A comprehensive multi-project workshop demonstrating JUnit 5 features, testing best practices, and modern Java development techniques.
This is a multi-project Gradle build with three main components:
- Focus: JUnit 5 features and modern testing patterns
- Testing Framework: JUnit 5.13.2 (latest)
- Key Features: Parameterized tests, dynamic tests, nested tests, conditional tests, custom extensions
- Additional Libraries: AssertJ, Mockito, jqwik (property-based testing)
- Focus: Spring Boot integration with JUnit 5
- Framework: Spring Boot 3.5.3 with Spring Test
- Database: H2 in-memory database with JPA
- Testing: Repository testing, Spring context testing, database assertions
- Focus: JUnit 4 legacy support demonstration
- Purpose: Training on migration patterns and backward compatibility
- Testing Framework: JUnit 4 via JUnit Vintage Engine
- Java: 17+ (uses Gradle toolchain)
- Gradle: 8.14.2 (wrapper included)
- IDE: Any Java IDE with Gradle support
