Selenium Test Automation Success Reasons & Best Practices

Selenium Test Automation Success Reasons & Best Practices

Listen on the go!

It is a natural tendency globally that all development groups test their build before deploying and employ testers to identify all the bugs ahead of the release. Manual testing was proving to be the least effective owing to the manual errors and also due to the limitations in testing everything manually. As a solution to this situation, certain repeated tests were automated to increase the testing efficiency.

Automation testing has become critical as it improves accuracy, provides test coverage in short time, and at a low cost. The latest research statistics add more weight to the increasing need of automation testing. As per Transparency Market Research (TMR), the global test automation market, which in 2015 had a valuation of US $12.91 bn, is expected to reach US $85.84 bn by the end of 2024. As per TMR, the market for test automation in North America, which stood at US $5.70 bn in 2015, is expected to be worth US $29.78 bn by 2024. The region is thus likely to exhibit a CAGR of 20.3% during the forecast period. The region also held approximately 44% in the overall market in 2014. It is also expected to report lucrative prospects for security testing. The rapid deployment of mobile applications and Software as a Service (SaaS) on cloud will be dominant in driving market for test automation in North America.

There are multiple options available for testing automation to choose from based on the requirement, size of the project, turnaround time so on. Licensed automation tools such as QTP, WinRunner, Test complete, Ranorex, QA Wizard Pro, Silk Test, QA Test and Rational Robot are available to perform functional, regression and performance testing. Open source automation tools such as Selenium, SOAP UI, Robotium, WebDriver, Jmeter, Junit so on are also available to perform functional, regression and performance testing.

As per TMR report, sale from the functional testing segment is expected to be highest during the forecast period (2015 to 2024), followed by mobile testing and QA process design. The functional testing segment accounted for the dominant share of 23.2% in the market in 2015. It is expected to significantly gain from the continuously growing agile development practices and open source tools will have a dominant role to play. Normally companies/testers prefer open source tools to perform functional testing, and Selenium functional testing tool is considered the best open source tool available to test web applications at no cost.

The main reason for the success of Selenium is that the tests can be coded in any number of programming languages, they can be run directly in web browsers, and work across operating systems.

The second reason for the success of Selenium as the most powerful automation tool are its features that are simple to use – its capable user interfaces help meet 90% needs of web application testers. Document object model (DOM) level testing, great extensibility and flexibility, support for multiple browsers, accommodating object oriented programming languages like JAVA, .NET, Ruby, Perl, PHP, etc., provides the option of using wide range of IDEs based on the choice of development languages and more of these make it a preferred choice for many testers.
