A resposta seria algo como:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

### Configurando o `root_path` na aplicação FastAPI

    void testJoinSingleElement() {
        String result = StringUtil.join(",", "hello");
        assertEquals("hello", result);
    }

    @Test
    @DisplayName("Should join two elements with delimiter")
    void testJoinTwoElements() {
        String result = StringUtil.join(",", "hello", "world");
        assertEquals("hello,world", result);
    }

    @Test

        SmbFilenameFilter filter = (d, n) -> n.equalsIgnoreCase("hello.txt");
        assertTrue(filter.accept(dir, "Hello.TXT"));
    }

    @Test
    void acceptReturnsFalseWhenNameDoesNotMatch() throws Exception {
        SmbFile dir = Mockito.mock(SmbFile.class);
        SmbFilenameFilter filter = (d, n) -> n.equalsIgnoreCase("hello.txt");
        assertFalse(filter.accept(dir, "world.txt"));
    }

    @Test

```txt
Hello, World from Flask!
```

Und wenn Sie auf <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> gehen, sehen Sie die Response von FastAPI:

```JSON
{
    "message": "Hello World"
}

```txt
Hello, World from Flask!
```

E se você for até <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a>, você verá o retorno do FastAPI:

```JSON
{
    "message": "Hello World"
