What is the purpose of automated testing?

Automated testing is necessary to improve the efficiency and reliability of the software verification process. It allows:

• Quickly and repeatedly executing tests without human intervention.
• Reducing regression testing time when code changes.
• Ensuring product quality stability through test repeatability.
• Early defect detection, which reduces the cost of fixing them.
• Integration with CI/CD processes for automatic quality control with each change.

For example, automated tests can be run after each commit to ensure that new changes haven't broken existing functionality.
