  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by affaan-m on GitHub. Read the source before you install it.

Installation

Install the Quarkus Tdd AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/affaan-m/ECC.git /tmp/ECC
mkdir -p .claude/skills
cp -r /tmp/ECC/docs/es/skills/quarkus-tdd .claude/skills/quarkus-tdd
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Quarkus Tdd in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Quarkus Tdd on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Quarkus Tdd is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Flujo de Trabajo TDD en Quarkus

Orientación TDD para servicios Quarkus 3.x con 80%+ de cobertura (unit + integración). Optimizado para arquitecturas orientadas a eventos con Apache Camel.

Cuándo Usar

  • Nuevas funcionalidades o endpoints REST
  • Correcciones de bugs o refactorizaciones
  • Agregar lógica de acceso a datos, reglas de seguridad o streams reactivos
  • Probar rutas Apache Camel y manejadores de eventos
  • Probar servicios orientados a eventos con RabbitMQ
  • Probar lógica de flujo condicional
  • Validar operaciones asíncronas con CompletableFuture
  • Probar propagación de LogContext

Flujo de Trabajo

  1. Escribir pruebas primero (deben fallar)
  2. Implementar el código mínimo para que pasen
  3. Refactorizar con pruebas en verde
  4. Exigir cobertura con JaCoCo (objetivo 80%+)

Buenas Prácticas

Organización de Pruebas

  • Usar clases @Nested para agrupar pruebas por método bajo prueba
  • Usar @DisplayName para descripciones legibles en reportes
  • Seguir la convención de nombres givenX_whenY_thenZ
  • Usar @BeforeEach para configuración de datos comunes

Cobertura de Pruebas

  • Probar rutas felices para todos los métodos públicos
  • Probar manejo de entradas null
  • Probar casos borde (colecciones vacías, valores de frontera)
  • Probar escenarios de excepción de forma comprensiva
  • Apuntar a 80%+ de cobertura de líneas, 70%+ de ramas

Aserciones

  • Preferir AssertJ (assertThat) sobre aserciones JUnit para verificar valores
  • Para excepciones: usar JUnit assertThrows para capturar, luego AssertJ para validar
  • Para escenarios exitosos sin excepción: usar JUnit assertDoesNotThrow

Pruebas de Integración

  • Usar @QuarkusTest para pruebas de integración
  • Usar @InjectMock para mockear dependencias en pruebas Quarkus
  • Preferir REST Assured para pruebas de API
  • Usar @TestProfile para configuración específica de prueba

Frequently asked questions

What does the Quarkus Tdd AI skill do?

Desarrollo guiado por pruebas para Quarkus 3.x LTS usando JUnit 5, Mockito, REST Assured, pruebas Camel y JaCoCo. Usar al agregar funcionalidades, corregir bugs o refactorizar servicios orientados a eventos.

Why use Quarkus Tdd on TypingMind?

Because you install it once and use it with any model. Quarkus Tdd is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Quarkus Tdd in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/affaan-m/ECC/tree/main/docs/es/skills/quarkus-tdd. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Quarkus Tdd?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Quarkus Tdd?

As many as you like. As long as a model supports skills, you can use Quarkus Tdd with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Quarkus Tdd AI skill free?

Yes. It is published on GitHub by affaan-m under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
