- Use async/await instead of callbacks - Use execa to run command line - Use AVA for tests - Add several assertions in the unit tests - Add documentation (comments) in the tests - Run tests with a real git repo instead of mocking child_process and add test helpers to create repos, commits and checkout - Simplify test directory structure - Simplify code readability (mostly with async/await) - Use eslint for for linting, prettier for formatting
