Some 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.
We've emphasized the importance of getting everyone involved in automation. Here's how it works in my department. An integral part of each development team, the DevTester writes and executes manual test cases for the team's user stories. The tests are written using a methodology (see connect manual tests with automation using a clear methodology) that clarifies how to automate them later on. Once a feature is stable, the DevTester writes the actual automation tests. Then, there's the Developer. In addition to developing the application, the developer works with the DevTester to review both the test's design and the testing code itself. The developer's involvement in the automated tests increases his or her engagement in the automation efforts, which also means the DevTester can help with test maintenance should the need arise. The QA architect is an experienced QA professional who is instrumental in deciding which feature tests should be automated. This is the person with the higher-level view of the overall testing effort who can understand which test cases will yield the best ROI if automated. With a broader view of the application, the architect is also responsible for cross-feature and cross-team QA activities to make sure that end-to-end testing can also be automated.

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.
