我想在 phpunit 中对控制器进行功能测试时禁用数据库写入。
在 Symfony2 的一个项目中,我使用 phpunit 测试对保存到数据库的 API 端点的 POST 调用。FOSUser
这有效,我现在在激活+时遇到回归问题HWIOAuth
。
为了避免 phpunit 将虚拟数据写入数据库,我在这里使用了这个技巧:Testing Controllers in Symfony2 with Doctrine to mock the entity manager,然后将模拟后的服务注入到测试系统的容器中。
$entityManagerMock->expects($this->once())->method('flush');
这样,当您运行测试时,数据库端点会被模拟,并且由于您可以在该问题和下面的代码中看到,它只测试了一个 flush() 被调用。
这曾经奏效。
这个测试给出了绿色条,测试了 POST 调用,没有数据保存到数据库中。
public function testPostCreatesIssue()
{
$client = static::createClient();
$entityManagerMock = $this->getMockBuilder( 'Doctrine\ORM\EntityManager' )
->setMethods( array( 'persist', 'flush' ) )
->disableOriginalConstructor()
->getMock();
$entityManagerMock->expects( $this->once() )
->method( 'flush' );
$client->getContainer()->set( 'doctrine.orm.default_entity_manager', $entityManagerMock );
$postData = array
(
'title' => 'Issues controller test, post creates issue',
'body' => 'The test tests that a post call' . PHP_EOL . 'creates a new issue' . PHP_EOL . 'in the database.' . PHP_EOL . 'UTF8: áéíóú àèìòù ñç',
'pageUrl' => 'file://Xmontero/AntiqueCrayon/MainBundle/Tests/Controller/IssuesControllerTest.php'
);
$crawler = $client->request( 'POST', '/issues/', $postData );
$response = $client->getResponse();
$this->assertEquals( Response::HTTP_CREATED, $response->getStatusCode() );
$this->assertEquals( 'application/json', $response->headers->get( 'content-type' ) );
}
那时,我只有默认的捆绑包+我自己的捆绑包AppKernel.php
问题
当我在AppKernel.php
new FOS\UserBundle\FOSUserBundle(),
new HWI\Bundle\OAuthBundle\HWIOAuthBundle(),
配置后,在我的浏览器中手动测试一切正常,包括执行上述 POST 测试的 ajax 调用。该控制器与 FOSUser 和 HWIOAuth 无关,因为该控制器在我在内核中激活这些捆绑包之前工作。
但是,尽管手动测试确实有效,但自动化测试开始失败,而Call to a member function getRepository() on a non-object
不是在我的代码行中,而是在 FOS 和 Doctrine 的内部 - 这是完整的输出:

缩小问题范围
问题是doctrine.orm.default_entity_manager
我在测试阶段为其注入模拟的服务,这就是浏览器中的手动测试没有失败的原因:没有模拟,那里。
如果我编辑我的测试不使用任何模拟,只需写入真实的数据库,它就会起作用:
->set()
要在没有模拟的情况下进行测试,我只需在容器中注释掉。并且为了避免Method was expected to be called 1 times, actually called 0 times.
我还注释掉->expects()
:
//$entityManagerMock->expects( $this->once() )
// ->method( 'flush' );
//
//$client->getContainer()->set( 'doctrine.orm.default_entity_manager', $entityManagerMock );
然后测试绿条:
xavi@bromo:/files/custom_www/antique-crayon/preproduction$ phpunit -c app --filter Post src/Xmontero/AntiqueCrayon/MainBundle/Tests/Controller/IssuesControllerTest.php
PHPUnit 3.6.10 by Sebastian Bergmann.
Configuration read from /files/custom_www/antique-crayon/preproduction/app/phpunit.xml.dist
.
Time: 0 seconds, Memory: 32.50Mb
OK (1 test, 2 assertions)
xavi@bromo:/files/custom_www/antique-crayon/preproduction$
结论
- 在
doctrine.orm.default_entity_manager
预激活 FOSUser 和 HWIOAuth 中注入模拟,工作正常 - 当在技巧中激活这些捆绑包时
AppKernel
不起作用。 - 然后我只能测试允许将真实数据写入数据库,这在测试时是不需要的。
问题
当 FOSUserBundle 和 HWIOAuthBundle 在内核中激活时,如何从 phpunit 中的测试调用控制器时禁用对数据库的写入?
谢谢!哈维。
