Testing in Java: A Comprehensive Guide

Java developers often rely on robust testing frameworks to ensure code quality. Here’s a breakdown of key concepts, tools, and practices:

1. Core Testing Frameworks

  • JUnit 5 🧪: Modern testing tool with improved annotations and parallel execution support.
  • TestNG 📊: Flexible framework for complex test scenarios and data-driven testing.
  • Mockito 🧠: Popular mocking library for unit testing dependencies.

2. Best Practices

  • Write unit tests first to isolate components.
  • Use test isolation to avoid side effects between test cases.
  • Automate test reporting with tools like JaCoCo.

3. Tools and Resources
