Operational Readiness Test [ORT] is one of the software testing strategies. Operational Readiness Test (ORT) is performed at the final stage of testing when all other testing activities are performed and build ready for live deployment.
Operational Readiness Test (ORT)
Database Backup: Database backup is necessary when any disaster happens, or any data gets corrupted. Generally, every web application has one database which stores the data in the database. It could be any data like customer profile, the price of the product, images, articles, the number of products, log in and password information, etc. Database backup should be scheduled at every specified time, and this task should perform regularly. On the Operational Readiness Test perspective, you should test and validate that the database has been backed up successfully without loss of data. Testing can be performed with the help of developers or tools implemented to take the database backup at a specified time for the application developer.
Database Recovery: Database recovery testing should be performed whenever it might chance to lose data. Loss of data can happen at any point in time, and reason could be anything network failure, website down, Operating System, or any disaster. If any issues happen with the database, you should be able to recover the lost data and able to restore it. Recovery and restoration could be performed either manually or automatically depending on what mechanism applied to the application developer.
Software Installation and Configuration
Software Installation and Configuration test are performed to check the software developed are getting installed successfully on the system. Each step of installation instruction should be described, and there should not be any difficulty or issue to install the software. Also, Installation and configuration tests should perform to secure that the deployment package, scripts, and configurations work according to installation instructions. Deployed components to ORT shall be packaged and distributed to the available environment. Verification of installation, configuration, and of major functionality should be done by execution of (preferably automated) Smoke Tests.
Rollback: Rollback test should be performed once any new deployment is done and after deployment application is not working as expected. You should be in a condition to roll back the application to the last known working configuration in case problems occurs during the deployment. If any new deployment planned, make sure the previous working build is available if the situation comes to roll back the application to the previous working version.
Failover: Failover testing verifies that application proceeds as normal when a redundant component fails. To execute a failover test, you need to have defined failover scenarios. If a failure occurs in one component, you should have a reason or cause that causes failure? Failover test could be performed for network failover, component failover, server failover, etc. For example – If you place an order online, your order should be placed successfully even any backend component gets failed. A server could have many instances running by which request reaches the server, so if any instance gets failed, then, other instances should be capable of handling the request.
Supportability: In Supportability testing, we perform the following testing – Installation test, Rollback test, and Monitoring. The installation test and Rollback have been explained above. In monitoring, we check – Handling of events generated when the system is malfunctioning. We perform verification of monitoring mechanisms for the system. How are Availability, performance, and capacity being measured and reported?
Reliability: In the Reliability test, we perform Failover test and Recovery routines, which are explained above. Also, we check that Recovery Routines work within the conditions specified.
Performance: Generally, performance testing performed separately, but in the Operational Readiness Test, you should verify the application behavior under load. Start performing the load test with a specified number of users and check the application behavior manually. In other words, we can say perform sanity checks of the application under load.

Regression: In regression testing, you should perform testing of the other application functionalities, which are not part of the new implementation. You should check the functionality of other modules are working as expected, and the new change does not affect existing features. Generally, Regression Tests executed to secure and verify that integration to external systems works, and there is no effect on most critical business functionality.
Maintainability: Performing maintainability testing, we test installation routines and rollback for updates/patches for a database, infrastructure, and application. Maintaining the application should be easy.
Security: The following test approaches should be performed during security testing – Security Information and Event Management, Penetration Testing, Intrusion Detection and Prevention, Access control, source code review, data protection, etc.
