NameError: name 'pytest' is not defined - GitHub Actions

Question

I have a simple Docker image that has some python test cases.

Here's my Dockerfile

ARG PYTHON_VERSION=3.8.3-alpine

# Use the python image as the base image
FROM python:${PYTHON_VERSION}

# upgrade pip 
RUN pip install --upgrade pip

# set CUSTOMER_NAME as environment variables
ENV CUSTOMER_NAME=${CUSTOMER_NAME:-A}

# Set the working directory 
WORKDIR /app

# Create a non-root user and add the permissions
RUN adduser -D "${USERNAME:-jananath}"

# set the username - HERE WE ARE USING A DEFAULT VALUE FOR THE USERNAME, WHICH IS "jananath"
USER "${USERNAME:-jananath}"

# copy the requirements file and install the dependencies
COPY --chown="${USERNAME:-jananath}":"${USERNAME:-jananath}" requirements.txt requirements.txt
RUN pip install --no-cache-dir --upgrade --user -r requirements.txt

ENV PATH="/home/${USERNAME:-jananath}/.local/bin:${PATH}"

# copy the app code
COPY --chown=${USERNAME:-jananath}:${USERNAME:-jananath} . .

# expose the default Flask port
EXPOSE 80 

# set the entrypoint to run the app
CMD ["uvicorn", "main:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "80"]

Then I build the image:

docker build -t hello:v1 .

Then I run the app

docker run --rm -itd -p 80:80 -e CUSTOMER_NAME=A hello:v1

Then I execute the pytest

docker exec -it 570e3153ab90 pytest

And it successfully gives the pytest output as below:

================================================= test session starts =================================================

Everything works fine, except I run the same image in the `GitHub Actions.

. . .
  container-test-job:
    runs-on: ubuntu-latest
    container:
      image: ghcr.io/<USERNAME>/<REPO>/hello:v2
      credentials:
          username: ${{ github.actor }}
          password: ${{ secrets.TOKEN_REPOSITORY }}    
      env:
        CUSTOMER_NAME: A
    steps:
      - name: Test
        shell: python
        run: |
          pytest
. . .

But I get the below error:

Traceback (most recent call last): File "/__w/_temp/598eea6e-7acf-4d7c-964f-a69440ea38c2.py", line 1, in pytest NameError: name 'pytest' is not defined Error: Process completed with exit code 1.

Can someone help me understand the issue here and how to fix it?

Thank you!

try this code and after that you can build the image and push it to your registry.

name: build and test

on:
  push:
    branches:
      - "main"

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Set up Python 3.10
      uses: actions/setup-python@v4
      with:
        python-version: 3.10.6
        architecture: "x64"

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install pytest
        if [ -f requirements.txt ]; then pip install -r requirements.txt; fi

    - name: Test with pytest
      run: |
        pytest
