Description: Web application testing is a critical process that ensures applications function correctly across different browsers and devices. This process involves evaluating the functionality, usability, performance, and security of the application. Through various techniques, such as manual and automated testing, the goal is to identify errors and ensure an optimal user experience. Automation in web application testing allows for efficient execution of repetitive tests, saving time and resources. Tools like Selenium, Cypress, and TestCafe are widely used to facilitate this process, enabling developers and testers to create scripts that simulate user interaction with the application. The importance of these tests lies in the growing reliance on web applications in everyday life and business, where any failure can result in significant losses. Therefore, automated testing not only improves software quality but also contributes to a faster and more reliable delivery of applications to the market.
