Mobile Testing is used to ensure the quality, performance, and security of mobile applications across various devices, operating systems, and network conditions. QA teams employ manual and automated testing methods to validate app functionality, UI/UX consistency, and compatibility with different screen sizes and hardware configurations. Advanced tools like Appium, Selenium, and cloud-based testing platforms enable efficient automation and real-time testing on multiple devices. Mobile testing also includes performance testing under varying network conditions, security testing to prevent vulnerabilities, and usability testing to enhance user experience. By leveraging comprehensive mobile testing strategies, it helps businesses deliver high-quality, reliable, and seamless mobile applications.
