 The purpose of this test-generator is to provide test-vectors for the most important applications of SSZ:
  the serialization and hashing of ETH 2.0 data types
+
+#### Test case
+Example:
+```yaml

+```
+**type_name** - Name of valid Eth2.0 type from the spec   
+**value** - Field values used to create type instance  
+**serialized** - [SSZ serialization](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/simple-serialize.md#serialization) of the value      
+**root** - [hash_tree_root](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/simple-serialize.md#merkleization) of the value  
+**signing_root** - (Optional) [signing_root](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/simple-serialize.md#self-signed-containers) of the value, if type contains ``signature`` field
