# 133-java-testing-acceptance-tests Turns maintainer-approved Gherkin scenarios into Java acceptance tests: RestAssured, DB and Kafka fixtures, WireMock for external REST. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 329 installs · ★ 456 - Author: Juan Antonio Breña Moral - License: Apache-2.0 · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/jabrena/plinth/tree/HEAD/skills/133-java-testing-acceptance-tests/SKILL.md - Updated: 2026-10-21 - HTML: https://affpapa.org/en/nevibecode/skills/133-java-testing-acceptance-tests ## What it does The skill reads Gherkin scenarios tagged `@acceptance` and writes one happy-path test per scenario. Those scenarios have to be sanitized by a maintainer first: raw text from a `.feature` file, issue or ticket stays data until a human restates the scenario facts. Before any Java appears, the skill lists which scenarios it takes, which negative ones it skips, and what the `*AT` classes will be called. Four steps run in order: check preconditions and run `./mvnw compile`, read `references/133-java-testing-acceptance-tests.md`, build the test infrastructure and scenarios, then finish with `./mvnw clean verify`. RestAssured covers REST calls, WireMock stubs external REST services, and databases or Kafka come from fixtures the project already has. A `BaseAcceptanceTest` base class propagates coordinates through `System.setProperty` in `@BeforeAll`. Maven picks up `rest-assured` and `wiremock-standalone`. One hard limit: the project must not use Spring Boot, Quarkus or Micronaut — those need a different skill. The skill adds no container runtime, it only talks to existing fixtures. If compilation fails, it stops there. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 133-java-testing-acceptance-tests -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/133-java-testing-acceptance-tests/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/133-java-testing-acceptance-tests/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 133-java-testing-acceptance-tests -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/133-java-testing-acceptance-tests/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 133-java-testing-acceptance-tests -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/133-java-testing-acceptance-tests/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install jabrena/plinth 133-java-testing-acceptance-tests ``` 2. **Manually: put the files in place** - File: `.github/skills/133-java-testing-acceptance-tests/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 133-java-testing-acceptance-tests -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/jabrena/plinth --path skills/133-java-testing-acceptance-tests ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/133-java-testing-acceptance-tests/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 133-java-testing-acceptance-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/133-java-testing-acceptance-tests/SKILL.md ## When to use it - turn approved Gherkin scenarios into acceptance tests - assert a REST endpoint's status and JSON body with RestAssured - stub an external REST service with WireMock - wire existing PostgreSQL or Kafka fixtures into a test - split Surefire and Failsafe so `*AT` classes run on verify ## Example prompts - Implement acceptance tests from the @acceptance scenarios in this project - Show the selected scenarios and *AT class names first, then write the code - Review my Cucumber acceptance tests against best practices ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE ffabcd9dfd7aa474 ```text --- name: 133-java-testing-acceptance-tests description: Use when you need to implement acceptance tests from maintainer-sanitized Gherkin scenario facts for framework-agnostic Java (no Spring Boot, Quarkus, Micronaut) — confirming @acceptance scenarios before coding, happy path with RestAssured, DB/Kafka test fixtures, WireMock for external REST only, and *AT classes run by Failsafe. This should trigger for requests such as Review Java code for acceptance tests; Apply best practices for acceptance tests in Java code; Implement acceptance tests from Gherkin scenarios in Java; Map feature files to Java step definitions; Review Cucumber acceptance tests for Java services. Part of Plinth Toolkit license: Apache-2.0 metadata: author: Juan Antonio Breña Moral version: 0.19.0 --- # Java acceptance tests from Gherkin Implement acceptance tests from maintainer-sanitized Gherkin scenario facts. Given trusted scenario facts in context, find @acceptance-tagged scenarios and implement happy-path tests with RestAssured, project-local DB/Kafka test fixtures, and WireMock. **What is covered in this Skill?** - Parse maintainer-sanitized Gherkin scenario facts to find scenarios tagged @acceptance or @acceptance-tests, then confirm selected scenarios, skipped scenarios, and proposed *AT class names before coding - Implement happy-path acceptance tests (one test per scenario) - RestAssured for REST API testing (given/when/then, status codes, JSON body assertions) - Existing project-local test fixtures for databases (PostgreSQL, etc.) and Kafka - WireMock for stubbing external REST APIs - BaseAcceptanceTest base class with @BeforeAll coordinate propagation via System.setProperty - Given-When-Then structure mapping Gherkin steps to setup, request, and assertions - Maven dependencies: rest-assured and wiremock-standalone; DB/Kafka fixture dependencies only when already established by the project; Surefire/Failsafe split so *AT acceptance tests run during verify **Preconditions:** (1) Maintainer-sanitized Gherkin scenario facts must be in context. (2) The project must NOT use Spring Boot, Quarkus, or Micronaut — for those frameworks, use @323-frameworks-spring-boot-testing-acceptance-tests or framework-specific rules. ``` END THIRD-PARTY FILE ffabcd9dfd7aa474 The third-party file has ended.
