Namespace

Drupal\KernelTests\Core\TypedData

Code

public function testValidation() {
  // Create a definition that specifies some AllowedValues.
  $definition = DataDefinition::create('integer')->addConstraint('AllowedValues', [
    1,
    2,
    3,
  ]);
  // Test the validation.
  $typed_data = $this->typedData
    ->create($definition, 1);
  $violations = $typed_data->validate();
  $this->assertEqual($violations->count(), 0, 'Validation passed for correct value.');
  // Test the validation when an invalid value is passed.
  $typed_data = $this->typedData
    ->create($definition, 4);
  $violations = $typed_data->validate();
  $this->assertEqual($violations->count(), 1, 'Validation failed for incorrect value.');
  // Make sure the information provided by a violation is correct.
  $violation = $violations[0];
  $this->assertEqual($violation->getMessage(), t('The value you selected is not a valid choice.'), 'The message for invalid value is correct.');
  $this->assertEqual($violation->getRoot(), $typed_data, 'Violation root is correct.');
  $this->assertEqual($violation->getInvalidValue(), 4, 'The invalid value is set correctly in the violation.');
  // Test the validation when a value of an incorrect type is passed.
  $typed_data = $this->typedData
    ->create($definition, '1');
  $violations = $typed_data->validate();
  $this->assertEquals(0, $violations->count(), 'Value is coerced to the correct type and is valid.');
