Automated testing or test automation is a method in software testing that makes use of special software tools to control the execution of tests and then compares actual test results with predicted or expected results. All of this is done automatically with little or no intervention from the test engineer. Automation is used to to add additional testing that may be too difficult to perform manually.
Jones believes the most common reason for using test automation today is to shorten the regression test cycle. Regression tests are used to determine if changes to the software are the cause of new problems. They verify that a system under test hasn’t changed. To guard against introducing unintended changes, they become part of a regression test suite after the tests pass. Regression tests are automated to ensure regular feedback.
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.
Test automation tools can be expensive, and are usually employed in combination with manual testing. Test automation can be made cost-effective in the long term, especially when used repeatedly in regression testing. A good candidate for test automation is a test case for common flow of an application, as it is required to be executed (regression testing) every time an enhancement is made in the application. Test automation reduces the effort associated with manual testing. Manual effort is needed to develop and maintain automated checks, as well as reviewing test results.
One way to generate test cases automatically is model-based testing through use of a model of the system for test case generation, but research continues into a variety of alternative methodologies for doing so.[citation needed] In some cases, the model-based approach enables non-technical users to create automated business test cases in plain English so that no programming of any kind is needed in order to configure them for multiple operating systems, browsers, and smart devices.[2]
“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.”
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.
