Java Unit Testing: Write Clean Code with JUnit and Mockito

Writing functional Java code is only half the battle; ensuring it works reliably under all conditions is what separates amateur developers from professionals. This text-based course guides you through the foundational concepts of modular testing, helping you write clean, maintainable, and self-documenting test suites. What you'll learn: 1. Understand the core principles of unit testing and test-driven development. 2. Write robust test cases using the modern JUnit framework. 3. Isolate components and mock complex dependencies using Mockito. 4. Configure and implement effective logging with the Java Logging API. 5. Apply clean-code testing practices, including assertions and parameterized tests. 6. Identify and resolve common testing anti-patterns to keep your code reliable. You will start with basic testing terminology and structural patterns, then progress to advanced mocking techniques and structured logging, practicing through comprehensive written code examples. This course is designed for beginner Java developers who want to write professional-grade code; no prior testing experience is required. Start writing cleaner, more confident Java code today.
