Symfony: PRE_SUBMIT表单事件的功能测试

Question

我想测试一个PRE_SUBMIT表单我的FormType类看起来像这样:

public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('productType', ChoiceType::class, [
'choices' => [
'Software' => 'software',
'Television' => 'television',
'Giftcard' => 'giftcard',
'Bitte wählen' => '',
],
])
->add('productNumber', TextType::class)
->add('title', TextType::class)
->add('submit', SubmitType::class);
$builder->addEventListener(
FormEvents::PRE_SUBMIT,
function (FormEvent $event)
{
$form = $event->getForm();
$data = $event->getData();
if ($data['productType'] === 'giftcard') {
$form->add('value', TextType::class);
}
}
);
} 

我不知道怎么做，我只能达到字段值，如果我提交的形式像这样。

$client->submitForm('Submit', [
'product[productType]' => 'giftcard',
'product[productNumber]' => 'C123123',
'product[title]' => 'TestCard',
]);

我不能像这样做第二次提交。但是表单在第一次提交后看起来很好。希望有人能帮助我或给我一些建议。

我这样做了一个预先提交的表单。现在工作得很好。如果你想用这个事件添加一个新值，你可以在第一次提交后再次打开爬虫并将值添加到表单中。

public function testRedirectAfterCreateGiftcard(): void
{
$client = static::createClient([
'debug' => false,
]);
$crawler = $client->request('GET', 'https://localhost/product/create');
$client->followRedirects();
$form = $crawler->selectButton('Submit')->form();
$values = $form->getPhpValues();
$values['product']['productType'] = 'giftcard';
$values['product']['productNumber'] = 'B122222';
$values['product']['title'] = 'Test';
$client->request($form->getMethod(), $form->getUri(), $values, $form->getPhpFiles());
$form->setValues($values);
$client->submitForm('Submit');
$form2 = $client->getCrawler()->selectButton('Submit')->form();
$values2 = $form2->getPhpValues();
$values2['product']['value'] = '25';
$form2->setValues($values2);
$client->submit($form2);
$this->assertRouteSame('app_product_view', ['productType' => 'giftcard']);
}
