To unit test entity assert in Symfony forms, you can follow these steps:

  1. Create a test class for your form, let's say "MyFormTypeTest". Make sure to extend the base Symfony "KernelTestCase" class.

use SymfonyBundleFrameworkBundleTestKernelTestCase;

class MyFormTypeTest extends KernelTestCase
{
    // ...
}


  1. In the setup method of your test class, boot the Symfony kernel.

public function setUp(): void
{
    self::bootKernel();
}


  1. Create a form instance and call the submit() method to trigger form validation.

public function testEntityAssert()
{
    $form = self::$kernel->getContainer()->get('form.factory')
        ->create(MyFormType::class);

    $form->submit([
        'field1' => 'value1',
        'field2' => 'value2',
        // ...
    ]);

    $this->assertTrue($form->isSynchronized());
    $this->assertTrue($form->isValid());
}


  1. Check if any entity assertion errors are being thrown by performing assertions on specific fields.

public function testEntityAssert()
{
    $form = self::$kernel->getContainer()->get('form.factory')
        ->create(MyFormType::class);

    $form->submit([
        'field1' => 'value1',
        'field2' => '',
        // ...
    ]);

    $this->assertFalse($form->isValid());

    $errors = $form->getErrors(true); // Get all form errors (including child forms)
    $this->assertCount(1, $errors); // Assert that there is one error

    $field2Errors = $form->get('field2')->getErrors(true); // Get errors of a specific field
    $this->assertCount(1, $field2Errors); // Assert that there is one error for "field2"

    $error = $field2Errors[0];
    $this->assertEquals('This value should not be blank.', $error->getMessage()); // Assert the error message
}


By following these steps, you can unit test entity assertions in Symfony forms, ensuring that the validation rules are properly applied.
