php - 使用实体对 Symfony 表单进行单元测试

Question

我无法对内部具有“实体”字段的 Symfony 表单进行单元测试。

我找到了潜在的解决方案 here和 here ，但是我无法让它们工作。

这是我的代码:

FormsTest.php

protected function setUp()
{
    parent::setUp();

    $this->factory = Forms::createFormFactoryBuilder()
        ->addExtensions($this->getExtensions())
        ->getFormFactory();
}

protected function getExtensions()
{
    $mockEntityType = $this->getMockBuilder('Symfony\Bridge\Doctrine\Form\Type\EntityType')
        ->disableOriginalConstructor()
        ->getMock();

    $mockEntityType->expects($this->any())->method('getName')
        ->will($this->returnValue('entity'));

    return array(new PreloadedExtension(array(
        $mockEntityType->getName() => $mockEntityType,
    ), array()));
}

public function testSubmitValidData()
{
    $formData = array(
        'name' => 'Mbalmayo',
        'latitude' => 3.5165475,
        'longitude' => 11.5144015,
        'zoomLevel' => 12.0,
        'region' => 'Centre',
    );

    $type = new CitiesType();
    $form = $this->factory->create($type, null);

    $object = new Cities();
    $object->fromArray($formData);

    // submit the data to the form directly
    $form->submit($formData);

    $this->assertTrue($form->isSynchronized());
    $this->assertEquals($object, $form->getData());

    $view = $form->createView();
    $children = $view->children;

    foreach (array_keys($formData) as $key) {
        $this->assertArrayHasKey($key, $children);
    }
}

此代码基于我之前找到的解决方案。

CitiesType.php

/**
 * Builds the form data for the cities
 *
 * @param FormBuilderInterface  $builder The FormBuilderInterface to use
 * @param array                 $options The options for the form, if any
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        /* Several adds that are pointless for this problem */
        ->add('region', 'entity', array('class' => 'SmopaAgentFinderBundle:Regions',
                'property' => 'name',
                'required' => true,
                'label' => 'city.new.region',
                'query_builder' => function (EntityRepository $er) {
                    return $er->createQueryBuilder('r')
                        ->orderBy('r.name', 'ASC');
                },
                'empty_value' => 'Select city\'s region',
                'attr' => array('class' => 'new_city_combo_box')
            )
        );
}

目前，我得到这个错误:

1) FormsTest::testSubmitValidData Symfony\Component\OptionsResolver\Exception\UndefinedOptionsException: The options "attr", "class", "empty_value", "label", "property", "query_builder", "required" do not exist. Known options are: "".

我需要用测试覆盖这些表格，我完全没有想法。有什么帮助吗？

发生这种情况是因为 OptionsResolver 不知道这些选项。您的 EntityType mock 应该声明它们:

对于 Symfony 2.7:

// use Symfony\Component\OptionsResolver\OptionsResolver;

$mockEntityType->method('setDefaultOptions')->will(
    $this->returnCallback(
        function (OptionsResolver $resolver)
        {
            $resolver->setDefaults(
                array(
                    'choice_label' => null,
                    'class' => null,
                    'query_builder' => null,
                    'required' => null,
                )
            );
        }
    )
);
