## Testing

*Note*: The function `initialize_beacon_state_from_eth1` is modified for pure Whisk testing only.

```python
def initialize_beacon_state_from_eth1(eth1_block_hash: Hash32,
eth1_timestamp: uint64,
deposits: Sequence[Deposit],
execution_payload_header: ExecutionPayloadHeader=ExecutionPayloadHeader()
) -> BeaconState:
state_capella = capella.initialize_beacon_state_from_eth1(
eth1_block_hash,
eth1_timestamp,
deposits,
execution_payload_header,
)
state = upgrade_to_whisk(state_capella)
state.fork.previous_version = WHISK_FORK_VERSION
state.fork.current_version = WHISK_FORK_VERSION
return state
```
