So i am making a school project with javaFX and i need to make test with junit 5. But when i try to run my test i get an ExceptionInitializeError because the “ToolKit” is not initialized. How can i initialize this toolkit?

public class RegisterTest {

    private Register register;
    private User user;

    @BeforeEach
    public void setUp() {
        register = new Register();
        register.username = new TextField();
        register.email = new TextField();
        register.password = new TextField();
        register.confirmPassword = new TextField();
        user = mock(User.class);

    }

    @Test
    public void testValidUser() {
        when(user.checkNewUsername(anyString())).thenReturn(true);
        when(user.checkNewEmail(anyString())).thenReturn(true);
        when(user.checkNewPassword(anyString())).thenReturn(true);

        assertTrue(register.validUser());
    }

i asked chatgtp and i gave me an initializor that runs @Beforeall.

@BeforeAll
    public static void initToolkit() {
        new JFXPanel(); // Initializes the JavaFX toolkit
    }
