 2 | Dead Simple Chaos/Property Testing with Redux
 3 | 
 4 | This randomly chooses an action from an array 100,000 times and dispatches it to a store with a hook on each repetition.
 5 | 
 6 | ##Setup
 7 | 
 8 | `npm i --save-dev redux-chaos`
 9 | ```javascript
10 | import { chaos } from 'redux-chaos'
11 | ```
12 | 
13 | ###chaos `(Store: ReduxStore, Actions: Array<Object | Function> | Object, Each: ?Function)`
14 | 
15 | Store: any redux store
16 | 
17 | Actions: your object of actions or an array of your actions
18 | 
19 | If you have an actions file, you can simply use `import * as actions from './actions'` for the actions.
20 | 
21 | Each: `(prevState: any, nextState: any, action: Object | Function): void`
22 | 
23 | Each is executed every iteration and given the parameters above, self explanatory.
24 | 
25 | ##Example
26 | 
27 | ```javascript
28 | import { chaos } from 'redux-chaos'
29 | 
30 | function counter(state = {count: 0, other: ''}, action) {
31 |   switch (action.type) {
32 |     case 'INCREMENT_COUNTER':
33 |       return {
34 | 				count: state.count + 1,
35 | 				other: state.other
36 | 			}
37 |     case 'DECREMENT_COUNTER':
38 |       return {
39 | 				count: state.count - 1,
40 | 				other: state.other
41 | 			}
42 | 		case 'AYYY': 
43 | 			return {
44 | 				count: state.count,
45 | 				other: state.other.length >= 50 ? state.other : state.other + 'lo'
46 | 			}
47 |     default:
48 |       return state
49 |   }
50 | }
51 | 
52 | const mockStore = createStore(counter)
53 | 
54 | function eachTime (prevState, nextState, action) {
55 | 	if(action.type === 'INCREMENT_COUNTER')
56 | 		expect(nextState.count).to.be.above(prevState.count)
57 | 	if(action.type === 'DECREMENT_COUNTER')
58 | 		expect(nextState.count).to.be.below(prevState.count)
59 | 		
60 | 	expect(nextState.other).to.have.length.below(51)
61 | }
62 | 
63 | describe('Redux', () => {
64 | 	it('things', () => {
65 | 		chaos(mockStore, [
66 | 			{type: 'INCREMENT_COUNTER'}, 
67 | 			{type: 'DECREMENT_COUNTER'}, 
68 | 			{type: 'AYYY'}], 
69 | 			eachTime)
70 | 	})
71 | })
72 | ```
73 | 
74 | Very simple.
