Note

Tools used

Dockerfile

• The Dockerfile copies the tests/ directory from the host to image's filesystem. It also runs poetry install which will install development dependancies as well.
• You may choose not to copy the tests/ directory
• and you may install only the dependancies required by the application, by running poetry install --no-dev
• I choose to include the tests and dev dependancies as well because the size of that is relatively small.

• This also helps to test the the application in the docker environment. (that is very important) suppose your python application starts using chromedriver which is already installed in your system. So running tox in your system, passes all tests. But you forgot to include a line in the Dockerfile that will install chromedriver, but The build will still be succesful, but your application will fail to run in production.

• To run tests inside the container

shell docker run -it pyproject poetry run pytest

More details to be added soon!
