Is there any term in software engineering like Real Load Replay or Real Data Replay? My manager said to me, to learn about this topic. But I have never seen this topic. Any help?
The idea behind Real Load Replay is having a set of test data reproducing conditions and combinations from real use of the application instead of creating it from scratch.
It is very useful when you need to test inputs, web petitions and any kind of data which does not include personal nor sensitive information.
Apart from database replay, you have tools to recreate real data on other environments.
For instance, Gor is a simple tool with a listener on a production environment which sends part of this real traffic to test environments, where it is replayed.
