The idea is to implement a simple genesis format to use in test rpc method. Each client that would like to run tests via rpc just implement this rpc methods.
The method here is the main test_setChainParams(string _config) method which would tell the client to init a test chain with the given state of accounts and genesis block config. A genesis block is a block and should have the block fields. A state is a list of accounts with it's storage and balances, nonce and code. No precompiled contracts are explicitly defined in the genesis state *(1).
The params section tells the client which mining method to use. "ProofOfWork" is a regular mining that accepts new block according to the hash calculation rules. The "ForkRules" sets which fork changes should be enabled to use on this chain. *(2). The forks are (Frontier, Homestead, ... Byzantium)
# Genesis config for running a StateTest via RPC (current version example)

We should discuss the format with other client developers and perhaps discuss what should be added here. The points *(1) and *(2) require some discussion I think.
