## Datenklassen in verschachtelten Datenstrukturen { #dataclasses-in-nested-data-structures }

Sie können `dataclasses` auch mit anderen Typannotationen kombinieren, um verschachtelte Datenstrukturen zu erstellen.

/**
 * Test Fixtures Plugin.
 *
 * Configures the Project as a test fixtures producer if `src/testFixtures` is a directory:
 * - adds a new `testFixtures` source set which should contain utilities/fixtures to assist in unit testing
 *   classes from the main source set,
 * - the test fixtures are automatically made available to the test classpath.

FastAPI 애플리케이션에 요청을 보내는 것 외에도 테스트에서 `async` 함수를 호출하고 싶다면 (예: 비동기 데이터베이스 함수), 심화 튜토리얼의 [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} 를 참조하세요.

///

## 테스트 분리하기

실제 애플리케이션에서는 테스트를 별도의 파일로 나누는 경우가 많습니다.


그리고 **FastAPI** 애플리케이션도 여러 파일이나 모듈 등으로 구성될 수 있습니다.
