phpunit标注-testdox-动态的替换描述

发布时间：2021-10-07 22:36:08编辑：雪饮阅读（）

 上篇就说testdox标注是为了指定生成敏捷文档句子时使用的替换描述。那么当@testdox 标注在方法级别和 @dataProvider（数据供给器） 联用，可以在替换描述中将方法参数用作占位符以形成动态的替换描述。

实例如：
MyTest.php：

<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;
final class MyTest extends TestCase
{
    /**
     * @dataProvider additionProvider
     * @testdox Adding $a to $b results in $expected
     */
    public function testAdd($a, $b, $expected)
    {
        $this->assertSame($expected, $a + $b);
    }

    public function additionProvider()
    {
        return [
            [0, 0, 0],
            [0, 1, 1],
            [1, 0, 1],
            [1, 1, 3]
        ];
    }
}

运行结果如：
