Those who believe they will be actively customizing their automated test environments may want to start with Selenium and customize it from there, whereas those who want to begin in a more structured test environment may be better off with one of the systems that are built on top of Selenium. Selenium can be scripted in a multitude of languages, including Java, Python, PHP, C#, and Perl.
“Selenium is the go-to UI automation tool. The other credible open source tools are essentially a wrap-around tool around Selenium. For web service testing, I prefer REST Assured. SoapUI is another option used frequently and offers a professional version in addition to open source. Testing G and Junit are popular for verification tools. For BDD, Cucumber and Specflow are popular with the Microsoft stack of development tools.”
API driven testing. A testing framework that uses a programming interface to the application to validate the behaviour under test. Typically API driven testing bypasses application user interface altogether. It can also be testing public (usually) interfaces to classes, modules or libraries are tested with a variety of input arguments to validate that the results that are returned are correct.
Some business applications are interactive, i.e., they have a graphical user interface or user interface and users can query/modify/input data and view results instantaneously. They can also run reports instantaneously. Some business applications run in batch mode: they are set up to run based on a predetermined event/time and a business user does not need to initiate them or monitor them.
Katalon Studio is a unique tool that is designed to be run both by automation testers and programmers and developers. There are different levels of testing skill set available, and the testing processes include the ability to automate tests across mobile applications, web services, and web applications. Katalon Studio is built on top of Appium and Selenium, and consequently offers much of the functionality of these solutions.
Robust GUI test automation begins with the reliable object identification provided by Ranorex Spy. This tool can be used alone or from within the Ranorex Studio environment to deliver industry-leading recognition of GUI objects and controls, and ensure that each user interface element is uniquely identified using the powerful RanoreXPath syntax. Information on identified objects can be shared with team members through snapshot files, or stored in the Ranorex object repository for use in automated tests. The object repository in Ranorex Studio manages identified UI objects, so that they are editable and re-usable across testing projects. Features of the repository include the ability to assign meaningful names to repository objects to make them more maintainable, set default values, or link objects to parameter values. Ranorex Studio tools support best practices in automated test case design, including separation of test data from procedures, use of local and global parameters to pass values, and easily reusable code modules that can be shared by the entire team.
