“If you need a framework to test web services, you may use a different set of tools within a framework,” says Jones. “You should be able to combine tools within a framework in a way that allows you to test, so you are not limited to just UI, integration, or web-services testing. Build your framework in a way that supports a range of testing goals.”
To do more with less, developers reused test scripts during development and integration stages to work more efficiently. The demand for new software built, and the constant change to software under development opened the door for automation testing practices to serve as a reliable control mechanism for testing the code (Automated Software Testing, 1999).
Selenium is possibly the most popular open-source test automation framework for Web applications. Being originated in the 2000s and evolved over a decade, Selenium has been an automation framework of choice for Web automation testers, especially for those who possess advanced programming and scripting skills. Selenium has become a core framework for other open-source test automation tools such as Katalon Studio, Watir, Protractor, and Robot Framework.
