PHPUnit 單元測試教程

一、官網下載對應 PHP 版本的代碼庫

https://phpunit.de/getting-started-with-phpunit.html

 

 

 

二、安裝 PHPUnit 

官網提供了兩種方法安裝

1. PHP Archive (PHAR)

➜ wget -O phpunit https://phar.phpunit.de/phpunit-8.phar

➜ chmod +x phpunit

➜ ./phpunit --version
PHPUnit 8.0.0 by Sebastian Bergmann and contributors.

 

2. Composer

➜ composer require --dev phpunit/phpunit ^8

➜ ./vendor/bin/phpunit --version
PHPUnit 8.0.0 by Sebastian Bergmann and contributors.

 

三、使用 PHPUnit 進行測試，以下代碼默認你是使用 Composer 安裝的 PHPUnit

安裝完成后在當前目錄下添加文件 EmailTest.php，文件內容如下

<?php
declare(strict_types=1);

use PHPUnit\Framework\TestCase;

final class EmailTest extends TestCase
{
    public function testCanBeCreatedFromValidEmailAddress(): void
    {
        $this->assertInstanceOf(
            Email::class,
            Email::fromString('[e-mail]')
        );
    }

    public function testCannotBeCreatedFromInvalidEmailAddress(): void
    {
        $this->expectException(InvalidArgumentException::class);

        Email::fromString('invalid');
    }

    public function testCanBeUsedAsString(): void
    {
        $this->assertEquals(
            '[e-mail]',
            Email::fromString('[e-mail]')
        );
    }
}

 

運行測試

➜ ./vendor/bin/phpunit --bootstrap vendor/autoload.php tests/EmailTest
PHPUnit 8.0.0 by Sebastian Bergmann and contributors.

...                                                                 3 / 3 (100%)
