Testing Toolkit

A stack-agnostic collection of Agent Skills for testing strategy, test generation, and quality assurance in web projects.

What This Solves

Developers often know how to write tests (the syntax of Jest, pytest, JUnit) but struggle with what to test, when, and with which type of test. This toolkit provides AI agents with a structured methodology for making those decisions and, when asked, generating the tests themselves.

It works with any web stack and testing framework. The strategy evaluates universal testing principles, not framework-specific syntax.

Skills

Skill	Purpose	Status
testing-strategy	Decides what to test, which test type to use, and how to prioritize coverage. Generates unit, integration, and component tests on request.	✅ Available
e2e-testing	Generates end-to-end tests for critical user flows with Page Object Model, wait patterns, flaky test diagnosis, and CI/CD integration. Stack-agnostic.	✅ Available

Quick Start

Installation

Using the Skills CLI (recommended)

# Interactive install — choose which skills and agent
npx skills add magallon/testing-toolkit

# List available skills before installing
npx skills add magallon/testing-toolkit --list

Install to a specific agent

# Install to a specific agent
npx skills add magallon/testing-toolkit --skill testing-strategy -a claude-code

Install all skills to all agents

# Install everything to every detected agent (no prompts)
npx skills add magallon/testing-toolkit --all

Manual installation

git clone https://github.com/magallon/testing-toolkit.git

cp -r testing-toolkit/testing-strategy /path/to/your/skills/

Usage

Get a testing strategy for your project:

"Analyze this project and recommend a testing strategy"

Identify what needs tests:

"What are the highest priority things to test in this codebase?"

Generate tests based on the strategy:

"Generate unit tests for the authentication module following the testing strategy"

Evaluate existing test coverage:

"Review my current tests and identify gaps in coverage"

Stack Compatibility

Works with any web project and testing framework:

• JavaScript/TypeScript: Jest, Vitest, Mocha, Testing Library, Playwright, Cypress
• Python: pytest, unittest, Robot Framework
• Java/Kotlin: JUnit 5, TestNG, AssertJ, Mockito
• Ruby: RSpec, Minitest, Capybara
• PHP: PHPUnit, Pest, Laravel Dusk
