1. Efficiency: Automated tests can be run repeatedly at any time of day, without human intervention, making the process much faster compared to manual testing. 2. Cost-effectiveness: While the initial setup for automated tests can be expensive, the long-term savings are substantial as it reduces the need for extensive manual testing. 3. Accuracy: Automated tests eliminate the risk of human error, ensuring that the tests are executed in exactly the same manner each time. 4. Scalability: Automated testing can easily handle complex applications and large-scale projects, which might be challenging for manual testing methods.
