Cada seção constrói, gradualmente, sobre as anteriores, mas sua estrutura são tópicos separados, para que você possa ir a qualquer um específico e resolver suas necessidades específicas de API.

Ele também foi construído para servir como uma referência futura, então você pode voltar e ver exatamente o que você precisa.

## Rode o código { #run-the-code }

    ArbitraryInstances.get(Stopwatch.class).start();
    assertThat(ArbitraryInstances.get(Ticker.class)).isNotNull();
    assertFreshInstanceReturned(Random.class);
    assertEquals(
        ArbitraryInstances.get(Random.class).nextInt(),
        ArbitraryInstances.get(Random.class).nextInt());
  }

  public void testGet_concurrent() {
    assertTrue(ArbitraryInstances.get(BlockingDeque.class).isEmpty());

Por exemplo, você poderia declarar que algo pode ser `str` ou `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

O `typing` também tem um atalho para declarar que algo pode ser `None`, com `Optional`.

Aqui vai uma dica do meu ponto de vista bem subjetivo:

* 🚨 Evite usar `Optional[SomeType]`
* Em vez disso ✨ use **`Union[SomeType, None]`** ✨.
