Having no other users means it doesn’t behave an equivalent as a public block chain.
No miners aside from you means mining is more predictable;therefore,you can’t test some scenarios that occur on a public block chain.
Having no other contracts means you’ve got to deploy everything you would like to check ,including dependencies and contract libraries.
You can’t recreate a number of the general public contracts and their dependencies to check some scenarios (e.g; the DAO contracts).

The disk size requirements listed here assume you’ll be running a node with default settings,where the blockchain is “pruned” of old state. If you instead run a full”archival” node,where all state is kept disk,it will likely require quite 1TB of disc space .
Ropsten: A proof-of-work blockchain that the majority closely resembles Ethereum;you can easily mine fox-Ether.
Kovan: A proof-of-authority blockchain,started by the Parity team.Ether cannot be mined;it has got to be requested.
