### Fornecendo o `root_path`

Para conseguir isso, você pode usar a opção de linha de comando `--root-path` assim:

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Se você usar Hypercorn, ele também tem a opção `--root-path`.

        }
    }

    public void test_main_withHelp() {
        // Test main method with help option
        PrintStream originalErr = System.err;
        try {
            ByteArrayOutputStream errContent = new ByteArrayOutputStream();
            System.setErr(new PrintStream(errContent));

            String[] args = { "--help" };
            // Note: main calls System.exit, so we can't test it directly

   * {@link SortedMultiset#tailMultiset}, the {@code size()} and {@code iterator()} methods of
   * {@link SortedMultiset#entrySet}, and {@link SortedMultiset#remove(Object, int)}. In many
   * situations, you may wish to override {@link SortedMultiset#elementSet} to forward to this
   * implementation or a subclass thereof.
