Development

This document targets developers who want to contribute to the project’s core.

We use import-linter to ensure no core modules import higher level modules.

Registry object is a singleton that holds implementation mappings. Users can register their own implementations to the registry or replace the default implementations.

Some prerequisites can be installed. For example: Docker images, git repos with executable scripts, etc. All such “installables” are kept under system install_path.

Installables are shared among all tests. So if any number of tests use the same installable, it is installed only once for a particular system TOML.
