Test automation Wikipedia. In software testing, test automation is the use of special software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that would be difficult to do manually. Test automation is critical for continuous delivery and continuous testing. OvervieweditSome software testing tasks, such as extensive low level interface regression testing, can be laborious and time consuming to do manually. In addition, a manual approach might not always be effective in finding certain classes of defects. Test automation offers a possibility to perform these types of testing effectively. Once automated tests have been developed, they can be run quickly and repeatedly. Many times, this can be a cost effective method for regression testing of software products that have a long maintenance life. Even minor patches over the lifetime of the application can cause existing features to break which were working at an earlier point in time. There are many approaches to test automation, however below are the general approaches used widely Graphical user interface testing. Selenium.jpg' alt='Automation Tool In Software Testing' title='Automation Tool In Software Testing' />A testing framework that generates user interface events such as keystrokes and mouse clicks, and observes the changes that result in the user interface, to validate that the observable behavior of the program is correct. API driven testing. Automation Tool In Software Testing' title='Automation Tool In Software 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. 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. In automated testing the test engineer or software quality assurance person must have software coding ability, since the test cases are written in the form of source code which, when run, produce output according to the assertions that are a part of it. Some test automation tools allow for test authoring to be done by keywords instead of coding, which do not require programming. 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. 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. What to automate, when to automate, or even whether one really needs automation are crucial decisions which the testing or development team must make. A multi vocal literature review of 5. System Under Test SUT, 2 the types and numbers of tests, 3 test tool, 4 human and organizational topics, and 5 cross cutting factors. The most frequent individual factors identified in the study were need for regression testing, economic factors, and maturity of SUT. Unit testingeditA growing trend in software development is the use of testing frameworks such as the x. Unit frameworks for example, JUnit and NUnit that allow the execution of unit tests to determine whether various sections of the code are acting as expected under various circumstances. Test cases describe tests that need to be run on the program to verify that the program runs as expected. Test automation mostly using unit testing is a key feature of agile software development, where it is known as test driven development TDD. Unit tests are written to define the functionality before the code is written. However, these unit tests evolve and are extended as coding progresses, issues are discovered and the code is subjected to refactoring. Only when all the tests for all the demanded features pass is the code considered complete. Proponents argue that it produces software that is both more reliable and less costly than code that is tested by manual exploration. It is considered more reliable because the code coverage is better, and because it is run constantly during development rather than once at the end of a waterfall development cycle. The developer discovers defects immediately upon making a change, when it is least expensive to fix. Finally, code refactoring is safer when unit testing is used transforming the code into a simpler form with less code duplication, but equivalent behavior, is much less likely to introduce new defects when the refactored code is covered by unit tests. Graphical User Interface GUI testingeditMany test automation tools provide record and playback features that allow users to interactively record user actions and replay them back any number of times, comparing actual results to those expected. The advantage of this approach is that it requires little or no software development. What is test Automation When test automation make sense What are the criteria to select best automation tool for your project Read this post to get answers to. Innovative software testing solutions tools and services for automated and manual testing of application software, Web sites, middleware, and system software. This approach can be applied to any application that has a graphical user interface. However, reliance on these features poses major reliability and maintainability problems. Relabelling a button or moving it to another part of the window may require the test to be re recorded. Record and playback also often adds irrelevant activities or incorrectly records some activities. A variation on this type of tool is for testing of web sites. Here, the interface is the web page. However, such a framework utilizes entirely different techniques because it is rendering HTML and listening to DOM Events instead of operating system events. Headless browsers or solutions based on Selenium Web Driver are normally used for this purpose. Another variation of this type of test automation tool is for testing mobile applications. This is very useful given the number of different sizes, resolutions, and operating systems used on mobile phones. For this variation, a framework is used in order to instantiate actions on the mobile device and to gather results of the actions. Another variation is script less test automation that does not use record and playback, but instead builds a modelclarification needed of the application and then enables the tester to create test cases by simply inserting test parameters and conditions, which requires no scripting skills. API driven testingeditAPI testing is also being widely used by software testers due to the difficulty of creating and maintaining GUI based automation testing. It involves directly testing APIs as part of integration testing, to determine if they meet expectations for functionality, reliability, performance, and security.
