摘要：另外，與模板方法將分別在測(cè)試用例類(lèi)的第一個(gè)測(cè)試運(yùn)行之前和測(cè)試用例類(lèi)的最后一個(gè)測(cè)試運(yùn)行之后調(diào)用。

本系列教程所有的PHPUnit測(cè)試基于PHPUnit6.5.9版本，Lumen 5.5框架

PHPUnit測(cè)試一個(gè)文件類(lèi)的生命周期

理解PHPUnit加載機(jī)制（Lumen版）

PHPUnit自動(dòng)測(cè)試文件會(huì)自動(dòng)加載引入（include file）

PHPUnit去啟動(dòng)setUp方法，Lumen里重寫(xiě)了setUp，加載了bootstrap/app.php

app.php加載了composer的autoload，借此你項(xiàng)目所有自動(dòng)加載環(huán)境都有了，不過(guò)不包含tests目錄

至此我們引入了我們需要構(gòu)建自己的自動(dòng)加載類(lèi)

增加tests的自動(dòng)加載 我們需要給tests下的測(cè)試用例創(chuàng)建類(lèi)似下面的結(jié)構(gòu)

├── BaseCase.php 重寫(xiě)過(guò)Lumen基類(lèi)的測(cè)試基類(lèi)，用于我們用這個(gè)基類(lèi)做測(cè)試基類(lèi)，后續(xù)會(huì)說(shuō)明
