Is There a Way to Reproduce Model Performance?

Data is really at the center of the model itself. How do you reproduce your tests where I build some sort of model right now? And I think the accuracy for that is say 60%. That depends on having some static data right now and that underlying data might change over time. So in the MLOps world, how do you plan for keeping tests that are reproducible that you can actually rely on over time as you change things?
