phpunit对单个测试使用多个数据供给器

发布时间：2021-09-13 21:54:49编辑：雪饮阅读（）

 上篇了解了”在同一个测试中组合 @depends 和 @dataProvider”

https://www.gaojiupan.cn/manshenghuo/chengxurensheng/3991.html
那么如果是同一个测试使用多个数据供给器呢？
DataTest.php：
<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class DataTest extends TestCase
{
    /**
     * @dataProvider additionWithNonNegativeNumbersProvider
     * @dataProvider additionWithNegativeNumbersProvider
     */
    public function testAdd(int $a, int $b, int $expected): void
    {
        print_r(func_get_args());
        echo "\r\n";
        $this->assertSame($expected, $a + $b);
    }

    public function additionWithNonNegativeNumbersProvider(): array
    {
        return [
            [0, 1, 1],
            [1, 0, 1],
            [1, 1, 3]
        ];
    }

    public function additionWithNegativeNumbersProvider(): array
    {
        return [
            [-1, 1, 0],
            [-1, -1, -2],
            [1, -1, 0]
        ];
    }
}
运行效果如：

可以看到这多个数据供给器就相当于多组数据，则使用多组数据的这个测试方法则会按dataProvider定义的语法顺序进行顺序的遍历每组数据进行测试。
那么为了证明确实是按顺序的，我们可以将这里dataProvider定义的顺序调整下。

/**
 * @dataProvider additionWithNegativeNumbersProvider
 * @dataProvider additionWithNonNegativeNumbersProvider
 */
public function testAdd(int $a, int $b, int $expected): void
{
    print_r(func_get_args());
    echo "\r\n";
    $this->assertSame($expected, $a + $b);
}

调整成这样后，我们再次运行：

可以看到这次是先运行有负数的这组数据了
