Automated testing is a software testing technique that uses automation technologies instead of human testers to execute tests, streamlining software testing by utilizing reusable test scripts and automation tools. Automation testing enhances test coverage, speeds up execution, and reduces the manual effort required for software testing, providing benefits such as simplified testing, faster testing speed, reduced risk of human error, cost savings, improved bug detection, comprehensive reporting capabilities, reliability, parallel testing, and information security. To get started with automated testing, one can install Python and Selenium WebDriver using pip, write a Python + Selenium automation test, and follow best practices to achieve better testing outcomes while reducing costs, enhancing efficiency, and accelerating the delivery of high-quality software products.
