# 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. ## Reference For detailed guidance, examples, and constraints, see [references/323-frameworks-spring-boot-testing-acceptance-tests.md](references/323-frameworks-spring-boot-testing-acceptance-tests.md).
