Mockito for Spring: Unit Testing Spring Framework Projects (2015)

Spring Mockito Unit Testing is an essential skill for Java developers who want to build reliable, maintainable, and high-quality Spring applications. This comprehensive course teaches you how to write effective unit tests using Mockito and the Spring Framework while following industry best practices. Whether you are a Java developer, Spring Boot engineer, software tester, or backend developer, this course provides the practical knowledge needed to create robust test suites that improve application quality and accelerate software delivery.

Why Learn Mockito with Spring?

Testing plays a vital role in modern software development. Therefore, developers must ensure that every component functions correctly before deployment. Mockito simplifies unit testing by allowing you to create mock objects that isolate business logic from external dependencies. Moreover, Spring integrates seamlessly with Mockito, making it easier to test services, repositories, controllers, and application components.

Throughout this course, you will learn how to write clean, maintainable, and reusable unit tests. Furthermore, you will explore testing strategies that reduce bugs, improve code quality, and increase development confidence. As a result, you will become more productive while building enterprise-grade Spring applications.

What You Will Learn

• Understand the fundamentals of unit testing.
• Create mock objects using Mockito.
• Write effective JUnit test cases.
• Test Spring services and business logic.
• Mock repositories and external dependencies.
• Validate controller functionality.
• Use annotations such as @Mock, @InjectMocks, and @Spy.
• Verify interactions between application components.
• Improve code coverage with practical testing strategies.
• Follow testing best practices for enterprise Spring projects.

Course Modules

Introduction to Unit Testing

First, you will understand why unit testing is critical for modern software development. Additionally, you will explore the benefits of automated testing and continuous integration.

Getting Started with Mockito
