Trying to figure out some best practice for running python tests

Dockerfile

FROM python@sha256:d7728edb9e52abc58552cec26d871f474394f3ffdefbe2929da93bfa42d92b1f

# Where the project files will be installed and tested inside the container
WORKDIR /usr/local/plowapp

# Copy the project files to the WORKDIR
COPY . .

# The python version in the container is owned by the OS of the container
# We need to isolate our project from the OS requirements by installing the virtualenv
RUN pip install virtualenv==15.1.0

# Setup the venv and install the requirements in the venv
RUN virtualenv venv && \
    . venv/bin/activate && \
    pip install -r requirements.txt
