PHPUnit使用笔记

<?php
require_once './vendor/autoload.php';
require_once './Demo.php';

use PHPUnit\Framework\TestCase;
use Mydemo\Demo;
class DemoTest extends TestCase
{
    public function testone()
    {
        //判断真假
        $this->assertTrue(Demo::add(1,2) == 3);
        //判断总数是否正确
        $this->assertEquals(5, count(Demo::fetchAll()));
        //判断结果是否包含
        $this->assertContains(1, Demo::fetchAll());
    }
}

    }
    
    public static function fetchAll()
    {
        return [1,2,3,4,5];
