DevOps — Automated Testing in DevOps

Automated testing ensures that code changes do not break existing functionality. Types of automated tests include unit tests, integration tests, performance tests, and security tests. By integrating tests into CI/CD pipelines, teams can catch bugs early and release code confidently. Popular tools include Selenium, JUnit, and Postman for API testing. Automation saves time and reduces human error.

Example: Automatically running tests on every code commit to verify the app works correctly.
