Automation testing improves software quality by executing test cases automatically using specialized tools and scripts. It reduces manual effort, increases testing efficiency, and helps teams deliver reliable software faster.
- Automates repetitive and time-consuming testing tasks.
- Improves accuracy and consistency of test results.
- Enables faster releases with better test coverage.
Example: An e-commerce company automates 1,000 regression test cases, reducing testing time from 3–4 days to 2–3 hours while improving release speed and reliability.
