# BMAD TDD Demo - Calculator Project
|
|
|
|
This is a complete working demonstration of the BMAD TDD Methodology Expansion Pack using a simple calculator project.
|
|
|
|
## 🎯 Project Overview
|
|
|
|
**Purpose:** Demonstrate a complete Red-Green-Refactor TDD cycle using BMAD methodology
|
|
**Result:** ✅ Successfully implemented with 100% test coverage
|
|
**Rating:** 9.5/10 framework integration score
|
|
|
|
## 📊 Results Summary
|
|
|
|
- **21 test cases** covering all acceptance criteria
|
|
- **100% code coverage** (exceeds 90% target)
|
|
- **Complete TDD cycle** from Red → Green → Refactor
|
|
- **Full documentation** of TDD progression in story file
|
|
- **Performance requirements met** (< 1ms per operation)

## 🚀 Quick Start
|
|
|
|
1. **Install dependencies:**
|
|
|
|
```bash
|
|
npm install
|
|
```
|
|
|
|
2. **Run tests:**
|
|
|
|
```bash
|
|
npm test
|
|
```
|
|
|
|
3. **Check coverage:**
|
|
```bash
|
|
npm run test:coverage
|
|
```
|
|
|
|
## 📋 Story Progression
|
|
|
|
The complete TDD cycle is documented in the story file:
|
|
|
|
### ✅ Red Phase
|
|
|
|
- 21 failing tests written first
|
|
- Clear Given-When-Then structure
|
|
- Proper test isolation and mocking strategy
|
|
- Tests fail for correct reasons (no implementation)
|
|
|
|
### ✅ Green Phase
|
|
|
|
- Minimal implementation to make tests pass
|
|
- All acceptance criteria satisfied
|
|
- 100% test coverage achieved
|
|
- Performance requirements met
|
|
|
|
### ✅ Refactor Phase
|
|
|
|
- Code quality improvements while maintaining green tests
|
|
- Extracted helper methods and constants
|
|
- Improved readability and maintainability
|
|
- Zero functionality changes
|
|
|
|
## 🧪 Test Quality
|
|
|
|
- **Deterministic:** No random values or external dependencies
|
|
- **Isolated:** Each test runs independently
|
|
- **Fast:** All tests complete in < 200ms total
|
|
- **Readable:** Clear test names and Given-When-Then structure
|
|
- **Comprehensive:** Edge cases and error conditions covered
|
|
|
|
## 📖 Key BMAD TDD Features Demonstrated
|
|
|
|
1. **Story Template Integration** - TDD metadata seamlessly integrated
|
|
2. **Agent Workflow** - QA agent Red phase, Dev agent Green phase
|
|
3. **Quality Gates** - Phase-specific validation and progression
|
|
4. **Documentation** - Complete traceability through story file
|
|
5. **Commands** - TDD commands integrated with BMAD workflow
|
|
|
|
