Example application code for the python architecture book

Chapters

Each chapter has its own branch which contains all the commits for that chapter, so it has the state that corresponds to the end of that chapter. If you want to try and code along with a chapter, you'll want to check out the branch for the previous chapter.

Exercises

Branches for the exercises follow the convention {chapter_name}_exercise, eg https://github.com/cosmicpython/code/tree/chapter_04_service_layer_exercise

Requirements

• docker with docker-compose
• for chapters 1 and 2, and optionally for the rest: a local python3.8 virtualenv

pip install pytest 

# for chapter 2
pip install pytest sqlalchemy

# for chapter 4+5
pip install -r requirements.txt

# for chapter 6+
pip install -r requirements.txt
pip install -e src/

Running the tests

make test
# or, to run individual test types
make unit-tests
make integration-tests
make e2e-tests
# or, if you have a local virtualenv
make up
pytest tests/unit
pytest tests/integration
pytest tests/e2e

There are more useful commands in the makefile, have a look and try them out.
