Simple REST Server Unit test Refractor the previous code so that we could execute unit test. Define a class in a separate files that has methods for GET and POST and do unit test on them

Unit tests -

• Building blocks of codes are tested : functions, methods, classes
• Isolation for functioning, catch bugs
• Automation , fast execution , replicability
• Continuous Integration: Unit tests are often integrated into the development workflow, where they run automatically each time a code change is pushed to a version control system.

How to run a unit test -

• Write unit tests separately
• Testing framework - For JS (jest/mocha)
• Organise and Run tests
• Debug and refractor
• Continuous Integration : integrated into the development workflow using C tools. These tools automatically run unit tests whenever code changes are committed to a version control system. This helps catch regressions and ensures that new code doesn't break existing functionality.

CI tools -

• automate and streamline the process of integrating code changes from multiple developers into a shared repository, testing those changes, and providing rapid feedback to the development team
• code quality, reducing integration issues, and ensuring that software is always in a working state.
• Jenkins: Jenkins is an open-source automation server that supports building, deploying, and automating any project. It offers a vast number of plugins and integrations, making it highly customisable for various development environments.
• GitLab CI/CD: GitLab provides built-in CI/CD capabilities directly within its platform. It's tightly integrated with GitLab's version control and project management features.
• GitHub Actions: GitHub Actions is a CI/CD and automation service integrated into GitHub. It allows you to define workflows in code using YAML files and execute them based on events in your GitHub repository.
