Isso significa que o **FastAPI** vai esperar um corpo similar à:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

  }

  public void testParse_concurrencyLevel() {
    CacheBuilderSpec spec = parse("concurrencyLevel=32");
    assertThat(spec.initialCapacity).isNull();
    assertThat(spec.maximumSize).isNull();
    assertThat(spec.maximumWeight).isNull();
    assertThat(spec.concurrencyLevel).isEqualTo(32);
    assertThat(spec.keyStrength).isNull();
    assertThat(spec.valueStrength).isNull();

Das würde bedeuten, dass **FastAPI** einen Body wie folgt erwartet:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Wiederum, nur mit dieser Deklaration erhalten Sie von **FastAPI**:

    }

    @Test
    void testCollectArtifactDependencies() {
        Artifact artifact =
                session.createArtifact("org.codehaus.plexus", "plexus-container-default", "1.0-alpha-32", "jar");
        Node root = session.collectDependencies(artifact, PathScope.MAIN_RUNTIME);
        assertNotNull(root);
    }

    @Test

					},

    writer.write("Hello".toCharArray());
    writer.write(',');

    writer.write("Wo");
    writer.write("Whirled".toCharArray(), 3, 2);
    writer.write("Mad! Mad, I say", 2, 2);

    assertEquals("Hello, World!", builder.toString());
  }

  public void testAppendMethods() throws IOException {
    StringBuilder builder = new StringBuilder();

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

	return NewBuiltin(keyID, key)
