# Genesis creation testing
Tests the initialization of a genesis state based on Eth1 data.
## Test case format
2021-03-22 01:50:05 +00:00
### `eth1.yaml`
2019-07-30 12:09:20 +00:00
2021-03-22 01:50:05 +00:00
```yaml
eth1_block_hash: Bytes32 -- A `Bytes32` hex encoded, with prefix 0x. The root of the Eth1 block. E.g. "0x4242424242424242424242424242424242424242424242424242424242424242"
eth1_timestamp: int -- An integer. The timestamp of the block, in seconds.
```
2019-07-30 12:09:20 +00:00
### `meta.yaml`
A yaml file to help read the deposit count:
2019-07-30 13:06:15 +00:00
```yaml
2021-03-15 16:38:30 +00:00
description: string -- Optional. Description of test case, purely for debugging purposes.
2019-07-30 12:09:20 +00:00
deposits_count: int -- Amount of deposits.
```
2020-10-08 19:02:18 +00:00
### `deposits_<index>.ssz_snappy`
2019-07-30 13:06:15 +00:00
A series of files, with `<index>` in range `[0, deposits_count)` . Deposits need to be processed in order.
2020-10-08 19:02:18 +00:00
Each file is a SSZ-snappy encoded `Deposit` object.
2019-07-30 12:09:20 +00:00
2020-10-08 19:02:18 +00:00
### `state.ssz_snappy`
2019-07-30 12:09:20 +00:00
2021-03-13 04:42:51 +00:00
The expected genesis state. An SSZ-snappy encoded `BeaconState` object.
2019-07-30 12:09:20 +00:00
## Processing
2019-06-30 12:58:53 +00:00
To process this test, build a genesis state with the provided `eth1_block_hash` , `eth1_timestamp` and `deposits` :
`initialize_beacon_state_from_eth1(eth1_block_hash, eth1_timestamp, deposits)` ,
as described in the Beacon Chain specification.
## Condition
The resulting state should match the expected `state` .
