What is the difference between app and website testing?

App Testing and Website Testing are both crucial aspects of software quality assurance, but they differ in their focus and methodologies due to the unique characteristics of mobile applications (apps) and websites. An App Tester specializes in mobile applications, focusing on mobile-specific elements, while a Website Tester's role is more broad, considering various web browsers and devices. Both types of testing are essential for delivering a seamless user experience and ensuring the quality and functionality of the respective applications or websites.
