Nehmen wir an, Sie haben eine benutzerdefinierte Exception `UnicornException`, die Sie (oder eine Bibliothek, die Sie verwenden) `raise`n könnten.

Und Sie möchten diese Exception global mit FastAPI handhaben.

        // Given
        String message = "CIFS operation failed";
        Exception cause = new RuntimeException("Root cause");

        // When
        CIFSException exception = new CIFSException(message, cause);

        // Then
        assertNotNull(exception);
        assertEquals(message, exception.getMessage());
        assertEquals(cause, exception.getCause());
    }
