我模拟一个类的函数，并试图根据给定对象（模拟函数的参数）的属性返回不同的值

在我的代码下面，有一些评论：

代码

use AppBundle\Entity\Campaign;
use Monolog\Logger;
use PHPUnit\Framework\TestCase;

class FacebookHelperTest extends TestCase {
    public function testIfStatusSyncIsSetCorrectly() {
        $campaign = new Campaign();

        /** @var \PHPUnit_Framework_MockObject_MockObject|Logger $logger */
        $logger = $this->createMock(Logger::class);

        /** @var \PHPUnit_Framework_MockObject_MockObject|FacebookHelper $helper */
        $builder = $this->getMockBuilder(FacebookHelper::class)->disableOriginalConstructor()->setMethods(['getExternalCampaignData']);
        $helper = $builder->getMock();

        $helper->expects($this->exactly(3))
            ->method('getExternalCampaignData')
            ->withConsecutive(
                [$this->callback(function(Campaign $campaign) { var_dump($campaign->getFbCampaignId(), "expecting 1"); return $campaign->getFbCampaignId() == 1; })],
                [$this->callback(function(Campaign $campaign) { var_dump($campaign->getFbCampaignId(), "expecting 2"); return $campaign->getFbCampaignId() == 2; })],
                [$this->callback(function(Campaign $campaign) { var_dump($campaign->getFbCampaignId(), "expecting 3"); return $campaign->getFbCampaignId() == 3; })]
            )
            ->willReturnOnConsecutiveCalls(
                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ACTIVE]],
                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ACTIVE]],
                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ARCHIVED]]
            );

        $campaign->setFbCampaignId(1);
        $campaign->setStatus('active');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);
        $this->assertFalse($modifiedCampaign->getSettings('fb_status_out_of_sync'));

        $campaign->setFbCampaignId(2);
        $campaign->setStatus('paused');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);
        $this->assertTrue($modifiedCampaign->getSettings('fb_status_out_of_sync'));

        $campaign->setFbCampaignId(3);
        $campaign->setStatus('paused');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);
        $this->assertTrue($modifiedCampaign->getSettings('fb_status_out_of_sync'));
    }
}

当我运行上面的单元测试时，一切似乎都正常工作。除了行为有点奇怪之外，回调调用的次数太多了

我已经发现了一个可能导致以下情况的错误：因此，我将phpunit更新为5.7.20版，希望这个问题在那里得到解决

或者我需要用不同的方法

PHPunit的结果

        $builder = $this->getMockBuilder(FacebookHelper::class)->disableOriginalConstructor()->setMethods(['getExternalCampaignData']);
        $helper = $builder->getMock();

        $helper->expects($this->exactly(3))

                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ARCHIVED]]
            );

        $campaign->setFbCampaignId(1);
        $campaign->setStatus('active');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);

    }

Oke，所以在大量搜索之后，我检查了phpunit测试本身的单元测试（paradox:p？），最后发现了它是如何工作的

解决方案

use AppBundle\Entity\Campaign;
use Monolog\Logger;
use PHPUnit\Framework\TestCase;

class FacebookHelperTest extends TestCase {
    public function testIfStatusSyncIsSetCorrectly() {
        $campaign = new Campaign();

        /** @var \PHPUnit_Framework_MockObject_MockObject|Logger $logger */
        $logger = $this->createMock(Logger::class);

        /** @var \PHPUnit_Framework_MockObject_MockObject|FacebookHelper $helper */
        $builder = $this->getMockBuilder(FacebookHelper::class)->disableOriginalConstructor()->setMethods(['getExternalCampaignData']);
        $helper = $builder->getMock();

        $helper->expects($this->exactly(3))
            ->method('getExternalCampaignData')
            ->withConsecutive(
                [$this->callback(function(Campaign $campaign) { var_dump($campaign->getFbCampaignId(), "expecting 1"); return $campaign->getFbCampaignId() == 1; })],
                [$this->callback(function(Campaign $campaign) { var_dump($campaign->getFbCampaignId(), "expecting 2"); return $campaign->getFbCampaignId() == 2; })],
                [$this->callback(function(Campaign $campaign) { var_dump($campaign->getFbCampaignId(), "expecting 3"); return $campaign->getFbCampaignId() == 3; })]
            )
            ->willReturnOnConsecutiveCalls(
                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ACTIVE]],
                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ACTIVE]],
                ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ARCHIVED]]
            );

        $campaign->setFbCampaignId(1);
        $campaign->setStatus('active');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);
        $this->assertFalse($modifiedCampaign->getSettings('fb_status_out_of_sync'));

        $campaign->setFbCampaignId(2);
        $campaign->setStatus('paused');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);
        $this->assertTrue($modifiedCampaign->getSettings('fb_status_out_of_sync'));

        $campaign->setFbCampaignId(3);
        $campaign->setStatus('paused');

        $modifiedCampaign = $helper->modifyCampaignIfNeeded($campaign, $logger);
        $this->assertTrue($modifiedCampaign->getSettings('fb_status_out_of_sync'));
    }
}

$helper->expects($this->exactly(3))
            ->method('getExternalCampaignData')
            ->will(
                $this->returnCallback(
                    function(Campaign $campaign) {
                        if($campaign->getFbCampaignId() == 1) return ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ACTIVE]];
                        if($campaign->getFbCampaignId() == 2) return ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ACTIVE]];
                        if($campaign->getFbCampaignId() == 3) return ['campaign' => ['status' => FacebookHelper::CAMPAIGN_STATUS_ARCHIVED]];
                    }
                )
            );

您可以将此简化为

$statuses = [
    1 => FacebookHelper::CAMPAIGN_STATUS_ACTIVE,
    2 => FacebookHelper::CAMPAIGN_STATUS_ACTIVE,
    3 => FacebookHelper::CAMPAIGN_STATUS_ARCHIVED,
];

$helper
    ->expects($this->exactly(count($statuses))
    ->method('getExternalCampaignData')
    ->willReturnCallback(function(Campaign $campaign) use ($statuses) {
        $id = $campaign->getFbCampaignId();

        if (!array_key_exists($id, $statuses)) {
            return;
        }

        return [
            'campaign' => [
                'status' => $statuses[$id],
            ],
        ];
    });
