What is Recovery Testing?
Recovery Testing is a type of software testing that checks how well an application can recover from crashes, failures, or other unexpected issues. It involves intentionally causing problems in the software to see if it can quickly and effectively return to normal operation. This helps ensure the software is reliable and can handle unexpected situations without losing data or functionality.
Recovery tests for failures include
To ensure that a system is fault-tolerant and can recover well from failures, recovery testing is important to perform. A system is expected to recover from faults and resume its work within a pre-specified period. Recovery testing is essential for any mission-critical system, for example, defense systems, medical devices, etc. In such systems, there is a strict protocol that is imposed on how and within what period the system should recover from failure and how the system should behave during the failure.
A system or software should be recovery tested for failures like:
- Power supply failure
- The external server is unreachable
- Wireless network signal loss
- Physical conditions
- The external device not responding
- The external device is not responding as expected, etc.
Steps to be performed before executing a Recovery Test
A tester must ensure that the following steps are performed before carrying out the Recovery testing procedure :What is Recovery Testing?

Steps to be performed before executing a Recovery Test
A tester must ensure that the following steps are performed before carrying out the Recovery testing procedure :
- Recovery Analysis – It is important to analyze the system’s ability to allocate extra resources like servers or additional CPUs. This would help to better understand the recovery-related changes that can impact the working of the system. Also, each of the possible failures, their possible impact, their severity, and how to perform them should be studied.
- Test Plan preparation – Designing the test cases keeping in mind the environment and results obtained in recovery analysis.
- Test environment preparation – Designing the test environment according to the recovery analysis results.
- Maintaining Back-up – Information related to the software, like various states of the software and database should be backed up. Also, if the data is important, then the backing up of the data at multiple locations is important.
- Recovery personnel Allocation – For the recovery testing process, it is important to allocate recovery personnel who are aware and educated enough for the recovery testing being conducted.
- Documentation – This step emphasizes on documenting all the steps performed before and during the recovery testing so that the system can be analyzed for its performance in case of a failure.
