Test-Driven Development (TDD) for Modern Web Apps
A hands-on, project-based course designed to introduce beginners to the Test-Driven Development (TDD) methodology in modern web applications. Students will learn to write reliable, bug-resistant code by mastering the "Red-Green-Refactor" cycle. Through practical implementation of unit, component, integration, and end-to-end tests, learners will shift their mindset from "coding then testing" to "testing to guide the coding," ultimately building a robust application from scratch.

Silabus Course
01 Introduction to TDD & The Test-First Mindset
Introduction to TDD & The Test-First Mindset
- Concept Breakdown: What is TDD and why is it crucial for modern web development?
- The Core Cycle: Mastering the "Red (Fail), Green (Pass), Refactor (Optimize)" workflow.
- Paradigm Shift: Overcoming beginner challenges when shifting from traditional coding to test-first engineering.
02 Setting Up the Modern Testing Environment
Setting Up the Modern Testing Environment
- Tool Ecosystem: Introduction to modern testing frameworks (e.g., Vitest/Jest).
- Environment Configuration: Setting up the test runner within a modern JavaScript/TypeScript project.
- The First Kata: Writing the very first test-driven code using simple mathematical functions.
03 Unit Testing Core Business Logic
Unit Testing Core Business Logic
- Test Anatomy: Understanding test suites (
describe), test cases (it/test), and assertions (expect). - Pure Functions: Writing tests for data transformation and business logic without UI dependencies.
- Edge Cases & Error Handling: Identifying unexpected inputs (null, undefined) and ensuring the system fails gracefully.
04 Component Testing for Modern UIs
Component Testing for Modern UIs
- DOM Testing Fundamentals: Introduction to component testing libraries (e.g., React Testing Library).
- Rendering & Isolation: How to mount and test individual UI components in a virtual DOM.
- Accessibility-First Querying: Finding elements on the screen from the user's perspective (by role, label, or text).
05 Handling User Interactions in Tests
Handling User Interactions in Tests
- Event Simulation: Triggering user events such as button clicks, typing in text fields, and form submissions.
- State Verification: Testing dynamic component changes (e.g., conditional rendering, opening/closing modals).
- Form TDD: Building the TaskFlow input form using the test-first approach.
06 Integration Testing & Mocking External Services
Integration Testing & Mocking External Services
- The Integration Layer: Testing how multiple units and components work together.
- Mocking Dependencies: Why and how to stub external functions or database calls.
- Network Interception: Using tools like Mock Service Worker (MSW) to fake API responses and test data fetching flows.
07 End-to-End (E2E) Testing for Critical User Journeys
End-to-End (E2E) Testing for Critical User Journeys
- E2E Concepts: Understanding browser-based testing tools (e.g., Cypress or Playwright).
- Automating Workflows: Navigating pages, interacting with the app, and asserting final outcomes just like a real user.
- The Critical Path: Writing an E2E test for the complete journey of creating a task and moving it to completion.
08 Capstone Project Execution & Advanced Refactoring
Capstone Project Execution & Advanced Refactoring
- Project Initialization: Structuring the TaskFlow application repository.
- Iterative Development: Applying modules 1-7 to build out the full application sprint by sprint, strictly using TDD.
- Safe Refactoring: Identifying code smells and confidently cleaning up the codebase, knowing the test suite will catch any regressions.
Capstone Project
TaskFlow: A Mini Kanban Board
A modern, interactive web-based task management application inspired by the Kanban methodology. Students will build this application entirely from scratch using a strict Test-Driven Development approach. Every feature—from simple logic to complex UI interactions—will be backed by automated tests written before the actual implementation code.
