### Tags com Enums { #tags-with-enums }

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a ** mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

**FastAPI** suporta isso da mesma maneira que com strings simples:

{* ../../docs_src/path_operation_configuration/tutorial002b_py310.py hl[1,8:10,13,18] *}

        assertEquals(longMessage, exception.getMessage());
        assertNull(exception.getCause());
    }

    @Test
    public void test_getCause_withNestedExceptions() {
        // Test deeply nested exception causes
        Exception level3 = new Exception("Level 3: Database connection failed");
        Exception level2 = new Exception("Level 2: User lookup failed", level3);

        System.setProperty("var2", "value2");

        String value = "${var1}-${var2}";
        assertEquals("value1-value2", ResourceUtil.resolve(value));

        // Test nested-like patterns (but not actual nesting)
        value = "${var1${var2}}"; // The ${var2} part gets replaced first
        assertEquals("${var1value2}", ResourceUtil.resolve(value));

Here is a code block with quadruple backticks that contains triple backticks inside:
