phpunit匹配器never

发布时间：2021-09-23 22:51:38编辑：雪饮阅读（）

在phpunit中之前有了解过对于一个方法被调用次数的匹配，我们有使用过once，once这里是指匹配到某指定方法被执行一次，是不执行或者多执行一次都算是匹配失败。

那么今天带来的是never，这个never匹配就比较奇葩，它是匹配某个方法从未被执行。

SubjectTest.php：

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

final class SubjectTest extends TestCase
{
    public function testIdenticalObjectPassed(): void
    {

        $mock = $this->getMockBuilder(stdClass::class)
            ->setMethods(['foo'])
            ->getMock();

        $mock->expects($this->never())
            ->method('foo');

        $mock->foo();
    }
}

像是这样执行一次的就会匹配失败：
