But **FastAPI** will know that it has to solve `query_extractor` first, to pass the results of that to `query_or_cookie_extractor` while calling it.

* Calling your dependency ("dependable") function with the correct parameters.
* Get the result from your function.
* Assign that result to the parameter in your *path operation function*.

This way, each project will have its own virtual environment (`.venv` directory) with its own packages.

    val headers = headersBuilder.build()
    server.enqueue(MockResponse(headers = headers))
    val response = getResponse(newRequest("/"))
    assertThat(response.code).isEqualTo(200)
    assertThat(response.header("a\tb")).isEqualTo("c\u007fd")

가상 환경은 전역 환경과 매우 유사한 하나의 **디렉터리**이며, 그 안에 해당 프로젝트를 위한 패키지들을 설치할 수 있습니다.

이렇게 하면 각 프로젝트는 자체적인 가상 환경(`.venv` 디렉터리)을 가지게 되며, 그 안에 해당 프로젝트 전용 패키지들을 보유하게 됩니다.
