当我进行测试时：
$ ./vendor/bin/simple-phpunit tests / Unit / Form / ProductFormTest.php
这是我终端的输出：
Sebastian Bergmann的PHPUnit 6.5.8
和贡献者。
运行时：PHP 7.2.4-1 + ubuntu16.04.1 + deb.sury.org + 1与Xdebug 2.7.0alpha2-dev配置：/var/www/project/phpunit.xml.dist

有1个错误：
1）App \ Tests \ Unit \ Form \ ProductFormTest :: formSubmitsValidData Symfony \ Component \ Form \ Exception \ RuntimeException：Class “App \ Entity \ Supplier”似乎不是托管的Doctrine实体。难道 你忘了映射它吗？

错误！测试：1，断言：0，错误：1。
模拟ManagerRegistry类后，此错误开始。似乎在这个单元测试中没有对存在的学说实体的映射。
是否有一种干净的方法来测试带有“Symfony \ Bridge \ Doctrine \ Form \ Type \ EntityType”字段的表单？

答案 0 :(得分：-1)
首先，您的测试用例应该从Symfony\Component\Form\Test\TypeTestCase延伸。
然后你的测试应该是这样的：
// Example heavily inspired by EntityTypeTest inside the Symfony Bridge
class ProductTypeTest extends TypeTestCase
{
/**
* @var EntityManager
*/
private $em;
/**
* @var \PHPUnit_Framework_MockObject_MockObject|ManagerRegistry
*/
private $emRegistry;
protected function setUp()
{
$this->em = DoctrineTestHelper::createTestEntityManager();
$this->emRegistry = $this->createRegistryMock('default', $this->em);
parent::setUp();
$schemaTool = new SchemaTool($this->em);
// This is the important part for you !
$classes = [$this->em->getClassMetadata(Supplier::class)];
try {
$schemaTool->dropSchema($classes);
} catch (\Exception $e) {
}
try {
$schemaTool->createSchema($classes);
} catch (\Exception $e) {
}
}
protected function createRegistryMock($name, $em)
{
$registry = $this->getMockBuilder('Doctrine\Common\Persistence\ManagerRegistry')->getMock();
$registry->expects($this->any())
->method('getManager')
->with($this->equalTo($name))
->will($this->returnValue($em));
return $registry;
}
protected function getExtensions()
{
return array_merge(parent::getExtensions(), array(
new DoctrineOrmExtension($this->emRegistry),
));
}
protected function tearDown()
{
parent::tearDown();
$this->em = null;
$this->emRegistry = null;
}
}
