The [SliceAt(typ Type, p unsafe.Pointer, len int)] function
returns a Value representing a slice whose underlying array starts

1. Script the mocks.
2. Run application code.
3. Verify that the expected requests were made.

Here's a complete example:

```java
public void test() throws Exception {
  // Create a MockWebServer. These are lean enough that you can create a new
  // instance for every unit test.
  MockWebServer server = new MockWebServer();

  // Schedule some responses.
  server.enqueue(new MockResponse().setBody("hello, world!"));

Isso é chamado de "assíncrono" porquê o computador / programa não tem que ser "sincronizado" com a tarefa lenta, esperando pelo exato momento que a tarefa finalize, enquanto não faz nada, para ser capaz de pegar o resultado da tarefa e dar continuidade ao trabalho.
