What problem does it solve?

Best practices for testing Java applications using JUnit 5, Mockito, and Spring Boot Test, enabling reliable unit tests, meaningful integration tests, and effective test slices.

Core Features & Use Cases

• Unit testing patterns: Write focused unit tests with Mockito mocks and proper verifications.
• Integration testing strategies: Use Spring Boot Test slices, WebMvcTest, and TestContainers for realistic integration scenarios.
• Test data factories: Provide reusable test data builders and factories to maximize test consistency.
• Use Case: In a typical Spring Boot project, apply these patterns to ensure robust test suites and fast feedback loops.

Quick Start

Run a minimal JUnit 5 test with Mockito in a Spring Boot service to verify basic findById behavior.
