Example of Recovery Testing
- Example 1: When a system is receiving some data over a network for processing purposes, we can stimulate software failure by unplugging the system power. After a while, we can plug in the system again and test its ability to recover and continue receiving the data from where it stopped.
- Example 2: when a browser is working on multiple sessions, we can stimulate software failure by restarting the system. After restarting the system, we can check if it recovers from the failure and reloads all the sessions it was previously working on.
- Example 3: While downloading a movie over a Wifi network, if we move to a place where there is no network, then the downloading process will be interrupted. Now to check if the process recovers from the interruption and continues working as before, we move back to a place where there is a Wifi network. If the downloading resumes, then the software has a good recovery rate.
Types of Recovery Testing
- Database Recovery Testing: Evaluate the system’s capacity to recover from corrupted or malfunctioning databases. In order to test how well the system can restore the database to a consistent and useful condition, it involves intentionally destroying or damaging it.
- Load and Stress Recovery Testing: Determine how effectively the system bounces back from variables that affect performance, including heavy loads or stressful situations. It helps in determining if the system is capable of handling higher loads and in the event that it cannot, how soon it will resume normal operation after the load is dropped.
- Crash Recovery Testing: Determine how well the system bounces back from a hardware or software failure. To make sure the system can resume regular operations without losing data, it can involve unexpected shutdowns, abrupt power failures or a sudden halt of services.
- Security Recovery Testing: Examine the system’s resilience to security lapses, illegal access, and other security-related events by conducting security recovery testing. It guarantees that the system can recover from security breaches and helps discover loopholes in the security procedures, reducing the impact of any unauthorized access.
- Data Recovery Testing: Evaluate the system’s capacity to restore data following an unplanned disruption or failure. To make sure that data backups, restoration procedures and recovery mechanisms are efficient and dependable, this might involve planned data loss scenarios.
- Environment Recovery Testing: Examine the software’s ability to adjust to changes in dependencies or configurations in the environment. It guarantees that in the event of modifications to the underlying structure or environmental circumstances, the system can recover and go on operating as anticipated.
