Test

Introduction

This notebook provides some tests to check that the integration between Livebook and the Wargame Tool client is working correctly.

Connection with the Elixir Runtime

Run the cell bellow to check the connection with the Elixir runtime:

Context Information

The following cell outputs the current EthClient context:

EthClient.Context.all()

%{
  chain_id: 1234,
  contract: %EthClient.Contract{address: nil, functions: nil},
  etherscan_api_key: nil,
  rpc_host: "http://localhost:8545",
  user_account: %EthClient.Account{
    address: "0xafb72ccaeb7e22c8a7640f605824b0898424b3da",
    private_key: "e90d75baafee04b3d9941bd8d76abe799b391aec596515dee11a9bd55f05709c"
  }
}

Checking connection with the Local Ethereum DevNet

defmodule EthereumChainConnectionTest do
  @headers [{"content-type", "application/json"}]
  @block_number_request_body %{jsonrpc: "2.0", method: "eth_blockNumber", params: [], id: 83}

  def test!(jsonrpc_url) do
    body = Jason.encode!(@block_number_request_body)
    {:ok, res} = Tesla.post(jsonrpc_url, body, headers: @headers)
    %Tesla.Env{body: body, status: 200} = res
    %{"result" => last_block_number} = Jason.decode!(body)

    IO.puts("Current block number for #{jsonrpc_url} is #{last_block_number}")

    last_block_number
  end
end

EthereumChainConnectionTest.test!("http://ethereum:8545")
EthereumChainConnectionTest.test!("http://ethereum:8546")

Current block number for http://ethereum:8545 is 0x35
Current block number for http://ethereum:8546 is 0x35

"0x35"
