Working of Failover testing
- Consider the factors: Before performing failover testing like budget, time, team, technology, etc.
- Analysis on failover reasons and design solutions: Determine probable failure situations that the system might experience. Examine the causes of failover, including software bugs, hardware malfunctions, network problems, etc. It provides fixes for any flaws or vulnerabilities found in the failover procedure.
- Testing failover scenarios: It develops extensive test cases to replicate various failover scenarios. This covers both unplanned failovers (system or component failures) and scheduled failovers (maintenance). Test cases ought to address many facets of failover, such as load balancing, user impact, network rerouting, and data synchronization.
- Executing the test plan: To reduce the impact on production systems, carry out the failover test plan in a controlled setting. Keep an eye on how the system behaves during failover to make sure it satisfies the recovery point and recovery time objectives (RPO and RTO, respectively).
- Detailed report on failover: Keep a record of the failover testing findings, including any problems you ran across, how long it took to failover and how it affected customers or services. Assess problems according to their severity and offer suggestions for improvements.
- Necessary actions based on the report: Distribute the report on the failover test to all pertinent parties, such as project managers, developers, and system administrators. Determine what needs to be done and prioritize it based on the report’s conclusions. This might involve fixing found flaws in the system, updating failover setups or improving the documentation.
Failover Testing in Software Testing
Software products/services are tested multiple times before delivery to ensure that it is providing the required service. Testing before delivery doesn’t guarantee that no problem will occur in the future. Even sometimes the software application fails due to some unwanted event due to network issues or due to server-related problems. Failover testing aims to respond to these types of failures.
Suppose that the PC gets off due to some technical issue, and on restarting we open the browser, then a pop-up is shown saying Do you want to restore all pages? On clicking restore, all tabs are restored. The process of ensuring such restorations is known as FAILOVER TESTING.
