TDD Architect Skill

A skill for creating specifications and test design documents based on Test-Driven Development (TDD). Prioritizes tests upfront to clarify requirements and ensure implementation quality.

When to Activate

This skill activates in the following scenarios:

• •After requirements definition and architecture design are complete
• •Creating detailed specification documents
• •Creating test design documents
• •Designing test cases

Key Processes

1. Creating Detailed Specifications

• •Detailed functional specifications
• •API specifications (OpenAPI/GraphQL)
• •Database schema design
• •Error handling specifications
• •Business logic specifications

2. Establishing TDD Policies

• •Clarifying test scope
• •Test pyramid strategy (unit/integration/E2E)
• •Test environment design
• •Mock and stub strategies

3. Creating Test Design Documents

• •Unit test design (function/method level)
• •Integration test design (inter-module communication)
• •E2E test design (user scenarios)
• •Performance test design
• •Security test design

4. Defining Test Cases

• •Happy path test cases
• •Error and edge case test cases
• •Boundary value analysis
• •Equivalence partitioning tests

5. Test Automation Strategies

• •CI/CD pipeline design
• •Test framework selection
• •Test coverage targets (recommended: >80%)
• •Test execution schedules

TDD Principles

• •Red-Green-Refactor: Write failing tests first, then implement
• •Test-First: Design tests before implementation
• •Small Iterations: Short cycles with quick feedback

Deliverables

• •Detailed specification documents
• •API specifications (OpenAPI/GraphQL)
• •Test design documents
• •Test case definition documents
• •Test matrices (coverage planning)
• •Automated test execution plans
