Automated user interaction in software testing refers to the process of simulating user actions and interactions with the software application using automated testing tools. This approach allows testers to automate the repetitive tasks that users would perform manually, such as clicking buttons, entering text, navigating through menus, and validating responses. By automating user interactions, testing teams can increase the efficiency of their testing processes, reduce the time required for testing cycles, and ensure consistent test results across different environments. Test automation tools like Selenium, Appium, and Ranorex are commonly used to automate user interactions and streamline the software testing process.
