What problem does it solve?

This Skill helps you catch Spring Boot test anti-patterns that make suites slow, fragile, or misleading, especially when the wrong test slice or mock strategy hides real defects.

Core Features & Use Cases

• Slice Selection Review: Checks whether a test should use Spring Boot integration, MVC, JPA, JSON, or another narrower slice.
• Mock and Context Hygiene: Flags excessive mocking, misuse of Spring test annotations, and unnecessary full-context bootstrapping.
• Isolation and Data Strategy: Evaluates context reset behavior, transactional rollback, security context setup, and database choices such as Testcontainers versus H2.
• Use Case: A team asks why controller tests are slow and brittle; this Skill identifies overused full-context tests and recommends the most appropriate Spring test pattern.

Quick Start

Review the attached Spring Boot test files and recommend the best slice annotation, mocking approach, and isolation strategy for each test.
