## Установка пользовательских обработчиков исключений

Вы можете добавить пользовательские обработчики исключений с помощью <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">то же самое исключение - утилиты от Starlette</a>.

Допустим, у вас есть пользовательское исключение `UnicornException`, которое вы (или используемая вами библиотека) можете `вызвать`.

        boolean log = !(service instanceof NoOpService);
        /*
         * We have already exposed startup exceptions to the user in the form of suppressed
         * exceptions. We don't need to log those exceptions again.
         */
        log &= from != State.STARTING;
        if (log) {
          logger
              .get()
              .log(

    }

    @Test
    @DisplayName("Delegation should handle exceptions from delegate")
    void testExceptionHandling() {
        // Given
        RuntimeException testException = new RuntimeException("Test exception");
        when(mockDelegate.getResponseTimeout()).thenThrow(testException);

## Instalando manipuladores de exceções customizados

Você pode adicionar manipuladores de exceção customizados com <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">a mesma seção de utilidade de exceções presentes no Starlette</a>

        final Exception cause = new RuntimeException("Test cause");

        // Execute
        final SsoMessageException exception = new SsoMessageException(messageCode, null, cause);

        // Verify
        assertNotNull(exception);
        assertNull(exception.getMessage());
        assertEquals(cause, exception.getCause());
        assertEquals(messageCode, exception.getMessageCode());
    }
