What it does

This skill gives the agent a test-driven development playbook for Java Spring Boot services. When you add a feature, fix a bug or refactor, the agent writes failing tests first, then the minimal code to pass them, then checks coverage with JaCoCo aiming for 80% or more. It supplies example patterns for unit tests, web-layer tests, integration tests, database tests with Testcontainers, and CI commands for Maven or Gradle. The file is written in Spanish and contains only guidance; it does not run anything by itself.

Great for

  • Java developers building Spring Boot REST APIs who want a consistent testing approach
  • Teams that want agents to follow a test-first workflow with coverage targets
  • Developers learning how to combine JUnit 5, Mockito, MockMvc and Testcontainers

Skip it if

  • Non-Java projects, since the patterns only apply to Spring Boot and the JVM ecosystem
  • Projects that already have a different testing standard, as the agent may push these conventions over existing ones

Try asking

  • “Add a new endpoint to my Spring Boot markets API using TDD”
  • “Write failing tests first for a bug where the market list returns the wrong page”
  • “Refactor my MarketService and keep the tests green while measuring JaCoCo coverage”
  • “Set up Testcontainers with Postgres for my repository tests”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Point the agent at your existing build file so it uses your real Maven or Gradle setup and JaCoCo version
  • Ask for tests to be written before implementation and check that they fail first, as the workflow describes
  • Review generated Testcontainers configuration, since it needs Docker running locally and may pull images
