# Test format: BLS sign message

Message signing with BLS should produce a signature.

## Test case format

The test data is declared in a `data.yaml` file:

```yaml
input:
  privkey: bytes32 -- the private key used for signing
  message: bytes32 -- input message to sign (a hash)
  domain: bytes8   -- the BLS domain
output: bytes96    -- expected signature
```

All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with `0x`.


## Condition

The `sign_msg` handler should sign the given `message`, with `domain`, using the given `privkey`, and the result should match the expected `output`.
