Ethereum test node (GitHub Action)

This GitHub Action sets up a single-node and free-gas Ethereum RPC environment to automatically test smart contract projects.

Note: This action is limited only to Github Actions. It may not work in other environments.

Usage

steps:
- uses: AgustinSRG/eth-test-node-action@v6
  with:
    rpcPort: 8545 # Optional, default value is 8545. The json-RPC port
    websocketPort: 8546 # WebSockets port, by default 8546

Connecting to the node

In order to make use of the node, connect it using the HTTP interface (the node runs in the same host). Example with web3:

const web3 = new Web3("http://localhost:8545");

The Chain ID for sending transactions is 2833.

Accounts with balance

If you require accounts with balance, there are some of them defined in the genesis file, here is the full list:

Account address	Balance	Private Key

Since the min gas price is set to 0, you can make smart contract transactions at 0 cost if you specify the gas price to 0 in the transaction parameters.
