phpunit跳过测试与markTestSkipped

发布时间：2021-09-21 21:18:52编辑：雪饮阅读（）

有时候某些条件无法测试，就比如某项测试需要用到mysqli扩展，但是当前测试环境中没有mysqli扩展。

则测试用例写如：

DatabaseTest.php：

<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class DatabaseTest extends TestCase
{
    protected function setUp(): void
    {
        if (!extension_loaded('mysqli')) {
            $this->markTestSkipped(
                'The MySQLi extension is not available.'
            );
        }
    }

    public function testConnection(): void
    {
        $this->assertTrue(true);
    }
    public function testAdd(): void
    {
        $this->assertTrue(true);
    }
}

这里判断了，若没有mysqli扩展，则整个测试用例类的所有测试方法都不会执行测试任务。

像是这里第一次执行时候是有mysqli扩展，则执行正常：

C:\Users\Administrator\PhpstormProjects\untitled\organizing>D:\phpstudy_pro\Extensions\php\php7.3.4nts\php.exe D:\phpstudy_pro\Extensions\php\php7.3.4nts\phpunit-9.5.8.phar C:\Users\Administrator\PhpstormProjects\untitled\organizing\tests\DatabaseTest.php --verbose

PHPUnit 9.5.8 by Sebastian Bergmann and contributors.

Runtime: PHP 7.3.4

Configuration: C:\Users\Administrator\PhpstormProjects\untitled\organizing\phpunit.xml

.. 2 / 2 (100%)

Time: 00:00.009, Memory: 20.00 MB

OK (2 tests, 2 assertions)

那么当在php.ini中注释掉extension=mysqli，则再次运行就会出现了跳过测试的提示了，就不会测试本测试用例类中的所有测试方法了。
