Useful scripts to execute from your CI runner. For example, post to Slack and GitHub when your build completes:

const log = require('../../lib/effects/log');
const exec = require('../../lib/effects/exec');
const createCi = require('../../lib/createCi');
const executeCommand = require('../../lib/exec');

jest.mock('../../lib/effects/log');
jest.mock('../../lib/effects/exec');
