This is an interesting question. I've seen 1:1 copy of prod databases running in test environments. Very convenient from a dev perspective but a no-go for many customers. I've also seen test envs using fixtures only. More privacy-compliant, but it makes it harder for in-depth testing or to uncover weird edge cases.
