        env:
          GITHUB_CONTEXT: ${{ toJson(github) }}
        run: echo "$GITHUB_CONTEXT"
      - uses: actions/setup-python@v5
        with:
          python-version: '3.9'

      - run: pip install smokeshow

      - uses: dawidd6/action-download-artifact@v3.1.4
        with:
          github_token: ${{ secrets.FASTAPI_SMOKESHOW_DOWNLOAD_ARTIFACTS }}
          workflow: test.yml

# (2)
WORKDIR /tmp

# (3)
RUN pip install poetry

# (4)
COPY ./pyproject.toml ./poetry.lock* /tmp/

# (5)
RUN poetry export -f requirements.txt --output requirements.txt --without-hashes

# (6)
FROM python:3.9

# (7)
WORKDIR /code

# (8)

Stellen Sie sicher, dass Sie über die neueste Version von pip in Ihrer lokalen Umgebung verfügen, um Fehler bei den nächsten Schritten zu vermeiden:

<div class="termy">

```console
$ python -m pip install --upgrade pip

---> 100%
```

</div>

!!! tip "Tipp"
    Aktivieren Sie jedes Mal, wenn Sie ein neues Package mit `pip` in dieser Umgebung installieren, die Umgebung erneut.

## Verwendung von `TestClient`

!!! info
    Um `TestClient` zu verwenden, installieren Sie zunächst <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

    Z. B. `pip install httpx`.

Importieren Sie `TestClient`.

Erstellen Sie einen `TestClient`, indem Sie ihm Ihre **FastAPI**-Anwendung übergeben.
