#### Viem Test Client

```ts
import { Instance, Server } from 'prool'
import { createTestClient, http } from 'viem'
import { foundry } from 'viem/chains'

const server = Server.create({
instance: Instance.anvil(),
})
await server.start()

const client = createTestClient({
chain: foundry,
mode: 'anvil',
transport: http('http://localhost:8545/1'),
})

await client.mine({ blocks: 1 })
```

The server lazily starts the Anvil instance for `/1` when the test client sends
its first request. To start it eagerly, request `http://localhost:8545/1/start`
before creating the client.
