Mobile applications are becoming increasingly complex and require more thorough testing to ensure they work seamlessly across different devices, browsers, and operating systems. Manual testing involves human users interacting with the application to identify usability issues, while automated testing uses pre-scripted tests to check for functionality and errors. Both approaches have their validity depending on the situation and can be used together in a blended approach known as integrated testing, which combines the strengths of both methods. This approach is recommended by companies such as Sauce Labs, which suggests that 80% of testing should be automated and 20% manual to save up to 70% of time and money spent testing. Manual testing provides valuable feedback on usability and appearance, while automated testing speeds up the testing process and reduces costs, making it essential for frequent releases.
