进行单元测试我是用phpunit和GuzzleHttp。

一、安装phpunit

composer require phpunit/phpunit

二、安装GuzzleHttp

composer require guzzlehttp/guzzle

三、修改composer.json文件

{
    "require": {
        "phpunit/phpunit": "^8.5",
        "guzzlehttp/guzzle": "~6.0"
    },
    "autoload": {
        "psr-4": {
            "app\\": "application/",
            "basic\\": "extend/basic",
            "traits\\": "extend/traits",
            "tests\\": "tests/"
        }
    }
}

修改完后，更新下composer

composer dumpautoload

四、添加或修改phpunit.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="tests/autoload.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory suffix=".php">./tests/</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist>
            <directory suffix=".php">application/</directory>
        </whitelist>
    </filter>
    <php>
        <server name='HTTP_ACCEPT' value='*' />
    </php>
</phpunit>

bootstrap参数栏，是用来加载tp机制的。

五、设置加载TP机制，也就是bootstrap参数栏的tests目录下的autoload.php

<?php
use think\Config;
use think\Db;
// 初始化app
define('APP_PATH', dirname(__DIR__) . '/application/');
define('VENDOR_PATH', APP_PATH . 'vendor' . DIRECTORY_SEPARATOR); // 让tp不用自己的载入机制，而使用composer的autoload
require_once dirname(__DIR__) . '/vendor/autoload.php';

include dirname(__DIR__) . '/core/base.php';

include dirname(__DIR__) . '/core/helper.php';
Config::load(APP_PATH . '/database.php', 'database');

相当于进行单元测试的入口。

六、开始单元测试编写啦，也就是在tests目录创建个XxApiTest.php

<?php
namespace tests;

use PHPUnit\Framework\TestCase;
use GuzzleHttp\Client;

class XxApiTest extends TestCase
{

    public $client;

     public function __construct(?string $name = null, array $data = [], string $dataName = '')
    {
        parent::__construct($name, $data, $dataName);
        $this->client = new Client([
            'base_uri' => 'https://www.baidu.com/',
            'verify' => false,
            'headers' => [
                'Accept'     => '*',
            ]
        ]);
    }
    
    public function testXxApi() {  
       
        $resp = $this->client->request('POST', 'XxApi', [
                    'form_params' => [
                        'token' => '123456'
                    ],
                ]);
     
        $this->assertEquals(200, $resp->getStatusCode());
    }
}

七、相关单元测试写完后，在根目录下执行phpunit命令就行了

//测试所有
phpunit
