Development Methodology

Pragmatic TDD

Category: Testing & Quality Description: A comprehensive Test-Driven Development approach grounded in Hexagonal Architecture and Domain-Driven Design principles. This skill guides you through writing tests that verify business behavior rather than implementation details.

Key Principles:

• Test via primary ports, not internal details
• Mock only at adapter boundaries (external dependencies)
• Verify complete business flows, not isolated units
• Tests survive refactoring

Best For:

• Domain-rich business logic
• DDD/Hexagonal Architecture projects
• Teams prioritizing test maintainability
• Systems requiring high confidence in business rules

Usage:

/pragmatic-tdd

Or mention in conversation:

"Use the pragmatic TDD approach to implement user registration
with competitor domain detection. Test via the primary port
(UserRegistrationService) and mock only adapters."

---

Usage

Using Skills

Skills are activated by explicitly requesting them in your conversation with Claude:

Example 1: Starting a New Feature

You: "I need to implement a feature where users from competitor
domains are flagged for manual review. Use the pragmatic TDD
approach."

Claude: [Reads pragmatic-tdd skill documentation]
Claude: "I'll guide you through this using TDD. Let's start by
writing a test for the business requirement via the primary port..."

Example 2: Code Review with Methodology

You: "Review this UserService implementation using pragmatic
TDD principles. Are we testing at the right level?"

Claude: [Applies pragmatic-tdd principles]
Claude: "I notice these tests are mocking internal validators.
According to pragmatic TDD, we should test via the primary port
instead..."

Example 3: Refactoring Guidance

You: "I want to extract this competitor detection logic into
a separate class. Will it break tests?"

Claude: [References pragmatic-tdd principles]
Claude: "Since your tests are written via the primary port
(UserRegistrationService), this refactoring won't break them..."

Plugin Scope

Plugins can be installed at different scopes:

• User scope (default): Available across all your projects
• Project scope: Install with --scope project for project-specific configuration

Use project scope when you want to version-control plugin configuration in your repository.
