Run the tests with the following commands:

For L2
```bash
forge test -vvvv --contracts scripts/upgrades --mc PostSherlockL2 --rpc-url $ETH_RPC_URL
```

For L1
```bash
forge test -vvvv --contracts scripts/upgrades --mc PostSherlockL1 --rpc-url $ETH_RPC_URL
```

Ensure that the `ETH_RPC_URL` env var is set for the correct env var.
