react專案中整合redux

npm install redux

npm install react-redux

npm install redux-thunk

生成store

在專案初始化預設index檔案中設定./index.js

import

from
'redux'
const store =
createstore
(fn)

import

from
'redux'
import index from
'./main/reducers/index'
import page1 from
'./main/reducers/page1'
const storetree =
combinereducers()
export
default storetree;

import from 'react-redux'

const list =

connect
( mapstatetoprops,
mapdispatchtoprops
)//mapstate負責輸入邏輯，將state對映到ui元件的引數（props）
//mapdispatchtoprops負責輸出邏輯，將使用者對ui元件的操作對映為action

函式：建立乙個從（外部state到props）的對映關係

const

mapstatetoprops
= state =>
}

用來建立 ui 元件的引數到store.dispatch方法的對映。也就是說，它定義了哪些使用者的操作應該當作 action，傳給 store

在專案初始化預設index檔案中設定./index.js

讓容器元件拿到state

import

from
'react-redux'
import
from
'redux'
import reducerfile from
'./reducers'
let store =
createstore
(reducerfile)
render
(>
>
<
/provider>
document.
getelementbyid
('root'
))

//根目錄index.js檔案

import react from
'react'
;import reactdom from
'react-dom'
;import
'./common/assets/style/style.css'
;import
*as serviceworker from
'./serviceworker'
;//redux引入檔案和模組
import storetree from
'./store'
;import
from
'react-redux'
;import
from
'redux'
;import thunk from
'redux-thunk'
;import
from
'react-router-dom'
;const store =
createstore
(storetree,
(thunk));
reactdom.
render
(>
>
<
/router>
<
/provider>
, document.
getelementbyid
('root'))
;// unregister() to register() below. note this comes with some pitfalls.
// learn more about service workers: 
serviceworker.
unregister()
;

//根目錄下新建reduxstore.js

import
from
'redux'
import index from
'./main/reducers/index'
import page1 from
'./main/reducers/page1'
const storetree =
combinereducers()
export
default storetree;

// ../constants/index.js

export
const
settest
="settest"
;

// ../actions/index.js

import
from
'../constants/index'
export
const
settest
=(test)
=>)}
}

// ../reducer/index.js

import
from
'../constants/index'
const
init_state
=export
default
function
setportlist
(state=
init_state
, action)
default
:return state
}}

// pages/index.js

import
from
'react-redux'
import
from
'../actions/index'
const
mapstatetoprops
= state =>
}@connect
(mapstatetoprops,
)class
index
extends
component

const
=require
('customize-cra');
module.exports =

在專案中整合測試

使用小規模測試降低風險 開發人員編寫 和缺陷 tdd是在專案中整合測試最簡便的方式 單元測試不是萬能藥 使用多種測試技巧 確定每個團隊成員在測試中的角色 測試人員稱職嗎 一流的測試人員具有足夠的創造力，編碼工作之前，就能評估系統的設計和架構 編寫 過程中，測試人員會設計和實現他們的測試元件 會衡量測...
