Module 5 - Getting Familiar with DevOps Processes and Tools

This directory builds on the Module 4 code which includes several Docker-related and CRM-app related content. The additions are discussed below. Note that the setup/ directory has been removed as it is assumed that Docker and docker-compose are still installed from the previous module.

Tests

This module introduced linting, unit tests, and system tests.

• .pylintrc: The configuration file used by pylint, a Python syntax and styling checker.
• src/test_unit.py: Set of unit tests to evaluate the Database class balance() and owes_money() methods. This latter method was added using test-driven development (TDD).
• src/test_system.py: Set of system tests which uses docker-compose to set up several containers then uses Python requests to test the complete functionality of all running containers.

Test Pipeline

The course demonstrated Travis CI at a high-level to illustrate how all the pieces fit together. The .travis.yml file contains the "script" that Travis will follow upon every git push or pull request (PR) operation.
