  /**
   * Returns a mock object for the specified class using the available method.
   *
   * The getMock method does not exist in PHPUnit 6. To provide backward
   * compatibility this trait provides the getMock method and uses createMock if
   * this method is available on the parent class.
   *
   * @param string $originalClassName
   *   Name of the class to mock.
   * @param array|null $methods
   *   When provided, only methods whose names are in the array are replaced
   *   with a configurable test double. The behavior of the other methods is not
   *   changed. Providing null means that no methods will be replaced.
   * @param array $arguments
   *   Parameters to pass to the original class' constructor.
   * @param string $mockClassName
   *   Class name for the generated test double class.
   * @param bool $callOriginalConstructor
   *   Can be used to disable the call to the original class' constructor.
   * @param bool $callOriginalClone
   *   Can be used to disable the call to the original class' clone constructor.
   * @param bool $callAutoload
   *   Can be used to disable __autoload() during the generation of the test
   *   double class.
   * @param bool $cloneArguments
   *   Enables the cloning of arguments passed to mocked methods.
   * @param bool $callOriginalMethods
   *   Enables the invocation of the original methods.
   * @param object $proxyTarget
   *   Sets the proxy target.
   *
   * @see https://github.com/sebastianbergmann/phpunit/wiki/Release-Announcement-for-PHPUnit-5.4.0
   *
   * @return \PHPUnit\Framework\MockObject\MockObject
   *
   * @deprecated in drupal:8.5.0 and is removed from drupal:9.0.0.
   *   Use \Drupal\Tests\PhpunitCompatibilityTrait::createMock() instead.
