
Automation testing covers each purposeful and performance test on an application.
• Automation is used for automation of test cases. As an example, regression tests, that are repetitive in nature, are automated.
• Performance automation is employed for automation of non-functional performance check cases. For instance, menstruation the response time of the appliance under considerable (say a hundred users) load.
Automation testing tools that are used for functional automation:
• Quick test professional, provided by hp.
• Rational golem, provided by IBM.
• Coded UI, provided by Microsoft.
• Selenium, open supply.
• Auto It, open supply.
Automation testing tools that are used for non-functional automation:
• Load Runner, provided by hp.
• JMeter, provided by Apache.
• Burp Suite, provided by PortSwigger.
• Acunetix, provided by Acunetix.
Why automated Testing
Automation testing has specific advantages for increase efficiency of any software. The Selenium Training In Marathahalli with placement key benefits of test automation are:
• A specific time without involving any human intervention. For instance, automated test can be automatically kicked off long, and the testers will analyze the results of the automated the next morning.
• Automated testing tools are able to playback pre-recorded and pre-defined actions.
• Automation testing supports frequent regression testing.
• It provides speedy feedback to developers.
• It provides unlimited iterations of test case execution.
• It provides disciplined documentation of test cases.
• Automated test generates customized defect reports.
Test Automation for internet Applications
If we take a look at the type of software applications prevailing in current market situation, most of the software applications are written as web-based applications to be run in an internet browser. In an era of extremely interactive and responsive software processes wherever many organizations are using some sort of agile methodology, check automation is often becoming a requirement for software comes.
The most effective manner to carry out check automation for internet application is to adopt a pyramid testing strategy. This pyramid testing strategy includes automation tests at 3 different levels. Unit testing represents the bottom and biggest share of this test automation pyramid. Next comes, service layer, or API testing. And finally, GUI tests sit at the highest.
