Outra grande funcionalidade necessária pelas APIs é a validação de dados, garantindo que os dados são válidos, dados certos parâmetros. Por exemplo, que algum campo seja `int`, e não alguma string aleatória. Isso é especialmente útil para dados de entrada.

  private boolean isUserTypeFast;

  // "" means no fixed seed
  @Param("")
  private SpecialRandom random;

  @Param("false")
  private boolean sortedData;

  // the following must be set during setUp
  private Element[] queries;
  private Map<Element, Element> mapToTest;

  private Collection<Element> values;

  @BeforeExperiment
  void setUp() {
    CollectionBenchmarkSampleData sampleData =

            // Then
            assertNotNull(newResponse);
            // Verify the response was created successfully with the configuration
            // The constructor doesn't actually call any methods on the config during construction
        }
    }

By this point, it's already clear that **FastAPI** with its ideas is being useful for many people.

It is being chosen over previous alternatives for suiting many use cases better.

Many developers and teams already depend on **FastAPI** for their projects (including me and my team).

# 쿼리 매개변수와 문자열 검증 { #query-parameters-and-string-validations }

**FastAPI**를 사용하면 매개변수에 대한 추가 정보 및 검증을 선언할 수 있습니다.

이 애플리케이션을 예로 들어보겠습니다:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

쿼리 매개변수 `q`는 `str | None` 자료형입니다. 즉, `str` 자료형이지만 `None` 역시 될 수 있음을 뜻하고, 실제로 기본값은 `None`이기 때문에 FastAPI는 이 매개변수가 필수가 아니라는 것을 압니다.

/// note | 참고

FastAPI는 `q`의 기본값이 `= None`이기 때문에 필수가 아님을 압니다.

- Fixed CEL estimated cost of `replace()` to handle a zero length replacement string correctly.
