Advanced Java: Web Application Testing with Spring

Manual testing is slow, error-prone, and impossible to scale. For Java developers building modern web applications, mastering automated testing is the key to delivering reliable, production-ready code. This course guides you from the fundamental concepts of software testing to writing robust automated test suites for Spring-based web applications. You will learn how to verify your application's behavior at every level, ensuring your code remains stable as it grows. What you'll learn: Understand core testing concepts, terminology, and the testing pyramid; Write clean unit tests using JUnit and Mockito; Test web controllers and API endpoints with MockMvc; Configure and run integrated database tests using modern testcontainers; Apply modern practices like test-driven development and continuous integration basics. Starting with foundational testing definitions, the course moves step-by-step through unit testing, mocking dependencies, and performing full integration tests on your web layer. This course is designed for Java beginners who already understand basic syntax and want to learn professional testing workflows. Start writing reliable, self-testing Java applications today.
