Test format: Deposit operations

A deposit is a form of an operation (or "transaction"), modifying the state.

Test case format

description: string  -- description of test case, purely for debugging purposes
pre: BeaconState     -- state before applying the deposit
deposit: Deposit     -- the deposit
post: BeaconState    -- state after applying the deposit. No value if deposit processing is aborted.

Condition

A deposits handler of the operations should process these cases, calling the implementation of the process_deposit(state, deposit) functionality described in the spec. The resulting state should match the expected post state, or if the post state is left blank, the handler should reject the inputs as invalid.
