Like redux but with less code

import { isFunction } from 'lodash'

import createActions, { createFSA } from '../createActions'

test('return a flux standart action', () => {
  const type = 'INCREMENT'
  const action = createFSA(type)
  const error = new Error('Some error')

  const withError = action(error)
  const withPayloadAndMeta = action('foo', { foo: 'foo' })
  const justWithMeta = action(null, { foo: 'foo' })
  const justAction = action()

  expect(withError).toEqual({ type, payload: error, error: true })
  expect(withPayloadAndMeta).toEqual({ type, payload: 'foo', meta: { foo: 'foo' } })
  expect(justWithMeta).toEqual({ type, meta: { foo: 'foo' } })
  expect(justAction).toEqual({ type })
})

test('return a object with actions', () => {
  const increment = (state) => state + 1
  const decrement = (state) => state - 1

  const types = ['INCREMENT', 'DECREMENT']
  const actions = createActions(types, { increment, decrement })

  expect(isFunction(actions.increment)).toBeTruthy()
  expect(isFunction(actions.decrement)).toBeTruthy()

  expect(actions.increment()).toEqual({ type: 'INCREMENT' })
  expect(actions.decrement()).toEqual({ type: 'DECREMENT' })
})
