phpunit测试执行期间产生的输出-被测试代码及beStrictAboutOutputDuringTests

发布时间：2021-09-20 23:15:08编辑：雪饮阅读（）

像是上篇中有了解到测试执行期间在测试代码中有输出时候可以通过phpunit命令的--disallow-test-output参数来限制，此时当碰到测试代码中有输出时候则会抛出错误的。

那么对于被测试代码，其实也是同样的。

这里同样是以上篇中的组织测试为例

Database.php：

<?php declare(strict_types=1);
final class Database
{
    public function add()
    {
        echo "test";
        return "add success";
    }
}

这个被测代码中的add方法是有输出的

DatabaseTest.php：

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

final class DatabaseTest extends TestCase
{
    public function testAdd(): void
    {
        $db=new Database();
        $result=$db->add();
        $this->assertEquals($result,"add success");
    }
}

这个测试代码调用被测试代码进行断言，本来应该是没有问题的。
