If you want to test the themes of your forms, you may want to make your test extends the
:class:`Symfony\\Bridge\\Twig\\Test\\FormLayoutTestCase` class. This saves a lot of
boilerplate and code duplication by implementing the
:class:`Symfony\\Component\\Form\\Test\\FormIntegrationTestCase` methods for you.

:method:`Symfony\\Bridge\\Twig\\Test\\FormLayoutTestCase::getTemplatePaths`, the
:method:`Symfony\\Bridge\\Twig\\Test\\FormLayoutTestCase::getTwigExtensions` and
the :method:`Symfony\\Bridge\\Twig\\Test\\FormLayoutTestCase::getThemes` methods.

introduced in Symfony 6.4.
