Description: Multi-device testing is an automated testing approach that ensures an application functions correctly across a variety of devices, operating systems, and browsers. This type of testing is essential in a technological environment where users access applications from different platforms, such as smartphones, tablets, and desktop computers. Multi-device testing helps identify and correct errors that may arise due to differences in hardware, software, or network configurations. Additionally, it ensures that the user experience is consistent and satisfactory, regardless of the device used. Key features of these tests include the ability to simulate multiple environments, automation of test cases, and integration with test management tools. The relevance of multi-device testing lies in the growing diversity of devices in the market and the need for companies to deliver applications that work seamlessly across all of them, which in turn enhances customer satisfaction and reduces the risk of production failures.
