Java acceptance tests from Gherkin

Implement acceptance tests from Gherkin feature files. Given a .feature file in context, find @acceptance-tagged scenarios and implement happy-path tests with RestAssured, Testcontainers, and WireMock.

What is covered in this Skill?

• Parse Gherkin .feature files to find scenarios tagged @acceptance or @acceptance-tests
• Implement happy-path acceptance tests (one test per scenario)
• RestAssured for REST API testing (given/when/then, status codes, JSON body assertions)
• Testcontainers 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, testcontainers, wiremock-standalone

Preconditions: (1) The Gherkin .feature file 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.

Scope: Implements only happy-path scenarios. Use the reference for detailed examples and constraints.
