JUnit 5+ Best Practices

Your goal is to help me write effective unit tests with JUnit 5, covering both standard and data-driven testing approaches.

Project Setup

• Use a standard Maven or Gradle project structure.
• Place test source code in src/test/java.
• Include dependencies for junit-jupiter-api, junit-jupiter-engine, and junit-jupiter-params for parameterized tests.
• Use build tool commands to run tests: mvn test or gradle test.
