Cualquier función que sea válida para usar con:

sería válida para usar como una dependencia en **FastAPI**.

    Random random = new Random();
    for (int i = 0; i < 100; i++) {
      byte[] bytes = new byte[64];
      random.nextBytes(bytes);
      String s = new String(bytes, UTF_16LE); // so all random strings are valid
      assertEquals(
          new Sink(4).putUnencodedChars(s).hash(),
          new Sink(4).putBytes(s.getBytes(UTF_16LE)).hash());
      assertEquals(

So, `0.5` would be a valid value. But `0.0` or `0` would not.

O parâmetro `name` **ainda é obrigatório** (não *opicional*) porque ele não possui um valor padrão. Mesmo assim, `name` aceita `None` como valor:

```Python
say_hi(name=None)  # This works, None is valid 🎉
```

A boa notícia é, quando você estiver no Python 3.10 você não precisará se preocupar mais com isso, pois você poderá simplesmente utilizar o `|` para definir uniões de tipos:

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

    public void test_constructor_withNullMessageAndValidCause() {
        // Test constructor with null message and valid cause
        Throwable cause = new IllegalArgumentException("Invalid argument");
        SearchEngineClientException exception = new SearchEngineClientException(null, cause);

        assertNotNull(exception);
