如何测试php与mysql

<?php
require 'vendor/autoload.php';

use PHPUnit\Framework\TestCase;

class DatabaseTest extends TestCase
{
    public function testConnection()
    {
        $mysqli = new mysqli('localhost', 'user', 'password', 'database');
        $this->assertNotFalse($mysqli->connect_error);
    }
}

<?php
require 'vendor/autoload.php';

use PHPUnit\Framework\TestCase;

class UserTest extends TestCase
{
    public function testGetUser()
    {
        $mysqli = new mysqli('localhost', 'user', 'password', 'database');
        $query = "SELECT * FROM users WHERE id = 1";
        $result = $mysqli->query($query);
        $user = $result->fetch_assoc();
        $this->assertNotEmpty($user);
    }
}

<?php
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\WebDriverBy;

require_once('vendor/autoload.php');

$host = 'http://localhost:4444/wd/hub';
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities);

$driver->get('http://example.com/login');
$driver->findElement(WebDriverBy::id('username'))->sendKeys('testuser');
$driver->findElement(WebDriverBy::id('password'))->sendKeys('testpass');
$driver->findElement(WebDriverBy::id('login-button'))->click();

$driver->wait()->until(function ($driver) {
    return $driver->findElement(WebDriverBy::id('dashboard'))->isDisplayed();
});

$this->assertTrue($driver->findElement(WebDriverBy::id('dashboard'))->isDisplayed());

$driver->quit();
