# Test Client \[A function to create a Test Client]

A Test Client is an interface to "test" JSON-RPC API methods accessible through a local Ethereum test node such as [Anvil](https://getfoundry.sh/anvil/overview) or [Hardhat](https://hardhat.org/) such as mining blocks, impersonating accounts, setting fees, etc through [Test Actions](/docs/actions/test/introduction).

The `createTestClient` function sets up a Test RPC Client with a given [Transport](/docs/clients/intro).

## Usage

Initialize a Client with your desired [Chain](/docs/chains/introduction), [Transport](/docs/clients/intro) (e.g. `http`) and [mode](#mode) (e.g. `"anvil"`).

### Extending with Public & Wallet Actions

When interacting with a Ethereum test node, you may also find yourself wanting to interact with [Public Actions](/docs/actions/public/introduction) and [Wallet Actions](/docs/actions/wallet/introduction) with the same `chain` and `transport`. Instead of creating three different Clients, you can instead just extend the Test Client with those actions:

```ts twoslash
// @twoslash-cache:
