## What it does

This skill guides integration testing in Quarkus codebases. It sets up in-JVM tests with real CDI wiring using `@QuarkusTest` and handles Dev Services containers. HTTP endpoints run against REST Assured, while third-party dependencies rely on WireMock stubs via `QuarkusTestResourceLifecycleManager`.

The workflow enforces strict build rules. Your project must pass `./mvnw compile` before applying edits; otherwise, execution stops immediately. Running Testcontainers and Dev Services requires an active Docker daemon. Test execution separates fast `*Test` runs in Surefire from integration `*IT` suites in Maven Failsafe.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jabrena/plinth --skill 422-frameworks-quarkus-testing-integration-tests -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/422-frameworks-quarkus-testing-integration-tests/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/422-frameworks-quarkus-testing-integration-tests/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jabrena/plinth --skill 422-frameworks-quarkus-testing-integration-tests -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/422-frameworks-quarkus-testing-integration-tests/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jabrena/plinth --skill 422-frameworks-quarkus-testing-integration-tests -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/422-frameworks-quarkus-testing-integration-tests/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jabrena/plinth 422-frameworks-quarkus-testing-integration-tests
```

2. **Manually: put the files in place**
- File: `.github/skills/422-frameworks-quarkus-testing-integration-tests/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jabrena/plinth --skill 422-frameworks-quarkus-testing-integration-tests -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jabrena/plinth --path skills/422-frameworks-quarkus-testing-integration-tests
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/422-frameworks-quarkus-testing-integration-tests/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jabrena/plinth --skill 422-frameworks-quarkus-testing-integration-tests -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jabrena/plinth/tree/HEAD/skills/422-frameworks-quarkus-testing-integration-tests/SKILL.md

## When to use it
- configure Dev Services and Testcontainers for Quarkus persistence layers
- mock external HTTP endpoints using WireMock lifecycles
- set up black-box verification with @QuarkusIntegrationTest for native images
- split unit and integration test phases across Maven Surefire and Failsafe
- isolate test data using @TestTransaction or cleanup methods in @BeforeEach

## Example prompts
- Configure Dev Services PostgreSQL for our Quarkus repository integration tests
- Set up WireMock stubs for the external billing service in our Quarkus suite
- Split integration tests into Maven Failsafe and configure @QuarkusIntegrationTest

This should trigger for requests such as Add or improve integration tests in a Quarkus project; Configure Testcontainers or Dev Services for Quarkus tests; Add WireMock stubs for external HTTP dependencies in Quarkus integration tests; Set up @QuarkusIntegrationTest for packaged artifact or native binary testing; Fix test data isolation or configure Maven Surefire/Failsafe split.

# Quarkus Integration Testing

Apply integration testing patterns for Quarkus with real wiring and reproducible infrastructure.

**What is covered in this Skill?**

- @QuarkusTest for in-JVM integration with real CDI wiring
- Dev Services for automatic container provisioning (%test.quarkus.datasource.devservices)
- Testcontainers via QuarkusTestResourceLifecycleManager (start/stop lifecycle, dynamic config injection)
- WireMock for stubbing external HTTP services via QuarkusTestResourceLifecycleManager
- @QuarkusIntegrationTest for black-box testing against the packaged JAR or native binary
- HTTP testing with REST Assured against the Quarkus test port
- Data isolation: @TestTransaction for automatic rollback; @BeforeEach cleanup for HTTP tests
- Maven three-tier split: *Test → Surefire (fast), *IT + *AT → Failsafe (verify)
- Native-image test considerations with @DisabledOnNativeImage

**Scope:** Apply recommendations based on the reference rules and good/bad code examples.

## Constraints

Compile before changes; verify after; Docker may be required for containers.

- **MANDATORY**: Run `./mvnw compile` or `mvn compile` before applying any change
- **PREREQUISITE**: Project must compile before applying integration test improvements
- **SAFETY**: If compilation fails, stop immediately
- **BLOCKING CONDITION**: Compilation errors must be resolved by the user before proceeding
```
