Operations tests

The different kinds of operations ("transactions") are tested individually with test handlers.

Test case format

description: string                    -- description of test case, purely for debugging purposes
bls_setting: int                       -- see general test-format spec.
pre: BeaconState                       -- state before applying the operation
<operation-name>: <operation-object>   -- the YAML encoded operation, e.g. a "ProposerSlashing", or "Deposit".
post: BeaconState                      -- state after applying the operation. No value if operation processing is aborted.

Condition

A handler of the operations test-runner should process these cases, calling the corresponding processing implementation.

Operations:

operation-name	operation-object	input name	processing call
attestation	Attestation	attestation	process_attestation(state, attestation)
attester_slashing	AttesterSlashing	attester_slashing	process_attester_slashing(state, attester_slashing)
block_header	Block	block	process_block_header(state, block)
deposit	Deposit	deposit	process_deposit(state, deposit)
proposer_slashing	ProposerSlashing	proposer_slashing	process_proposer_slashing(state, proposer_slashing)
transfer	Transfer	transfer	process_transfer(state, transfer)
voluntary_exit	VoluntaryExit	voluntary_exit	process_voluntary_exit(state, voluntary_exit)

Note that block_header is not strictly an operation (and is a full Block), but processed in the same manner, and hence included here.

The resulting state should match the expected post state, or if the post state is left blank, the handler should reject the input operation as invalid.
