Lab 1: Build CI/CD Solution

Overview

In this lab, you will learn how to implement Continuous Integration (CI) and Continuous Deployment (CD) processes using a Makefile and the Click test runner. You will perform linting, formatting, refactoring, and testing on a Python script to ensure its quality and functionality.

Goals

By the end of this lab, you will:

1. Understand the importance of CI/CD processes in MLOps.
2. Learn how to use a Makefile for automating linting, formatting, refactoring, and testing.
3. Gain experience in writing tests for command-line tools using the Click test runner.

Getting Started

Before you begin, watch the videos and read the resources in this module to familiarize yourself with CI/CD, Makefiles, and the Click test runner. These materials will help you navigate through the lab tasks and achieve the desired outcomes.

Lab Tasks

1. Source the virtual environment:
   source /home/coder/venv/bin/activate
2. Run the following steps of the Makefile:
   • make lint
   • make format
   • make refactor
   • make test

Reflection Question: Why does refactor combine lint and format?

3. Run the following command-line tool and then write a test for it using the Click test runner:
   • Write a test for the add_cli functionality of the main.py function in the test_main.py test file.
   • Use the test for ./main.py --help as a guide.

Reflection Question: How could you use this style of testing to build MLOps tools quickly?
