Crie funções com um nome que comece com `test_` (essa é a convenção padrão do `pytest`).

Use o objeto `TestClient` da mesma forma que você faz com `httpx`.

Escreva instruções `assert` simples com as expressões Python padrão que você precisa verificar (novamente, `pytest` padrão).

## 검증 추가

매개변수 `min_length` 또한 추가할 수 있습니다:

{* ../../docs_src/query_params_str_validations/tutorial003.py hl[9] *}

## 정규식 추가

매개변수와 일치해야 하는 <abbr title="정규표현식(regular expression), regex 또는 regexp는 문자열 조회 패턴을 정의하는 문자들의 순열입니다">정규표현식</abbr>을 정의할 수 있습니다:

{* ../../docs_src/query_params_str_validations/tutorial004.py hl[10] *}

이 특정 정규표현식은 전달 받은 매개변수 값을 검사합니다:

* `^`: 이전에 문자가 없고 뒤따르는 문자로 시작합니다.

// newline.
