Node.js Basics and Testing

In this module you will learn:

Node.js Basics:

• Node.js vs JavaScript
• Node.js CLI (usage, options, environment variables)
• Node.js Modules (standart syntax, ES6 syntax)
• NPM (package structure, CLI commands, NPM scripts, devDeps vs deps, semantic versioning, package-lock)
• Node.js API (fs, streams, path)

Types of testing:

• Unit testing
• Integration testing
• End-to-End testing

Testing concepts

• Testing pyramid
• FIRST (fast, independent/isolated, repeatable, self-validating, timely) + maintainable, properly targeted
• TDD (test-driven development)
• Code coverage

Writing tests:

• Testing tools (jest)
• AAA pattern (arrange, act, assert)
• Mocking
