Data Migration Testing: when an application moves to another technology or server, data migration testing can help validate that all the data from the old system is moved to the new system with zero loss and no downtime.
Adopting Big Data Testing Strategy
Based on my own experience and exposure to big data testing, adopting a big data testing strategy is about picking the right approach to implementation:
- It should start with initial actions on data ingested by the tester, that aims to verify extracted data for its accuracy. This might even involve the loading of test data across various locations.
- The next stage needs to take over validating the business logic on ingested data, usually done using tools like Hadoop or Hive.
- After successful validation, testers should take on the task of verifying output data to warehouse data.
- The fourth step is one of the most important parts of the testing strategy, where testers need to verify data migration testing, eliminating defects. This requires users to work through pre-migration testing, migration testing, and post-migration testing.
- The fifth stage of performance testing, testers need to work on data loading and throughput working on the rate of data created and consumed.
- Last but very important, the testers need to work on data processing speed, where sub-system performance is measured working across the workflow.
