The software development sector usually thinks of automated testing to save the bills of manual testing. In this post, professionals will talk about Selenium automation testing tool and its advantages. Since the cost of testing is a critical factor for any software development project, companies have started giving preference to open source test automation tools rather than investing in expensive commercial testing tools. Without licensing costs, open source automation testing tools offer competitive features. These features are leveraged by developers for automating the testing of software apps and web portals.
Developers can have an entire range of open source automation testing tools for all types of testing like functional, UAT, Web and performance.
Selenium is a free automated testing suite and not a single tool. Each tool of the Selenium caters distinct testing needs of a company. There are four components in Selenium –
1. Selenium IDE
Selenium IDE is the simplest framework in the suite of Selenium and is easiest one to learn. It acts as a Firefox plugin that programmers can easily install like another plug-in. Since it is the simplest framework, it is used as a prototyping tool. If programmers want to create more advanced test cases, they can either use Selenium RC or Web Driver.
2. Selenium RC
Selenium Remote Control (RC) was the first automated web testing tool that let users apply a programming language of their choice. It supports the following programming languages-
3. Selenium Grid
Selenium Grid is a tool used with Selenium RC altogether to run parallel tests throughout distinct machines and browsers at the same time.
4. Web Driver
It supports programming languages that are supported by Selenium RC.
Do you know the persons who contributed to the Selenium Project?
Who created major Selenium tools? Let us find out-
Selenium RC or Remote Control tool
Paul Hammant created a server that acts as an HTTP proxy to make the browser to believe that the web app and Selenium Core being tested come from the same domain. This system was known as Selenium Remote Control.
Selenium Grid was developed by Patrick Lightbody to locate the requirement of minimising test execution times. This system was initially named as Hosted QA by him and it was able to capture screenshots of the browser in critical phases, and simultaneously send out Selenium commands to distinct machines.
Selenium IDE tool
Selenium IDE was developed by Shinya Kasatani as a Firefox extension, which is used for automating the browser via a special feature of record-and-playback. He got the idea of Selenium IDE to enhance the speed in creating test cases.
WebDriver was the first cross-platform testing framework created by Simon Stewart to control the browser from the OS level.
Significance of Selenium
Selenium Automation Testing is the best option for modern days automated testing. It is gaining more significance and most of the testers and companies prefer it for automating the web-based app testing for both the GUI and the functionality.
Is there any way to select right Selenium tool as per your requirement?
Among four tools of Selenium, there are conditions that help you in making decision of selection of Selenium tool. We will discuss the conditions of every tool to help you in making better decision.
Selenium IDE – You can choose Selenium IDE if you want to-
• Learn about the Selenium and its concepts related to automated testing.
• Create tests with bit or zero knowledge in programming
• Create easy test suites and test cases
• Test web app just against Firefox
Selenium RC- You can choose the Selenium RC if you want to-
• Design a test with more expressive language
• Run your test against browsers on distinct OS
• Deploy the tests throughout several environments with Selenium Grid
• Test apps against a new browser supporting JS
• Test web apps with complex scenarios of Ajax
Selenium Grid- You can choose Selenium Grid if you want to-
• Run the scripts of your Selenium RC in distinct browsers and OS simultaneously
• Run a huge test suite to get it complete as soon as possible
WebDriver- You can choose WebDriver if you want to-
• Use specific programming language to design your test case
• Execute tests on HTMLUnit
• Test AJAX-based functionalities rich apps
• Customise test results
