# Spring Boot acceptance tests from Gherkin

Implement acceptance tests from Gherkin feature files in Spring Boot projects. Given a .feature file in context, find @acceptance-tagged scenarios and implement happy-path tests with @SpringBootTest, TestRestTemplate, 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)
- @SpringBootTest(webEnvironment = RANDOM_PORT), @Autowired TestRestTemplate (auto-configured, no extra dependency)
- @ServiceConnection for Testcontainers (Spring Boot 4.0.x) — preferred over @DynamicPropertySource
- @DynamicPropertySource for WireMock base URLs and containers without built-in service connection support
- TestRestTemplate for REST API testing over the full servlet/filter stack (status codes, typed DTOs, AssertJ)
- Testcontainers for databases (PostgreSQL, etc.) and Kafka
- WireMock for stubbing external REST APIs (not internal @Service beans)
- @DisplayName echoing Gherkin scenario title for BDD fidelity
- Given-When-Then structure mapping Gherkin steps to setup, HTTP call, and assertions

**Preconditions:** (1) The Gherkin .feature file must be in context. (2) The project must use Spring Boot. For framework-agnostic Java, use @133-java-testing-acceptance-tests.

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

## Constraints

Before applying any acceptance test changes, ensure the Gherkin .feature file is in context and the project compiles. If compilation fails or the feature file is missing, stop immediately.

- **PRECONDITION**: The Gherkin .feature file MUST be in context; the project MUST use Spring Boot
- **MANDATORY**: Run `./mvnw compile` or `mvn compile` before applying any change
- **SAFETY**: If compilation fails, stop immediately and do not proceed
- **VERIFY**: Run `./mvnw clean verify` or `mvn clean verify` after applying improvements
- **BEFORE APPLYING**: Read the reference for detailed examples, good/bad patterns, and constraints

## When to use this skill

- Review Java code for Spring Boot acceptance tests
- Apply best practices for Spring Boot acceptance tests in Java code

## Workflow

1. **Read reference and assess project context**

Read `references/323-frameworks-spring-boot-testing-acceptance-tests.md` and inspect the current project setup before proposing changes.

2. **Gather scope and decide target improvements**

Identify requested outcomes, constraints, and the minimum safe set of changes to apply.

3. **Apply framework-aligned changes**

Implement or refactor configuration/code following the reference patterns and project conventions.

4. **Run verification and report results**

Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions.
