---

## PR-Codex overview
This PR focuses on adding tests for the `split` functionality of a smart contract in the `thirdweb` package, ensuring that the contract behaves as expected when deployed and queried for recipient addresses and their share percentages.

### Detailed summary
- Deleted several test files related to `deploy-split` and recipient functions.
- Introduced a new test suite for the `split` contract in `split.test.ts`.
- Added tests for:
  - Deployment of the split contract.
  - Retrieving all recipient addresses.
  - Retrieving all recipients and their share percentages.
  - Retrieving the split percentage for an individual recipient.
