Steps

The steps that are to be run are to be defined inside a json file. Here's an example of how one such file might look like:

{
    "config": {
        "pem": "~/devnet-wallet.pem",
        "proxy": "https://testnet-api.elrond.com",
        "chain": "T"
    },
    "steps": [
        {
            "type": "deploy",
            "options": {
                "path": "~/src/nerds/carpathian/raffle",
                "arguments": "0x0000000000000000000100000000000000000000000000000000000010ffffff",
                "gas_limit": 600000000,
                "delay": 10000
            }
        },
        {
            "type": "transaction",
            "options": {
                "gas_limit": 20000000,
                "function": "pause",
                "delay": 10000
            }
        },
        {
            "type": "transaction",
            "options": {
                "arguments": "0x623a315b",
                "gas_limit": 20000000,
                "function": "setNewDeadline",
                "delay": 10000
            }
        },
        {
            "type": "transaction",
            "options": {
                "gas_limit": 20000000,
                "function": "unpause",
                "delay": 10000
            }
        },
        {
            "type": "query",
            "options": {
                "function": "getWinners"
            }
        },
        {
            "type": "test",
            "options": {
                "path": "~/test-module.ex"
            }
        }
    ]
}

Tests

Using a test step allows writing custom tests using ExUnit. Getting the context can be done using the Context.get() function, with the Context module being injected at runtime. An example test could look like this:

defmodule TestModule do
  use ExUnit.Case

    test "Proxy is correct" do
        assert Context.get()[:proxy] == "https://testnet-api.elrond.com"
    end

    test "Chain id is correct" do
        assert Context.get()[:chain] == "T"
    end
end
