Why does this skill prefer TestRestTemplate over MockMvc?

TestRestTemplate performs real HTTP requests against a running server on a random port, providing a true E2E test environment, whereas MockMvc simulates requests within the application context without a real network stack.

Can it be used to verify software architecture?

Yes, it integrates ArchUnit to programmatically verify that your code follows architectural rules, such as preventing the domain layer from depending on the adapter layer.

Does this skill handle database migrations?

No, it assumes tools like Flyway handle schema migrations (DDL). This skill focuses specifically on @Sql for populating and cleaning up specific test data (DML) during the test lifecycle.

How are test fixtures shared across modules?

It utilizes the Gradle testFixtures plugin, which allows for sharing of test utility classes and domain objects as a separate source set that other modules can depend on.

セキュリティとテスト

Streamlines Spring Boot integration testing by implementing E2E patterns with TestRestTemplate, reusable fixtures, and database isolation.

概要

The Testing Expert skill provides specialized guidance for building robust Spring Boot integration tests within Hexagonal Architecture. It enforces high-quality testing patterns, such as using TestRestTemplate for real HTTP calls instead of MockMvc, managing test data through @Sql and Gradle testFixtures, and verifying architectural integrity with ArchUnit. By automating the setup of Testcontainers and DML-based data population, it ensures that tests are reliable, isolated, and accurately reflect real-world production scenarios.
