The UnmarshalJSON method should be updated to handle the new Hash field to maintain symmetry with the MarshalJSON method.

func (b *BatchHeader) UnmarshalJSON(data []byte) error {
	dec := new(batchHeaderEncoding)
	err := json.Unmarshal(data, dec)
	if err != nil {
		return err
	}

+	b.Hash = dec.Hash
	b.ParentHash = dec.ParentHash
	// ... rest of the fields ...
	return nil
}

Not necessary because hash is a calculated field.

@BedrockSquirrel Understood, the Hash field is computed using the Hash() method and does not need to be unmarshaled from JSON. Thank you for the clarification.

The hardcoded values for pagination (Size: 20) and batch count checks (expected 20 batches, expected more than 10 batches) may not be suitable for all test scenarios. Consider parameterizing these values to make the function more flexible and capable of handling different testing requirements.

if batchListing.BatchesData[0].Number.Cmp(batchListing.BatchesData[1].Number) < 0 {
return fmt.Errorf("expected batches to be sorted by height descending")
}

The sorting check only compares the first two batches for descending order. To ensure robustness, consider iterating over the entire list of batches to verify that they are sorted correctly by height in descending order.

The function VerifyBatchesDataAction correctly sets up a client and performs validation checks on the retrieved batch data. However, it does not check for the presence of the hash field in the batch data, which is the main objective of the PR. Consider adding a check to ensure that the hash field is present and correctly populated for each batch in the listing.
