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.

Branches for the exercises follow the convention {chatper_name}_exercise, eg https://github.com/python-leap/code/tree/chapter_03_service_layer_exercise

• docker with docker-compose
• for chapters 1 and 2, and optionally for the rest: a local python3.7 virtualenv

(this is only required from chapter 3 onwards)

make build make up # or make all # builds, brings containers up, runs tests

make test# or, to run individual test types make unit make integration make e2e # or, if you have a local virtualenv make up pytest tests/unit pytest tests/integration pytest tests/e2e ## Makefile There are more useful commands in the makefile, have a look and try them out.
