Since Prefect code tends to be just annotated regular code, testing is easy and intuitive, as one can just run the code as if it was regular Python and only testing it on Prefect infrastructure when necessary. There is also a large amount of flexibility in how deployment occurs due to the modularization of all the moving parts (flows, infrastructure, deployments).
