Like the saying goes “You can’t control something you can”t measure”. Before you start collecting metrics, you need to step back and make sure your metrics are Specific, Measurable, Achievable, Relevant and Time-bound. This goes for pretty much anything you want to measure in life. Sometimes it’s better to step back from the issue, look at the big picture and create one or more feedback loops.

Regularly revisit and update test objectives, adapting them to the evolving needs of the data virtualization solution. This iterative approach ensures the ongoing effectiveness of the testing process.

The test cases should cover all the possible scenarios that can occur in the integrated environment. Moreover, the entire functions should be tested against the data sources in order to verify the results of the processes in data federation and virtualization.

The very hardest part of the process is to accurately define what the customer/client really needs and wants. Most often they don't know what they first need, and secondly want themselves, so you have to analyze their data sources and ask probing questions based on your analysis to help guide them in defining their objectives.
