effects-as-data-semantic-test v1.0.0

Based on https://github.com/orourkedd/effects-as-data#usage:

Given this function:

const { actions, isFailure } = require('effects-as-data/node')
const { pluck } = require('ramda')
const getListOfNames = pluck(['name'])

const saveRepositories = function * (filename) {
  const {payload: username} = yield actions.prompt('\nEnter a github username: ')
  const repos = yield actions.httpGet(`https://api.github.com/users/${username}/repos`)
  const names = getListOfNames(repos.payload)
  yield actions.logInfo(names.join('\n'))
  return names
}

module.exports = {
  saveRepositories
}

The effects-as-data test would look like:

it('should get repositories and print names', testSaveRepositories(() => {
  const repos = [
    { name: 'foo' },
    { name: 'bar' }
  ]
  return [
    ['repos.json', actions.prompt('\nEnter a github username: ')],
    ['orourkedd', actions.httpGet('https://api.github.com/users/orourkedd/repos')],
    [repos, actions.logInfo('foo\nbar')],
    [null, ['foo', 'bar']]
  ]
}))

The effects-as-data-semantic-test test would look like:

const { args } = require('./effects-as-data-semantic-test');

it('should get repositories and print names', testSaveRepositories(() => {
  const repos = [
    { name: 'foo' },
    { name: 'bar' }
  ]
  return args('repos.json')
    .calls(actions.prompt('\nEnter a github username: ')).returns('orourkedd')
    .calls(actions.httpGet('https://api.github.com/users/orourkedd/repos')).returns(repos)
    .calls(actions.logInfo('foo\nbar')).returns(null)
    .end(['foo', 'bar']);
}))

API

args is the only function exposed initially. Should be what the functions arguments are. Returns { calls }

calls is the action/command object that is called. Returns { returns }

returns is what the action/command returns. Use calls for additional action/command calls or end to finish the function. Returns { calls, end }

end what the function returns. Returns the expected array of tuples for ead testing.
