Automated testing

Automated testing plays a vital role in software development. It ensures that certain software satisfies its intended requirements and operates correctly in various scenarios. Automated tests act as a protective barrier, preventing new changes from disrupting the existing functionality. They also help in early issue detection, reducing the cost and time required to address bugs that may otherwise be found after release. When changes are made to the application, automated tests can be rerun to confirm that no new errors have been introduced and that previously resolved issues have not re-surfaced.
