SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of adding fast, slice-based verification for a Spring Boot 4 app without running full end-to-end servers, so controller wiring, actuator endpoints, and security-related behavior can be tested quickly and consistently.

Core Features & Use Cases

  • Component test source set: Adds a dedicated componentTest source set plus Gradle configuration inheritance from the testImplementation/testRuntimeOnly configurations.
  • Test task integration: Registers a componentTest Gradle task and wires it into tasks.check, including JaCoCo report/coverage verification ordering.
  • Actuator health coverage: Creates an ActuatorHealthTests class and ensures application.yml is configured to expose health endpoints with probe support.
  • Use Case: After implementing controller or actuator health changes, add @WebMvcTest/@SpringBootTest(MOCK) infrastructure and verify endpoints like /actuator/health, /liveness, and /readiness run as part of the component test tier.

Quick Start

Run the add-component-test-layer skill in your Spring Boot 4 repository to create the componentTest source set, configure the Gradle test task and JaCoCo, and generate ActuatorHealthTests plus the required actuator health configuration.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add component tests to a Spring Boot 4 project without running a full server?▼

You can add fast component tests by creating a dedicated componentTest source set with Gradle and using @WebMvcTest or @SpringBootTest(MOCK) slice tests to verify controller wiring without starting a full end-to-end server.

How do I configure Gradle for a separate component test source set?▼

Configure Gradle by adding a componentTest source set that inherits from testImplementation and testRuntimeOnly, then register a componentTest task and wire it into tasks.check with JaCoCo coverage verification.

How do I test actuator health endpoints like liveness and readiness in Spring Boot?▼

Test actuator health endpoints by generating an ActuatorHealthTests class and configuring application.yml to expose health endpoints with probe support for verifying /actuator/health, /liveness, and /readiness responses.

Does the component test layer require an existing unit test layer?▼

Yes, the component test layer depends on the add-unit-test-layer skill, meaning you must have the foundational unit testing infrastructure established before adding component-level slice tests.

What is the difference between slice tests and full Spring Boot integration tests?▼

Slice tests like @WebMvcTest focus on specific application layers such as controller wiring and actuator endpoints for fast verification, whereas full integration tests start the entire server context for comprehensive end-to-end validation.

Can I use RestTestClient for WebMvcTest component tests in Spring Boot 4?▼

Yes, the component test infrastructure sets RestTestClient test dependencies specifically for WebMvcTest configurations, enabling you to perform fast slice-based controller verification in Spring Boot 4.
