How do you test IT changes before and after deployment?

Testing IT changes before and after deployment is a critical process in software development. Here are some key steps involved:

• Before Deployment:
• Unit Testing: Developers test individual units or components of the software to check if they perform as expected.
• Integration Testing: Different units are combined and tested as a group to ensure they work together seamlessly.
• Regression Testing: Tests are re-run to confirm that new changes have not affected existing functionalities.
• After Deployment:
• Post-Release Testing: Continuous monitoring of the system’s performance to identify any issues that may arise after deployment.
• User Feedback: Gathering feedback from users to understand their experience with the new changes and make necessary improvements.

By following these testing processes before and after deployment, software development teams can effectively manage and maintain the quality of their products.
