Spring Boot Testing with JUnit 3 Domain and Persistence Layers

Spring boot testing with JUnit, in this course teaches you how to write effective and reliable tests for Spring Boot applications using the JUnit framework. You’ll learn how to set up JUnit in a Spring Boot project, create unit and integration tests, and use annotations such as @Test, @BeforeEach, and @SpringBootTest. The course explains how to mock dependencies with Mockito, test REST APIs, and verify database operations with TestEntityManager or H2 in-memory databases. You’ll also explore how to structure test cases, apply assertions, and measure code coverage for better software quality. Through hands-on examples, you’ll practice building testable applications and applying test-driven development (TDD) principles. By the end of this course, you’ll be confident in using JUnit to ensure your Spring Boot projects are robust, maintainable, and bug-free. ProgrammingKnowledge
