Both manual and automated testing have their own advantages and limitations, and they cannot fully replace each other. Manual testing allows for comprehensive problem understanding and flexible exploration of different test angles, while automated testing saves time by executing numerous surface-level tests quickly. Despite the increasing adoption of automation, manual testing will always remain relevant due to the specific advantages mentioned above.
While automated testing offers efficiency and scalability, manual testing brings human judgement, adaptability, and expertise to certain aspects of testing, such as exploratory testing, UI/UX evaluation, handling complex scenarios, and adapting to changes. The combination of both manual and automated testing approaches ensures comprehensive test coverage and enhances the overall quality of the software.
