Manual Testing Vs. Automation Testing

 

• Speed: Manual testing is slower since testers execute cases step-by-step, while automated testing runs scripts quickly and repeatedly.

• Accuracy: Human error is more likely in manual testing; automation ensures consistent and precise test execution.

• Cost Efficiency: Manual testing has lower upfront costs, but automation becomes cheaper over time for repetitive tests.

• Flexibility: Manual testing is ideal for exploratory, usability, and ad-hoc testing; automation is best for regression and performance tests.

• Maintenance: Manual tests require no script maintenance, whereas automated tests need regular updates when the app changes.

• Reusability: Automated scripts can be reused across builds and versions, unlike manual test cases.

• Human Insight: Manual testing allows testers to detect UI/UX issues or unexpected behaviors that automation might miss.

• Scalability: Automated testing supports large-scale projects and continuous integration, making it essential for agile development.
